CVD is an additive process, with an average film thickness of .006 – .009 mm., or .00024 – .00035 inches. High processing temperature (~ 1925° F) CVD is better able to coat internal surfaces than a PVD process. Pre- and post-coating polishing can achieve good final finishes. Post-coating heat treating is required on steel tools.

CVD coatings are used in many manufacturing applications as a wear-resistant coating: carbide milling and turning inserts, wear components, some plastic processing tools, etc. However, the most common …

Formation of Multilayer Coatings. The process to form multilayer carbide coatings was followed by air quenching the crucible at 950 °C at various times ranging from 0 to 30 min. A piece of KCl/Ti-Cr/CFs was embedded in a polyphenolic resin, which was polished and analyzed using SEM.
