New Plasma Nitriding Capacity for Cambridge Heat Treatment Centre

As the engineering and manufacturing supply chains emerge from the pandemic, plasma nitriding is again in significant demand for the heat treatment of new and replacement components in aerospace, automotive, motorsport and more.

BURY, U.K. - July 13, 2021 - PRLog -- Responding, Wallwork Group are upping capacity with the addition this year of two further Rübig plasma nitriding furnaces, the first due for August.

Wallwork director, Simeon Collins, explained, "This is a further £650K investment by the group, this time in our Cambridge plasma nitriding centre, increasing the existing capacity to six operational plasma nitriders, providing 24/7 processing. We are also adding a new dedicated area for inspection of case depth, structure and other quality aspects of the nitriding process."

The Rübig furnace range chosen is the Micropuls Everest. This plasma nitrider offers several advantages, including three heating and cooling zones with the temperature measured directly at the component. A blast chiller shortens process times, while optimised filling and increased energy efficiency reduce running costs.

Nitriding is a metal heat treatment process that improves the endurance of wear parts such as gears, camshafts and followers, valve parts, aero-engine and airframe  components, dies, extruder screws and injectors. In the Rübig nitrider, molecular nitrogen is cracked in plasma to obtain active nitrogen which then penetrates the component's surface. The process meets differing needs because the depth and properties of the case hardened layer can be finely controlled. Wallwork also design and manufacture the physical masking needed to ensure only the specified surfaces are exposed and hardened.

"The process has the major advantage of being relatively cool compared with other heat treatment methods. Importantly, this means the dimensions and characteristics of the base metal are not compromised. Also, it is ideally suited for low temperature plasma nitriding of stainless steels as it minimises potential loss of corrosion resistance in the metal which could compromise its use in harsh environments," Simeon added.
