Plasma spraying ceramic powder, ceramic composite coating and preparation method thereof
The invention relates to the field of thermal spraying ceramic coatings, and particularly discloses plasma spraying ceramic powder, a ceramic composite coating and a preparation method of the ceramic composite coating. The plasma spraying ceramic powder is prepared from the following raw materials in parts by weight: 100 parts of nano powder and 10 to 30 parts of silicate glass powder, the nano powder comprises nano Al2O3 powder, nano TiO2 powder, nano CeO2 powder and nano YSZ (Yttria Stabilized Zirconia) powder in a weight ratio of (80-86): 10: 2: (2-8). The plasma spraying ceramic powder has the beneficial effects of being good in fluidity, smooth in surface, high in compactness and good in sphericity degree, and the prepared ceramic composite coating has the beneficial effects of being low in porosity, high in compactness, good in corrosion resistance and long in service life.
本申请涉及热喷涂陶瓷涂层领域，具体公开了一种等离子喷涂陶瓷粉末、陶瓷复合涂层及其制备方法。所述等离子喷涂陶瓷粉末所用原料包括以下重量份的组分：纳米粉体100份和硅酸盐玻璃粉10‑30份；所述纳米粉体包括重量比为（80‑86）:10:2:（2‑8）的纳米Al2O3粉体、纳米TiO2粉体、纳米CeO2粉体和纳米YSZ粉体。本申请的等离子喷涂陶瓷粉末具有流动性好、表面光滑、致密度高、球形度好的特点，制得的陶瓷复合涂层具有孔隙率低，致密度高，耐腐蚀性能较好的特点，服役寿命较长。
