| Abstract: | Taking HCl as catalyzer,silica sol were prepared with the tetraethyl orthosilicate sol-gel (TEOS).The sol was used for sealing treatment spraying coating at high temperature,the density and surface finish quality of coating was improved.The test result of the performance before and after coating sealing treatment shows that the resistance to acid and the resistance to corrosion at high temperature are improved greatly after sealing;meanwhile,the protection of coating on matrix is intensified by coating seal... |
