摘要
利用激光技术改善等离子喷涂陶瓷层性质的研究近年来在国内外得到了广泛的关注并取得了一定的进展，将有利于拓宽等离子喷涂陶瓷层在汽车发动机、化学工业等领域的应用范围。本文从采用激光技术增加等离子喷涂陶瓷层的致密度，改善组织均匀性和相结构，提高陶瓷层的硬度、耐磨、抗蚀和抗热震等性能方面，对国内外最新研究成果进行了综述，并指出了存在的问题和发展趋势。
In recent years,the modification of plasma-sprayed ceramic coatings by laser technique has been widely investigated and made a great progress at home and abroad.It will broaden the application fields of plasma-sprayed ceramic coatings such as in automobile engines and chemical industry to an extreme extent.This paper summa-rizes the latest research achievements at home and abroad from following aspects:laser treatment of plasma-sprayed cerarnic coatings to densify the ceramic coatings,to en-hance the homogeneity of microstructure and phase structures,to increase the hardness,wear/corrosion/thermal-shock resistance.Finally,the problems remained and the de-veloping trends have been pointed out in this field.
