<p>PURPOSE:To provide a sintered product, of ceramics, cermet and metal with an extremely high strength laminated structure, which is used, for example, as a material for a cutting tool. CONSTITUTION:At least, one type of metal compound powder and ferrous metal powder used for the formation of a sintered product are filled in layers, and then are charged in pressurized nitrogen. Further, these materials are sintered in one piece in a short time by reaction heat generated by a chemical chain reaction between metal silicon powder and nitrogen.</p> |
