碩士 === 國立彰化師範大學 === 工業教育與技術學系 === 107 === In this study, a powder metallurgy technique was used to make copper-based brake pads. In order to protect environment and follow the related standards the mechanical properties of 35 wt.% Cu with modification components was investigated. The results showed that the specimen with 20 wt.% Ni has high solid solubility in 35 wt.% Cu. Moreover, both of V and Si improved the bonding and shear strengths of the specimens. In which the contents of Sn, Si and Ni were positive related with the tendency of shear strength, however, the high ratio of Zn has negative effect on the hardness and strength of specimens. On the other hand, the control of diffusion concentrations during sintering were determined by diffusion theory with the combination of sintering temperatures and times. The intention of which were decreasing the power consumption of sintering procedure and maintaining the strength of low-copper specimens, and it was verified by the results of final shear tests.
