ResumoIon plating and plasma nitriding at low pressures with a glow discharge supported by a hot electron-emitting filament are studied. The properties and applications of titanium nitride coatings are discussed. Examples of their use for wear reduction in cutting are presented and their frictional properties are investigated. The triode technique is also applied in plasma nitriding and the effects on nitrogen penetration are discussed. In a steel with low contents of carbon and chromium considerable increase in the thickness of the diffusion zone is obtained by using the triode system. Further, it is shown that plasma nitriding can be combined with subsequent ion plating in order to prevent abrasive wear.
