Preparation method of SiC whisker reinforced mullite anti-oxidation coating
The invention relates to a preparation method of a SiC whisker reinforced mullite anti-oxidation coating and belongs to the technical field of preparation of high-temperature anti-oxidation/anti-corrosion coatings. A preparation route comprises steps as follows: firstly, high-performance mullite precursor sol is synthesized with a sol-gel method, then SiC whiskers are dispersed uniformly into the mullite precursor sol in a manner of ultrasound and later ball-milling, a SiC whisker reinforced mullite coating precursor suspension is obtained, then the coating precursor suspension is applied to the surface of a substrate with a high-precision dip-coating process, and finally, the SiC whisker reinforced mullite coating can be obtained after coating sintering. The preparation method breaks through a preparation technology of a whisker reinforced high-temperature anti-oxidation composite coating on the basis of the sol-gel process, has the advantages of simple process, low cost, high efficiency, high substrate shape adaptability and the like and has broad development prospect.
