Wear resistant materials can be divided into three categories: metals and metal compounds, ceramics and their composite materials, and plastics. Among them, metal wear-resistant materials are still in place. Metal wear-resistant materials mainly include wear-resistant cast iron, wear-resistant cast steel, non-ferrous metals, cemented carbide and metal matrix composite materials. Non-ferrous metals, cemented carbide and metal matrix composite materials. In actual engineering, the most widely used and most consumed metal anti-wear materials are still wear-resistant cast iron and wear-resistant cast steel.
