Abstract In order to effectively improve the heat resistance of anti-frictional bushing material, the porous Tin-Bronze alloy ZCuSn6Pb6Zn3 was used in plain bearing. Microscopic tests on ZCuSn6Pb6Zn3/Steel layered bimetallic composite specimens were conducted using such methods as SEM, EDS and XRD. The results indicate that the bonding surface forms a powder metallurgy interface without transition layer under the action of mechanochemistry when ZCuSn6Pb6Zn3 was sintered with Steel, and the porosity is calculated about 15.414%. Based on the results, the molecular model was constructed using Materials Studio and optimized by Newton-Raphson method. The mathematical model of the interface bonding energy is optimized considering the effect of porosity and simulation ensemble. The calculated results proved that the optimal bonding temperature and pressure are 920°C and 3.8MPa respectively.

层状双金属ZCuSn6Pb6Zn3/钢的界面显微结构和键合能与温度和压力的耦合

摘要 为了有效提高耐磨衬套材料的耐热性，在滑动轴承中采用多孔锡青铜合金ZCuSn6Pb6Zn3。采用SEM、EDS和XRD等方法对ZCuSn6Pb6Zn3/Steel层状双金属复合材料试样进行显微测试。结果表明，ZCuSn6Pb6Zn3与钢烧结时，结合表面在机械化学作用下形成没有过渡层的粉末冶金界面，孔隙率计算约为15.414%。在此基础上，使用 Materials Studio 构建分子模型，并通过 Newton-Raphson 方法进行优化。综合考虑孔隙度和模拟集成的影响，对界面键合能的数学模型进行了优化。
