Abstract
Tools having a surface coating of at least one compound containing at least one element from the main group of Group VI of the periodic table and at least one element from the subgroup of Groups V and VI of the periodic table. The coating may consist of molybdenum disulfide, for example. These tools are superior to conventional hard-solid covered tools in various respects and may be milling cutters, for example, which have an excellent edge life, even more than six times as long. Moreover, the machined surfaces have substantially less surface roughness and make it possible to work with higher feeds.
Claims20
A tool having improved wear resistance for metal-cutting machining of materials, comprising:
- a surface coating on said tool comprising at least one compound containing at least one element from the main group of Group VI of the periodic table and at least one element from the subgroup of Groups V and VI of the periodic table.
A tool having improved wear resistance for metal-cutting machining of materials selected from the group consisting of aluminum alloys, titanium alloys, platinum and alloys thereof, and copper alloys, said tool having a surface coating comprising at least one compound containing at least one element from the main group of Group VI of the periodic table and at least one element from the subgroup of Groups V and VI of the periodic table, made by the method comprising:
- coating said tool by physical vapor deposition with at least one compound of said at least one element from the main group of Group VI of the periodic table and said at least one element from the subgroups of Groups V and VI of the periodic table.
