| 摘 要： | 通过在Cr2 O3 材料中加入不同含量的CeO2 添加剂 ,探讨了稀土对等离子喷涂Cr2 O3 涂层组织、抗拉结合强度和滑动磨损性能的影响。研究结果表明 ,添加适量CeO2 可以提高Cr2 O3 涂层的致密性、抗拉结合强度和耐磨性。在滑动磨损条件下 ,Cr2 O3 涂层的磨损为疲劳磨损 ,CeO2 的加入不会改变涂层的磨损失效机制。涂层的耐磨性与涂层的抗拉结合强度成正比。

| Abstract: | The additive CeO 2 with different contents was added into Cr 2O 3 to investigate the effects of rare earth on the microstructure, intensive strength, adhesive and sliding wear properties of the Cr 2O 3 ceramic coating. It is found that adding a suitable amount of CeO 2 into the Cr 2O 3 powder not only can modify the microstructure but also improve the bond and wear resistance of the Cr 2O 3 coating. The failured Cr 2O 3 coating mainly suffered the fatigue under a condition of the sliding worn. Adding CeO 2 into the Cr 2O 3 layer did not change the failure mechanism. The wear resistance of coating is directly proportional to the intensive and adhesive strengths of the coating. |
