采用热喷焊方法在中碳钢基体上制备了添加CeO 2的NiCrWRE合金涂层。通过拉伸试验测定了涂层的结合强度，达到300- 350 MPa。在干滑动磨损条件下，涂层的磨损行为进行了研究，并与没有添加CeO 2的NiCrW涂层进行了比较。结果表明，CeO 2的加入显著提高了热喷焊层的硬度和耐磨性。磨损表面的分析表明，涂层与CeO 2添加显示出改善的耐磨性比涂层没有CeO 2。
NiCrWRE alloy coatings with the addition of CeO2were produced on a medium-carbon steel substrate by thermal spray welding. The bonding strength of the coatings was measured by tensile testing and reached 300–350MPa. The wear behavior of the coatings was investigated under dry sliding wear conditions, and was compared with that of NiCrW coatings produced without the addition of CeO2. The results show that the hardness and wear resistance of the thermal spray welded coatings are significantly increased with the addition of CeO2. Analysis of the worn surfaces revealed that the coatings with CeO2addition show improved abrasive wear resistance over the coatings without CeO2.
