Fabrication of Ti-Nitrides by Reactive Plasma Spray

Reactive plasma spray is a processing method which combines synthesis and deposition of reaction products in situ. This paper evaluates the effects of the chamber gas pressure, the plasma gas composition and the spray distance on the production of titanium nitrides by means of reactive plasma spraying. It describes and discusses the results obtained from experimental tests for fabrication of titanium/titanium nitride coatings onto steel substrates, with particular reference to the effects of pressure inside the spraying chamber. Paper includes a German-language abstract.
