A method for applying compound coating using a sol gel/microcapsule method is described. Orhanosilicon resin having been made into microcapsule was added to zirconia sol. The microcapsulation technique was applied to the preparation of compound coatings. Through a lot of experiments and tests, a kind of sol gel/microcapsule compound coating which has good performances of high temperature oxidation resistance and corrosion resistance has been attained. The mechanism of its good performances is that some ...
