摘　　要：等离子喷涂作为一种成熟的表面处理技术,具有适用范围广、生产效率高、涂层质量好的优点,在基体材料表面增强过程中扮演了愈发重要的角色。与此同时,越来越多的实例也证明:陶瓷涂层对提高基体材料的整体性能和服役寿命起到了关键作用。本文综述了大气等离子喷涂、超音速等离子喷涂、悬浮液等离子喷涂、真空等离子喷涂、低压等离子喷涂等常规等离子喷涂技术在制备陶瓷涂层方面的研究进展,总结了各种制备方法的优势与不足,并在此基础上对该领域的后续发展提出展望。As a mature surface treatment technology, plasma spraying for substrate play an increasingly important role in surface-enhanced process due to its wide application range, high production efficiency and good quality. Meanwhile, more and more results demonstrated that ceramic coatings play a critical role in overall performance improvement and service lifetime extension of materials. This paper reviews the development of ceramic coatings prepared by conventional plasma spraying technique, including atmospheric plasma spraying, supersonic atmospheric plasma spraying, suspension plasma spraying, vacuum plasma spraying and low pressure plasma spraying. Then, the advantages and shortcomings of each preparation method have also been summarized. Finally, based on above contents, the future development of plasma sprayed ceramic coatings are prospected.
