Latest Patents
One of his latest patents is for multilayer coatings of metal-cutting tools. This multilayer coating consists of alternating layers of two components, one being a nitride or carbide of a metal from group IV, and the other a nitride, carbide, boride, or silicide of a metal from group VI. The layer thickness of the group IV metal compound ranges from 0.05 to 0.5 micrometers, while the group VI metal compound constitutes 15 to 40 percent of the layer thickness of the group IV metal compound. This multilayer coating is particularly designed for application to metal-cutting tools used in machining high-alloyed materials. Another significant patent is a cutting tool hardening method. In this method, the tool is heated in air to a temperature between 130°C and 560°C to produce an oxide film that is 200 to 10,000 angstroms thick on its surface. This film is then coated with a wear-resistant material through vacuum deposition.
