Abstract
In this paper the composition of the interface of TiN and TiCN hard co atings deposited onto high speed steel substrates obtained by the arc discharge technique is studied using Auger electron spectroscopy at tw o different substrate temperatures, 520 K and 720 K. The low temperatu re (520 K) TiN coating developed an oxygen phase at the interface, pro ducing a weak adherence of 40 N, while the high temperature coatings ( 720 K) had a less intense oxygen phase, giving a greater adherence to the substrate of 60 N. The TiCN coatings at 520 K ace characterized by a low oxygen intensity at the interface. However, their adherence of 50 N is lower than the value of 60 N for the high temperature TiN coat ings and is independent of the substrate temperature.
