Wear-resistant means to withstand friction.

Wear-resistant means to withstand friction.

It is a new type of material with special electrical, magnetic, optical, acoustic, thermal, mechanical, chemical and biological functions
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-tech. 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.

In view of the important position of wear-resistant materials, countries all over the world attach great importance to the research of wear-resistant materials technology. In 1989, more than 200 American scientists wrote the “Material Science and Materials Engineering in the 1990s” report, suggesting that 5 of the 6 types of materials supported by the government are wear-resistant materials. Special wear-resistant materials and product technologies accounted for a large proportion of the “American National Key Technology” report, which was updated every two years from 1995 to 2001. In 2001, the Seventh Technology Forecast Research Report issued by the Ministry of Education, Culture, Sports, Science and Technology Policy Research Institute listed 100 important topics affecting the future. More than half of the topics were new materials or topics that depend on the development of new materials, and most of them Some are wear-resistant materials. The European Union’s Sixth Framework Program and South Korea’s National Program have included wear-resistant material technology as one of the key technologies in their latest technological development plans to provide key support. Countries all emphasize the outstanding role of wear-resistant materials in developing their own national economy, safeguarding national security, improving people’s health and improving people’s quality of life.

Classification of wear-resistant products
From the perspective of application range, wear-resistant products can be divided into two parts: surface wear-resistant and mechanical wear-resistant. Widely used in ball mills in metallurgical mines, cement building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemicals, coal water slurry, pellets, slag, ultra-fine powder, fly ash, calcium carbonate, quartz sand and other industries.
