Coated metal particles, a metal-base sinter and a process for producing same |
摘要 |
A process for producing a metal-base sinter, comprising sintering coated metal particles wherein the particles are prepared for sintering by the steps of: dispersing a powder of metal core particles in a gaseous atmosphere to form a mixture of a gas and particles in a powder of highly dispersed core particles; charging a precursor for the coat forming substance that has been formed via the vapor phase and/or a precursor for the coat forming substance in a vapor-phase state and the mixture of the gas and the powder of highly dispersed core particles that have a predetermined dispersity according to the average diameter of the core particles in a coating start region of a coating space; coating the surfaces of the core particles with the coat forming substance by allowing the precursor to contact and/or impinge against the core particles; shaping and sintering the thus coated metal core particles or a mixture containing them under appropriate sintering conditions. The metal-base sinter of high performance thus produced is uniform, dense, and sintered firmly to provide a fine and highly controlled microstructure.
