Abstract

The invention discloses a preparation method of metal-ceramics composite material which is obtained by combining the tape casting technique and the screen painting technique. The composite material has the advantages of good staying quality, high chemical durability and high shock resistance and overcomes the defect of low combing force among the layers of the current metal-ceramics laminar composite. The method can be used for preparing metal-ceramics composite materials in shapes of tablet, curved surface, pipe, stick and other abnormal shapes and can be used in cutters, thermocouple protecting sleeve, grinding tools, magnetic materials, heater elements, antifriction bearings and anticorrosion valves. The preparation method of the metal-ceramics composite material also has the advantages of simple preparation process, easy controlling, being easy to realize industrialization and good application prospect.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and relates to a method for preparing a composite material, in particular to a method for preparing a metal-ceramic composite material. The material prepared by the method can be used for cutters, thermocouple protective sleeves, grinding tools, magnetic materials, heating elements, wear-resistant bearings, corrosion-resistant valves and the like. Background technique [0002] Ceramic materials with a wide range of sources, low prices, high strength, high hardness, low density and excellent chemical stability are favored by people, but their poor toughness seriously hinders their application in engineering. Ceramic materials are used in a wider range of fields, and the brittleness and reliability of ceramic materials must be improved. Metals and their alloys have good ductility, electrical and thermal conductivity, and also have properties such as magnetism and wave absorption, but ...
