【摘要】 研究了用表面涂覆含钛金属涂层的碳化硼颗粒增强 Cu基复合材料 [B4Cp/(Ti B2 +Ti N) /Cu],并与未经涂覆的 B4C颗粒增强 Cu基复合材料 (B4Cp/Cu)进行了对比。实验结果表明 ,前者的致密度和电导率比后者好。磨损实验结果表明 ,使用有涂层颗粒的复合材料的耐磨性比无涂层颗粒的好。通过对复合材料界面和磨损表面的电镜观察表明 ,B4C颗粒经过涂覆处理后 ,改善了复合材料的界面粘结性能 ,颗粒与基体间有良好的浸润性更多还原

【Abstract】 The B 4C particles containing titanium metal coating reinforced copper matrix composite(B 4C p/(TiB 2+TiN)/Cu) was investigated and compared with B 4C particles reinforced copper matrix composite(B 4C p/Cu) The experimental results show that the density and conductance of the former were better than which of the later The wear experimental results show that the wear resistance of the former is better than that of the later The interface of composites and worn surface were observed and analyzed The results indicate that the coating modification of B 4C particles has improved interfacial bonding property of composite There is good wettability between the particle and matrix更多还原
