Method for preparing C/C composite material beta-Y2Si2O7 nano-wire toughened mullite/silicate glass coating

The invention discloses a method for preparing a C/C composite material beta-Y2Si2O7 nano-wire toughened mullite/silicate glass coating. The method comprises the steps of firstly, preparing a beta-Y2Si2O7 nano-wire toughened mullite porous coating on the surface of C/C-SiC by a simple pulsed arc discharging deposition method, and then, preparing the silicate glass outer coating by adopting an electromagnetic induction heating method. The beta-Y2Si2O7 nano-wire toughened mullite/silicate glass composite oxidation-resisting coating prepared by the method disclosed by the invention is good in bonding with a base body, and the control on a composite coating structure can be achieved; the preparation cycle is short, and the process flow is simple; the preparation of the coating is completed under low-temperature conditions, so that the cost is low.
