Preparation method of continuous oxide fabric surface coating
The invention belongs to the preparation technology of continuous fiber enhanced ceramic base composite materials, and relates to a preparation method of a coating interface between fiber and a base body in the continuous oxide fiber enhanced oxide ceramic base composite material. The method includes the steps of preparing a coating phase phosphate precursor solution, soaking an oxide fiber prefabricated part in the precursor solution, taking out the prefabricated part after soaking, conducting desizing on the prefabricated part at an appropriate temperature, and obtaining a phosphate coating on the fiber surface through a repeated soaking and thermal processing process. The coating can protect fiber against mechanical and heat damage in the base body densification process and provide an appropriate weak interface combination for fiber and the base body, thereby improving strength and toughness of the material. In addition, the phosphate coating has the advantage of high temperature oxidation resistance, thereby greatly prolonging the service life of the composite material and improving high temperature reliability.
