Abstract

The invention discloses a metal ceramic composite wear-resistant material and a preparation method thereof. The method solves the problems that in the prior metal ceramic composite wear-resistant material, the bonding strength of metal and ceramic is low, an adhesive is easy to age, and a wear-resistant ceramic is easy to fall off and is not suitable for high temperature operating conditions. Themethod has the advantages that the metal and the ceramic are welded firmly to improve the wear resistance of the composite material, reduce the use cost, meet production requirements and the like. Thestructure of the metal ceramic composite wear-resistant material comprises a substrate which is provided with a plurality of blind holes, and wear-resistant ceramic blocks matched with the blind holes are arranged in the blind holes and are connected with the blind holes by welding.

Description

technical field [0001] The invention relates to a metal-ceramic composite wear-resistant material and a preparation method thereof, in particular to a metal-ceramic composite wear-resistant material used in a material conveying system and a preparation method thereof. Background technique [0002] In the material conveying systems of metallurgy, electric power, building materials, machinery, chemical industry and other industries, high manganese steel and wear-resistant alloys are mostly used to make wear-resistant linings. Although the liners made of metal materials have good strength and toughness, such liners are heavy in weight, low in hardness, poor in wear resistance, short in life, and need to be replaced frequently, which undoubtedly increases the labor intensity of workers and increases the Cost, downtime maintenance also reduces the utilization rate of equipment. Therefore, the development of new wear-resistant materials to improve the wear resistance of material ...
