摘要
在４５钢基材上用等离子喷涂方法制备了ＴｉＣ－Ｎｉ－Ｍｏ金属陶瓷涂层，对涂层进行了性能试验、ＳＥＭ分析及ＸＲＤ分析。结果表明，等离子喷涂ＴｉＣ－Ｎｉ－Ｍｏ金属陶瓷涂层组织是均匀的，涂层硬度达到９０ＨＲＡ。涂层经频率为１６次／ｍｉｎ、６０ｍｉｎ落球冲击试验后，显微镜下未见到任何剥离痕迹或裂纹。经比较试验。
The TiC Ni Mo cermets coatings on 45 steel substrate by plasma spraying were prepared and the microstructure morphology and the phase structure of the coatings by SEM and XRD were analyzed The results indicate that the microstructure of TiC Ni Mo cermets coatings is uniform The hardness of the coatings is 90 HRA After shocked by falling ball under 16 times per minute during 60 minutes,any peeling mark or crack didnt observe in the coatings by microscope Its combining strength and toughness excels that of ZrO 2 ceramics gradient coatings by plasma spraying
