Method for manufacturing a reaction-sintered metal/ceramic composite body and metal/ceramic composite body

摘要: A method is disclosed for manufacturing a reaction sintered composite article which comprises at least one ceramic component. The preparing particulate mixture of precursor powders leading to the formation said material upon sintering, pressing self-sustaining body, heating body up temperature below sintering initiated, comminuting heat treating selecting particles suitable grain size distribution, into shapes desired and configuration, initiated. borides, carbides, nitrides or silicides transition metal groups IVb, Vb VIb periodic table (comprising titanium, hafnium, zirconium, vanadium, niobium, tantalum, chromium, molybdenum tungsten), oxide. In case that Al2 O3, TiB2 facultatively Al, powder may comprise TiO2, B2 O3 Al. Composite bodies sizes, shapes, varying compositions other particular configurations do not allow preparation final in operation are produced by sub-sections pressed first operation, assembled shape essentially again sintered.
