Ceramic powder for plasma spraying and method for preparing ceramic coating through plasma spraying
The invention relates to the technical field of ceramic powder, in particular to ceramic powder for plasma spraying and a method for preparing a ceramic coating through plasma spraying. The ceramic powder for plasma spraying comprises A2Hf2O7 and B2 (Zr < x > Ce < 1-x >) 2O7, wherein A is selected from at least one of Y, Ga, Gd and La; b is selected from at least one of Ga, La, Pr, Nd, Sm and Yb, and x is more than or equal to 0 and less than 1. After the ceramic powder provided by the invention is subjected to plasma spraying, a compact ceramic coating can be formed on the surface of a base material, so that the wear resistance, corrosion resistance and high temperature resistance of the base material are improved; and the coating has strong binding force with the base material, and is not easy to fall off from the surface of the base material.
本发明涉及陶瓷粉体技术领域，具体涉及一种等离子喷涂用陶瓷粉末和等离子喷涂制备陶瓷涂层的方法。所述等离子喷涂用陶瓷粉末包含：A2Hf2O7和B2(ZrxCe1‑x)2O7；其中，A选自Y、Ga、Gd和La中的至少一种；B选自Ga、La、Pr、Nd、Sm和Yb中的至少一种，0≤x＜1。本发明提供的陶瓷粉末经等离子喷涂后，能够在基材表面形成致密的陶瓷涂层，提高基材的耐磨、耐腐蚀性能和耐高温性能；且该涂层与基材之间具有强的结合力，不易从基材表面脱落。
