Title:
金属-セラミックス複合材料の製造方法
Document Type and Number:
Japanese Patent JP4217279
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problems, such as absence of water resistance, incapability of increase in powder filling ratio, and increase in costs, occurring at the time when an AlN powder is used for the preparation of a preform. SOLUTION: The metal-ceramics composite is produced by forming a preform by the use of ceramic fibers or grains as a reinforcement and impregnating a metal as a base material into the preform. At this time, the preform is composed of an AlN powder having 1-100μm average grain size and 30-60vol.% powder filling ratio, and this preform is obtained by filling a vessel, made of carbon, etc., with the AlN powder to form the preform or by adding a colloidal silica solution or/and a colloidal solution of alumina hydrate to the AlN powder after water-proofing treatment, molding the resultant mixture, and then burning the resultant molded body. Further, an alloy, composed essentially of aluminum, is impregnated into the resultant preform at 700-1000 deg.C.
