What are the common wear-resistant materials?
1. High-NMness metal alloys: including steel alloys (such as high manganese steel, low alloy wear-resistant steel, etc.), cast iron alloys (such as cast iron chromium alloy, etc.). These materials have high NMness and wear resistance and are often used in the manufacture of ore wear parts, wear parts of crushing equipment, etc.
2. Polymer composite materials: such as carbon fiber composite materials, ceramic composite materials, etc. These materials have lower density and excellent wear resistance and are widely used in aerospace, automotive, sports equipment and other fields.
3. Ceramic materials: including alumina ceramics, silicon nitride ceramics, silicon carbide ceramics, etc. Ceramic materials have extremely high NMness, wear resistance and high temperature resistance, and are often used in the manufacture of abrasives, bearing balls and mechanical seals.
4. Polymer materials: such as polyethylene, polyurethane, polytetrafluoroethylene, etc. These materials have good wear resistance and corrosion resistance and are often used in the manufacture of conveyor belts, seals, and lubricating materials.
5. Abrasive materials: such as diamond, corundum, silicon carbide, etc. These materials themselves have high NMness and wear resistance, and are often used in the manufacture of abrasive tools, sandpaper and grinding wheels.
