Abstract:

在322、402和462L/min3种氧气流量条件下采用超音速火焰喷涂技术制备了3种TiB2-50Co涂层,通过SEM和XRD对涂层的微观组织和物相结构进行分析,测试其硬度,采用水淬法测试涂层的抗热震性能,并研究了涂层的耐熔融铝硅(Al-12.07wt%Si)合金腐蚀和耐磨粒磨损性能.研究结果表明:3种TiB2-50Co涂层的物相均为TiB2和Co;3种涂层的组织均致密,其中以氧气流量为322L/min条件下制备的涂层试样最致密,其孔隙率最低(1.76%),涂层硬度值最高,达到(558±90)HV0.3;氧气流量为462L/min条件下制备的涂层抗热震性能最差,涂层截面出现明显裂纹;在熔融Al-12.07wt%Si合金中腐蚀60h后,3种涂层均具有良好的耐熔融Al-12.07wt%Si腐蚀性能;在载荷为6N的条件下,3种涂层均具有良好的耐磨损性能,以氧气流量为322L/min条件下制备的涂层试样最佳.
