The Influence of Polarization Tension of the Grading Over thin Layer Properties of TiN Deposed Through PDV Method

Abstract

The deposits of tough thin layers on pieces and tools through PDV method knew a permanent and constant spreading owing to the great applicability of the resulting coatings which make that the thin layer deposit from the vapour stage to become a strategically industrial technology with great development possibilities, regarding both the materials and the optimization applications of the deposits processes. In the present paper the PDV coatings studied (TiN obtained through the technology with cathodic arc) has a high hardness, a low friction coefficient and a good corrosion resistance, these properties making them excellent anti wear coatings, they are already used on a large scale in the mechanical industries, aero spatial, optics and biomedicine.
