TiN and TiC coating on cemented carbides by ion plating

Mitsunori Kobayashi; Yoshihiko Doi

Abstract The ion plating process was employed in this study for the coating of cemented carbide inserts with a layer of TiN or TiC about 5 μm thick in order to make a comparison with the chemical vapor deposition process employed at Sumitomo Electric Industries. The study demonstrates that the wear resistance of carbides coated by ion plating is similar to that of carbides coated by chemical vapor deposition. However, the toughness obtained by ion plating is superior to that of chemically vapor-deposited coatings.
