The invention relates to a method for preparing a Y2Si2O7 whisker-toughened mullite composite coating. The method comprises the following steps: preparing a SiC porous internal coating on the matrix surface of a C/C composite material through an embedding method, preparing Y2Si2O7 whiskers, and then performing surface modification to the Y2Si2O7 whiskers with a composite surface active agent to obtain a mixed liquor; and performing ultrasonic electrophoretic selective assembly deposition to the… CONTINUE READING
