CERAMIC PIECES CONNECTING METHOD Russian patent published in 1994 - IPC

FIELD: production of composite metal ceramic pieces. SUBSTANCE: method provides for production of first piece by placing mass of main metal (or mass of main metal, contacting brick of inert refractory filler), in oxidizing medium with following heating up to metal melting temperature T_m and keeping it until migration of product of oxidation in direction of oxidizer and formation of piece, that has phase of unoxidized metal. Then produced piece is placed in contact with second piece, made of uniform material or of porous oxide material, produced by other way, and repeat heating in previous terms until pieces are connected. As main metal they use titanium, zirconium, hafnium, silicon, tin, alloyed aluminum. All surfaces of first piece, that are not in contact with second piece, may be applied with barrier material. CaSO₄, CaCO₃, Ca₃(PO₄)₂ or portland cement are used as barrier materials. Additional location of main metal source beside surface of first piece, opposite to its connecting surface, is provided for. EFFECT: method is used to produce composite pieces. 4 cl, 2 dwg
