Increase Metal Hardness with Heat Treatment Solutions

Here at NiTEC, our heat treatments services can be used for stress relieving and de-embrittlement as both pre-plate and post-plate treatments.  We often heat treat metals in order to increase their strength and wear resistance.

We also offer high temperature heat treatment solutions for sustained periods, which are used to diffuse the electroless nickel layer into the steel, which gives flexibility to the coating. This process does not affect the increased corrosion protection offered by this type of deposit.

Heat treatment refers to the controlled heating of metals in order to alter their properties without changing their shape.

 

From the heat treatment of specialist nickel alloy grades, to stress relieving of mild steel fabrications, the heat treatment services at NiTEC are monitored to ensure the highest quality.

Our heat treatment furnaces

The heat treatment facility at NiTEC has furnaces with ranges of 0 – 700°C.  Furnace 1 has dimensions of 1.5m x 1.5m x 2m high, and furnace 2 has dimensions of 1.7m x 1.7m x 2.2m high.

The staff at NiTEC use chart recording equipment to monitor the temperature changes of both the furnace and the work. This enables us to create heat treatment profiles which determine shotblasting solutions for many different requirements.

Our monitoring also ensures the material achieves the required temperature for the required time, in turn eliminating heat sinks on larger components or mixed loads. Small components can be loaded onto shelves to maximise the heat treatment capacity and minimise the cost of the treatment for our customers.

Nickel Plated Benches for Thomas Heatherwick

NiTEC have recently had the pleasure of nickel plating a number of benches for the English designer Thomas Heatherwick.

Known for his innovative designs and creative use of engineering and materials to produce public monuments and sculptures, Heatherwick was asked to design the Olympic Cauldron used at the London 2012 opening and closing ceremonies.

Famed for his adventurous and original use of manufacturing processes and materials across the disciplines of architecture, art and design, Thomas Heatherwick is also renowned for his innovative ideas at the forefront of manufacturing and design practice.

Thomas Heatherwick’s extruded benches began life in Heatherwick’s design and architecture studio when working on a project that involved manufacturing aluminium components through an industrial process called extrusion.

What is extrusion?

The process of extrusion involves squeezing heated metal through a shaped hole which is known as die. The heated metal produces straight aluminium lengths in this way, with a precisely shaped cross section.

However, extrusion is liable to produce very contorted shapes when the metal initially squeezes through the die. This is because the metal becomes snagged and warped as it struggles to fit. The form eventually straightens out and usually during this process; the contorted end is chopped off and melted back down.

However, Thomas Heatherwick considered the mutated sections to be more interesting by far than the straight parts, and set out to produce more warped lengths of extruded aluminium on a much larger scale.

The designer then wondered if it would be possible to use the extrusion process to create seating, much of which was needed at the time to furnish new airports and stations being built around the world. Heatherwick saw it as a simple but effective alternative to ordinary furniture that had to made up of several components and materials. These extruded seats could be made all in one go, with the legs and back of the seat formed all at once.

The Heatherwick studio hunted for a machine capable of making this dream a reality for more than 16 years, until they finally came across a new extrusion machine that had been built in the Far East. The machine was designed for use in the aerospace industry and had the capability of exerting ten thousand tonnes of pressure. The factory it came from could not actually guarantee the outcome of the experiment because the machine had never been used to its full capacity.

Nickel plating aluminium benches

Using this specialised die, Heatherwick and his studio staff made a series of aluminium benches with straight, extruded lengths, and contrasting raw, contorted ends. The sweeping parallel lines created through the extrusion process are contorted into random, gnarled endings and the arbitrary swirling forms of the bench are created through the initiation and termination of the extrusion process. NiTEC were asked to nickel plate the benches to provide a high quality surface that would be very resistant to wear. To view these benches, please click here to visit the Heatherwick studio website.

Heatherwick’s projects take the design process to its broadest reaches, from entire buildings to handbags, bridges to furniture, and always involve a radical approach to manufacturing processes and use of materials. Heatherwick is now working on more commercial products using this process to create components for architectural construction, facade design and mass produced seating ranges.

Choosing Between Electroplating and Electroless Nickel Plating

What is electroplating?

Electroplating is a process that uses an electrical current to dissolve metal so that a metal coating is deposited on an electrode. This process is called electrodeposition. The part that is to be plated is called the cathode and the anode is made of the metal which is to be plated onto the component.

The parts to be plated are then placed in a solution called an electrolyte, which contains metal salts and ions which allow the electricity to flow through it. The power supply then directs the current to the anode, which oxidises the metal atoms that comprise it and allows them to dissolve in the solution.

 

Then, the dissolved metal ions plate onto the cathode from the electrolyte solution. The rate at which the cathode is plated is always equal to the rate that the anode is dissolved.

What is electroplating used for?

Electroplating is used to change the surface properties of an object. For example, electroplating may be used to build up the thickness on a part that is slightly undersized, or to form objects by electroforming.

Electroplating may also be used where abrasion, wear resistance, and corrosion protection are an issue, to increase lubricity and for aesthetic purposes. Unlike electroless nickel plating however, the process of electroplating makes the component subject to changes in the density of the current. This results in variations in the thickness of the electroplated deposit.

What is electroless nickel plating?

Electroless nickel plating is an auto-catalytic reaction which is used to deposit a coating of nickel on a substrate. The metal is deposited when a reducing agent reacts with metal ions. Unlike electroplating, it is not necessary to pass an electric current through the solution to form a deposit.

What are the advantages of electroless nickel plating over electroplating?

Electroless nickel plating has a completely uniform coating. This means that it is a perfect solution for critical high-end engineering items including defense, healthcare, automotive and aerospace.

Electroless nickel can be deposited to produce a wide range of coating thicknesses, with uniformity and minimum variation from point to point. This uniformity can be maintained in plating both large and small parts and on components that are fairly complex, with recessed areas.

Electroplating of such parts, on the other hand, would produce thickness variation and possible voids in the plating when coating holes and inside diameters. Also, with the proper pre-plate catalyst, electroless nickel plating can deposit on non-conductive surfaces.

What is electroless nickel plating used for?

Electroless nickel plating is a plating technique commonly used to prevent corrosion and wear. The electroless nickel plating process is a high quality, cost effective solution to coating metals such as mild steel or stainless steel and can substantially extend the life of a component.

Electroless nickel plating is extremely resistant to corrosion and will therefore extend the life of everything it coats.  This makes it ideal for coating parts exposed to harsh environments such as those operating in the marine, oil and gas and defense industries. Therefore, it can also reduce the cost of repair and replacement parts.

7 Great Reasons to Choose Electroless Nickel Plating

Here at NiTEC, we know that no other metal coating has the fantastic combination of properties offered by electroless nickel. Here are 7 great reasons to choose electroless nickel plating!


1. Corrosion resistance and corrosion protection

One of the most common reasons for the use of electroless nickel coatings in functional applications is its excellent corrosion resistance. In the very corrosive conditions encountered in drilling and producing oil wells, for example, electroless nickel has the ability to withstand the combination of corrosive chemicals and abrasion.

2. Wear resistance

With the appropriate heat treatment, electroless nickel plating can be hardened up to 950vhn. This makes it ideal for areas exposed to friction and wear.

3. Hardness

A great feature of electroless nickel plating is its hardness. Hardness values for electroless nickel deposits are in the range of 450-750 VHN, depending on the phosphorous content of the deposit.

4. Lubricity

Electroless nickel plating has natural self lubricating properties, which eliminates the need for liquid lubricants on components.

5. Solderability and bondability

Electroless nickel-phosphorus alloys are easily soldered with a highly active acid flux.

6. Uniformity of deposit regardless of geometries

Electroless nickel plating has a completely uniform coating. It’s a perfect solution for critical high-end engineering items including defence, healthcare, automotive and aerospace. Electroless nickel can be deposited to produce a wide range of coating thicknesses, with uniformity and minimum variation from point to point.

This uniformity can be maintained in plating both large and small parts and on components that are fairly complex, with recessed areas. Electroplating of such parts, on the other hand, would produce thickness variation and possible voids in the plating when coating holes and inside diameters.

7. Nonmagnetic properties of high-phosphorus nickel alloy

Electroless nickel deposits containing greater than 8 percent phosphorus are considered to be essentially nonmagnetic as plated.

Advantages of a High Phosphorous Electroless Nickel Alloy

An electroless nickel coating is a dense alloy of nickel and phosphorus. The amount of phosphorus co-deposited can range from less than 2% to more than 12%, depending upon bath formulation, operating pH and bath age.

High phosphorous electroless nickel plating tanksAn electroless nickel coating with a high phosphorous content is extremely effective in the oil, gas and coal industry. These environments are highly corrosive and therefore require a phosphorous content of more than 10%.

Phosphorous content in electroless nickel deposits can vary from 1 – >12% by weight and the variation can be controlled to result in a number of deposit types.

High Phosphorus Deposits

  • Typically contain 10-12% phosphorus
  • Very high corrosion resistance
  • Complete lack of magnetic response.
  • Most conditions in the highly corrosive oil, gas and coal industry require deposits with a high phosphorus content (>10%).

Low Phosphorus Deposits

  • Typically contain 2-5% phosphorus.
  • Improved hardness and wear characteristics
  •  Higher temperature resistance
  •  Increased corrosion resistance in alkaline environments.
  • Best suited to the chloro-alkali industry, such as the transportation of liquid soda.
  • Enhanced solderability and bondability, especially in electronic applications.

Mid Phosphorus Deposits

  • Typically contain 6-9% phosphorus
  • Bright and aesthetically pleasing
  • Good hardness and wear resistance
  • Moderate corrosion resistance

Alkaline nickel-phosphorus

  • Plate at a relatively low temperatures (75-140°F, 24-60°C)
  • Suitable for plating on plastics and other nonconductive materials
  • Suitable for use on zincated aluminum.
