Method for manufacturing metal matrix ceramic composite part

Abstract

The invention discloses a method for manufacturing a metal matrix ceramic composite part. The method includes the steps: 1) preparing a material sample; 2) detecting the performance of the material sample; 3) designing and manufacturing a casting mould; 4) placing fillers in the casting mould and performing presetting, inlaying and casting to manufacture a ceramic part wax blank; 5) embedding auxiliary materials into the ceramic part wax blank, de-waxing the ceramic part wax blank and sintering the ceramic part wax blank at a high temperature to obtain a ceramic part preform; 6) detecting the size of the ceramic part preform; 7) designing and manufacturing an infiltration mould; 8) assembling the ceramic part preform and the infiltration mould to obtain an assembly; 9) infiltrating metal into the assembly to obtain a metal matrix ceramic part precision casting blank; and 10) performing rough machining, heat treatment, semi-finishing, surface treatment, finishing and super-finishing for the precision casting blank to obtain the finished metal matrix ceramic composite part. By the method, post machining difficulty and machining amount of the part are decreased, high-precision and ultrahigh-precision machining of complicated parts are realized, the cost is low, and mass production is easily realized.

Description

Technical field [0001] The invention relates to the field of material manufacturing and machining, and in particular to a method for manufacturing metal-based ceramic material parts. Background technique [0002] Metal-based ceramics (or ceramic-based metal) composite materials have the advantages of high specific strength and specific rigidity, small linear expansion coefficient, good dimensional stability, high wear resistance, heat resistance and corrosion resistance. They are used in instruments, weapons, aviation, aerospace, etc. , Automobiles, motorcycles and other industrial fields have great application potential. [0003] Research on this material began in foreign countries in the 1960s. At present, especially the United States and Russia, the aluminum-based silicon carbide composite material in the metal-based ceramic composite material is widely used in the defense and military field, and significant results have been achieved. In China, Harbin Institute of Technology t...
