Abstract
By applying a glow discharge in a gaseous mixture composed of TiCl 4H 2N 2, it is possible to produce TiN layers or—if the process is conducted in two stages differing in the atmosphere used—composite layers, e.g. a nitrided layer covered by a TiN layer. Electrical activation of the gaseous medium and of the surface under treatment makes it possible to reduce the treatment temperature to about 550 °C. The paper compares the properties of composite (nitrided + TiN) layers produced on 1H18N9T stainless steel (18% Cr, 9% Ni, 0.5% Ti, 0.1% C) under glow discharge conditions with the properties of layers that were only nitrided. The properties examined include the results of metallographic and phase composition measurements and the values of the wear and corrosion resistance.
