| 成果简介 | NOVELTY - Invention relates to production of metal-diamond composite material. It can be used for production of power semiconductor devices and electric power converters. Dispersed diamond particles are placed in a mold from a refractory non-wettable material, which forms the geometry of the article, with embedded elements from matrix material located along interface with filler, providing fixation and retention of filler particles from floating and transverse movements, and vibration compaction is performed. Mold is placed in the reaction chamber and vacuum degassing is performed. Heating is carried out to a temperature of at least 50 °C above the melting point of the matrix material and impregnation is carried out using mechanical pressure on components of composite from 0.01 to 0.1 MPa due to loading of the punch of the mold. Contact angle of matrix material wetting with respect to mold material is ≥90°. USE - Powder metallurgy. ADVANTAGE - Higher efficiency and quality of products. 6 cl, 4 dwg, 1 tbl, 8 ex |
