For example, agriculture, chemicals, and building materials play an important role. There are many types of wear-resistant materials and a wide range of uses. A large-scale high-tech industry group is being formed, which has a very broad market prospect and extremely important strategic significance. Wear-resistant materials can be divided into microelectronic materials, optoelectronic materials, sensor materials, information materials, biomedical materials, ecological environment materials, energy materials and smart (smart) materials according to their performance. 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.
Wear-resistant materials are the core of the field of new materials and play an important role in promoting and supporting the development of high-tech. In the field of global new materials research, wear-resistant materials account for about 85%. With the advent of the information society, special wear-resistant materials play an important role in promoting and supporting the development of high and new technology. They are key materials in high-tech fields such as information, biology, energy, environmental protection, and space in the 21st century. They have become countries all over the world. The focus of research and development in the field of new materials is also a hotspot of strategic competition in the development of high technology in various countries around the world.
