Beneath plasma nitriding, other thermochemical treatments in plasma also went through a major development: nitrocarburising, nitrocarbosulphuring and plasma carburising
. All these processes are based on the diffusion phenomenon of non-metals (nitrogen, carbon, sulphur) in the base material crystal lattice.
Since the company was founded in 2003, it has developed an extensive range of special process capabilities including heat treatment and vacuum brazing, vacuum carburising
, air plasma spray and high-velocity oxygen fuel protective coatings, as well as corrosion and oxidation resistant paint coatings.
The new standard covers all major aspects of heat treatment at Bury, including vacuum carburising
. "It has also led to an investment in internal organisation," added Carpenter, "to ensure that not only are our processes controlled, but also that our selected team of aerospace specialists is fully trained to administer the appropriate procedures to meet the standard of BSEN 9100."
Intended primarily to serve the fastener markets, the new furnace line will provide carburising
and carbonisation capability to meet the growing demand for these treatments.
He will be responsible for key accounts covering the full range of WHT Group services, which include diamond-like coatings (DLC), PVD hard coatings, advanced heat treatment techniques, such as plasma nitriding and vacuum carburising
, and metallurgical advisory services.
A Tubothal heating system supplied by furnace heating specialists, Kanthal, to Japanese commercial heat treatment and furnace building company, Dowa Mining Company, has increased the furnace temperature capability and added 30 per cent carburising
