中文摘要:
      柱塞抽油泵柱塞(45钢)长期工作在高摩擦、高腐蚀环境下,需要提高其工作表面的耐磨性及耐蚀性以提高其工作效率、延长使用寿命。采用激光熔覆技术在45钢表面熔覆Ni60-TiC混合粉末制备金属陶瓷涂层,熔覆不同TiC含量(0%、10%、20%、30%)的涂层进行硬度测试、摩擦磨损实验及耐腐蚀实验,同时对涂层微观形貌进行表征、显微硬度检测。结果表明:涂层中加入TiC能有效改善涂层的耐磨耐蚀性能,提高涂层的硬度,降低摩擦系数。综合考虑柱塞抽油泵柱塞实际工作环境,涂层中TiC含量为20%-30%时涂层的耐磨性耐腐蚀性最好。

英文摘要:
      The plunger pump plunger (45 steel) works in high friction and high corrosion environment for a long time, and needs to improve the wear resistance and corrosion resistance of its working surface to improve its working efficiency and prolong its service life. The cermet coating was prepared by cladding the Ni60-TiC mixed powder on the surface of 45 steel by laser cladding technology, and the coatings with different TiC contents (0%, 10%, 20%, 30%) were tested for hardness test and friction and wear test. Corrosion resistance test, at the same time, the surface morphology of the coating was characterized and the microhardness was tested. The results show that the addition of TiC to the coating can effectively improve the wear resistance and corrosion resistance of the coating, improve the hardness of the coating and reduce the friction coefficient. Considering the actual working environment of the plunger pump plunger, the wear resistance and corrosion resistance of the coating are best when the TiC content in the coating is 20%-30%.
