DEPOSITION AND PROPERTIES OF THICK CORROSION AND WEAR-RESISTANT TI2N COATINGS

Ti2N coatings are very interesting for corrosion and wear-resistance a pplications. It seems, however, that their introduction in industry ha s failed owing to insufficient reproducibility and scale-up problems. In this paper, a number of deposition experiments are described in whi ch the evaporation ion plating technique was used to study the influen ce of the Ti evaporation rate and the deposition temperature on the pr operties of the coating. Adhesion, thickness, hardness, structure and phase composition were determined. Only in a narrow deposition region and with strictly controlled parameters could a reproducible Ti2N coat ing be deposited.
