Preparing a copper brakes of the item using a powder metallurgy process (pressure sintering mixed powder - - pressing). , The friction component and lubrication of the brake component of the film, to adjust the components studied by analyzing the brakes matrix component, excellent properties prepared copper powder brakes. Friction component by surface modification, so that brake friction material matrix powder metallurgy having a high strength, a suitable coefficient of friction, good abrasion resistance, adhesion and high temperature stability, a large temperature difference, wet, dry and other harsh environmental conditions can still ensure good stability of friction coefficient and can be used in heavy machinery and the like wind turbines and high-speed train brakes.

This project uses powder metallurgy process (powder-pressing-pressurized sintering) to prepare copper-based brake pads. By analyzing the role of brake pad base components, friction components and lubrication components in brake pads, the composition was studied and adjusted, and the copper-based powder metallurgical brake pads with excellent performance were prepared. Through surface modification of friction components, the copper-based powder metallurgical brake friction material has high strength, suitable coefficient of friction, good wear resistance, anti-adhesive and high temperature stability, and can still guarantee good coefficient and stability under harsh environmental conditions such as temperature difference, humidity and dryness. Brakes can be applied to heavy machinery such as wind turbines and high-speed trains.

This project uses powder metallurgy process (powder mixing - pressing - pressure sintering) to prepare copper base brake pads. Based on the analysis of the functions of the matrix, friction and lubrication components in the brake pad, the composition of the brake pad was studied and adjusted, and the copper based P / M brake pad with excellent performance was prepared. Through the surface modification of friction components, the copper based powder metallurgy brake friction materials have high strength, suitable friction coefficient, good wear resistance, adhesion resistance and high temperature stability, which can still ensure good friction coefficient and stability under the conditions of large temperature difference, humidity, drying and other harsh environment conditions, and can be applied to the brake of heavy machinery such as wind turbine and high-speed train. 。<br>
