Surface treatment method for ceramic thermal spray coating film and ceramic thermal spray coating film
The present invention provides a surface treatment method for smoothing the surface of a ceramic thermal spray coating film and a ceramic thermal spray coating film subjected to surface smoothing treatment. A surface treatment method for a ceramic thermal spray coating film, characterized in that a slurry is sprayed onto the surface of the ceramic thermal spray coating film at a pressure of 0.01-1.0 MPa using a compressed gas, and the surface of the ceramic thermal spray coating film is smoothed. The slurry contains a liquid having a viscosity of 10 mPa/s or less at a temperature of 20 DEG C and a powder medium having a polyhedral shape and a median diameter (D50) of 1-50 [mu] m, the content of the powder medium being 1-50 vol%.
本发明提供使陶瓷热喷涂覆膜的表面平滑化的表面处理方法和实施了平滑化表面处理的陶瓷热喷涂覆膜。一种陶瓷热喷涂覆膜的表面处理方法，其特征在于，使用压缩气体以0.01～1.0MPa的压力向陶瓷热喷涂覆膜的表面喷射浆料，对所述陶瓷热喷涂覆膜的表面进行平滑化，所述浆料含有温度20℃下的粘度为10mPa/s以下的液体和具有多面体的形状且中值粒径(D50)为1～50μm的粉末介质，该粉末介质的含量为1～50体积％。
