摘要: 随着对材料服役过程中吸附、粘结等表面现象的研究,表面新型复合涂层材料的研究快速发展并开始逐渐取代传统材料。利用表面工程技术制备出各种不同类型的涂层材料以满足耐蚀、耐磨、耐高温等性能要求,目前获得的涂层,仍然存在内部孔隙率高、粘结强度低、断裂韧度差等缺陷。大量研究表明稀土元素及其氧化物对于改善涂层组织及性能具有重要作用。讨论了稀土或其氧化物对涂层的影响,重点综述了稀土对涂层微观组织细化方面的作用,稀土改性涂层在耐蚀性方面的主要研究结果,并分析了稀土影响作用机制。在此基础上,还探讨了稀土改性涂层的未来研究前景。

Abstract: With the development of research about the surface phenomena such as adhesion and adsorption, the new kinds of composite coatings are developed rapidly and gradually replacing traditional materials. The aim of various surface engineering techniques is to manufacture composite coatings with excellent corrosion resistance, high wear resistance and high temperature resistance. At present, there are still defects such as high internal porosity, low bond strength and low fracture toughness for the composite coating fabricated through various surface preparation techniques. Numerous studies show that the rare earth elements and their oxides have an important effect on improving the structure and properties of coatings. The effects of rare earth or its oxide additives on coatings are discussed, and an overview of the effects on refinement of coating microstructure is focused on, as well as the improvement of corrosion properties, and the mechanism of rare earth effects are illustrated in detail. On this basis, the future research prospects of rare earth modified coatings are also discussed.

Key words: rare earth, composite coatings, microstructure, corrosion resistance
