Construction machinery supplies wear-resistant parts. Wear-resistant materials are a large class of new materials with special electrical, magnetic, optical, acoustic, thermal, mechanical, chemical and biological functions. They are in high-tech fields such as information technology, biotechnology, and energy technology. An important basic material for national defense construction, but also plays an important role in the transformation of certain traditional industries, such as agriculture, chemical industry, building materials, etc.. There are many types of wear-resistant materials and a wide range of uses. A large-scale high-tech industry group is forming Broad market prospects and extremely important strategic significance. According to the performance of wear-resistant materials, they can be divided into microelectronic materials, optoelectronic materials, sensor materials, information materials, biomedical materials, ecological environment materials, energy materials, and smart (smart) materials. Materials. Since we have regarded electronic information materials as a separate category of new materials, the new wear-resistant materials referred to here are the main wear-resistant materials other than electronic information materials. The supply of wear-resistant parts for construction machinery is the core of the new material field , It plays an important role in promoting and supporting the development of high-tech. In the field of global new material research, wear-resistant materials account for about 85%. With the advent of the information society, special wear-resistant materials play an important role in the development of high-tech The promotion and supporting role of the world is a key material in high-tech fields such as information, biology, energy, environmental protection, and space in the 21st century. .
