PVD Coating vs. CVD: Two Common Coating Application Methods

WebAmong the transition metal carbides, TiC was the CVD coating dominating the coating market in the early 1970s (Ruppi, 2001; Schintlmeister & Pacher, 1975). This interest arose due to the higher hardness of TiC compared to that of TiN, which is a consequence of its more covalent bonding characteristics (Sundgren & Hentzell, 1986). WebFigure 5C shows that a crockmeter test was performed on a metal substrate, which has pigment basecoat and polyurethane clearcoat. The top portion of the substrate was further coated with a polysilazane hard coat. The polysilazane-coated region exhibits excellent scratch resistance up to 500 crocking cycles, while the area without polysilazanes shows …
