【摘要】 表面改性过程中加入稀土元素对改善材料表面的摩擦学性能有显著的效果。稀土表面工程研究中可通过多种方法将稀土元素加入表面改性层中,通常采用化学热处理、热喷涂和喷焊、激光表面处理等方法。本文综述了哈尔滨工业大学材料科学系的研究者们在该领域的研究情况,包括本文作者的研究和应用成果。更多还原

【Abstract】 The effect is remarkable for improving the tribological properties of the materials’ surface to add rare earth elements in the process of surface modification. In the researches of rare earth surface engineering, the rare earth elements can be added into the coatings or layers of surface modification in many ways, including thermochemical treatment, thermal spraying and surfacing and laser surface treating etc. This paper summarize the researches about them by the researchers in the Department of Materials Science of HIT, and the researching and applying results of the authors were discussed.更多还原
