【摘要】 为了提高工程机械金属构件表面的耐磨性,采用熔渗法制备了WC陶瓷颗粒增强BNi82CrSiB钎涂复合材料,并研究了材料的显微组织及抗磨损性能。研究结果表明,WC陶瓷颗粒相对均匀分布于基体BNi82CrSiB钎料,与Cr28合金相比,在不同外加载荷及配副颗粒尺寸条件下,钎涂复合材料具有优良的抗磨损性能,这归因于WC陶瓷颗粒优良的抗磨损性能。更多还原

【Abstract】 In order to improve the wear resistance of the metal parts of construction machinery, WC ceramic particles reinforced BNi82 CrSiB solder were prepared by infiltration, and the microstructure and wear resistance of the material were studied. The results show that the WC ceramic particles are relatively evenly distributed in the matrix of BNi82 CrSiB solder; compared with the Cr28 alloy, the solder has excellent wear resistance under different applied loads, which is attributed to the excellent wear resistance of WC ceramic particles.更多还原
