AI Technical Summary
Existing copper alloy materials lack sufficient wear resistance and self-lubricating properties in high-end equipment. Traditional additives are unevenly distributed in the matrix and have low bonding strength, which makes the materials prone to failure during high-pressure forming and friction processes, and cannot meet the requirements of harsh working conditions.
A method for preparing pretreated graphite and core-shell reinforced particles was adopted. The interfacial compatibility between graphite and copper alloy matrix was improved by vacuum pressure impregnation with phenolic resin alcohol solution and treatment with aluminum dihydrogen phosphate. The WS2-Al2O3 core-shell structure was added to form a dual lubrication system in synergy with the pretreated graphite. Yttrium oxide and lanthanum oxide powder were added to refine the grains and improve the interfacial bonding force and mechanical properties.
It achieves high wear resistance and long-term self-lubricating properties in copper alloy materials, reduces the coefficient of friction, improves the load-bearing capacity and structural stability of the materials, enhances mechanical properties, and adapts to high-speed, heavy-load and extreme temperature conditions.
