Effects of Annealing Ambient on the Anti-Pollution and Mechanical Properties of Functional Film Coated on the Ceramic Substrate Shan, Bowen; Kang, Hyunil; Choi, Won Seok; Joung, Yeun-Ho;
For the improvement of the anti-pollution properties of porcelain electrical insulators, in this study, we have applied the functional film to the surface of insulator. The functional films were coated on the ceramic substrates which components were like the porcelain electrical insulator. The coating material was applied to ceramic substrate by spray coating method and then the film was cured at around for 10 minutes with different gas ambient, such as , , and only vacuum. We have measured the contact angle of the coated surface, and obtained the lowest angle () and a strong hydrophilic property at vacuum condition. The anti-pollution properties were measured, revealing that as the contact angle decreased, the anti-pollution properties improved. The mechanical hardness and adhesion were both excellent regardless of the annealing ambient.
