Problems solved by technology

With the rapid development of science and technology and modern industry, the requirements for wear resistance, toughness, hardness and other properties of materials are getting higher and higher, and the service life of materials has become an important factor affecting production progress and production efficiency; ceramic materials have High melting point, high hardness, high wear resistance, oxidation resistance and other advantages, can be used as structural materials, functional materials such as heat insulation materials; but its tensile strength, plasticity and toughness are low; combining metal and ceramic materials into composite materials, Although the nature of the metal integrates its toughness, stability and strength to enhance the stiffness, strength, creep resistance, wear resistance and other properties of the composite material, this type of composite material still cannot meet people's needs. Therefore, for metal alloys Research on composite ceramics is necessary
