Pulse plasma system

Useful dimensions: Ø 800 x 1300 mm
Ø 1200 x 1900 mm
Ø 1500 x 2100 mm Procedure: Plasma nitriding DEW-Härterei Technik offers plasma nitriding. This treatment is carried out in a modern tandem pulse plasma facility. Plasma diffusion treatment is a thermochemical heat treatment process in which the chemical composition of a material is intentionally changed in the surface layer area by diffusing one or more elements (e.g. nitrogen) in or out. Pulsed plasma technology can be used in practically every branch of industry where abrasion, corrosion and wear must be counteracted by a hard surface. In addition, the service life of the workpieces is increased accordingly. The workpieces are exposed to a relatively low temperature during pulse plasma nitriding, which ensures high dimensional stability. The core hardness is not affected. Therefore a post treatment is not necessary. The structure, thickness and hardness of the nitriding layer are controllable and can be individually adapted to the application. Plasma nitriding is a modern and environmentally friendly process technology for the surface hardening of finished tools Example: Mould plate made of 1.2312 quenched and tempered, plasma nitrided Advantages
