Active Screen Plasma Nitriding
2016Conventional plasma nitriding has some limitations and disadvantages such as edge effect, hollow-cathode effect (The hollow-cathode effect usually seen in industry resulted by incorrect fixturing. This problem arises from insufficient distance between the parts to be nitrided.

Conventional DC Plasma Nitriding
2016As known before, the usual source for generating the plasma in plasma nitriding system is DC current (conventional or pulsed). This chapter just includes the results obtained by conventional DC plasma nitriding system on different grades of steels including stainless steels (austenitic, martensitic or precipitation hardening types), tool steels, and ...

Influence of oxygen in plasma nitriding
International Heat Treatment and Surface Engineering, 2009AbstractThe development of low temperature nitriding treatments to enhance wear resistance over the past 40 years is reviewed. The progress achieved is illustrated with evidence from extensive laboratory investigations and industrial trials on textile machine components and other parts.

The Plasma Spraying of Nitride Coatings
Engineering Technology Conference on Energy, Parts A and B, 2002Ceramics without oxides (i.e. nitrides) are vulnerable to oxidation in the presence of plasmagenic gases or oxygen from atmosphere during plasma spraying. Initially there were two ways of oxidation’s avoidance: first, modification of powder material and second, limitation of an oxygen’s stream flowing into plasma.
