Beschreibung
Zusammenfassung:	The invention discloses a surface anti-oxidation processing method for an aircraft carbon brake disc, which comprises the following steps: firstly, coating a layer of phosphate coating solution on the surface of a material needing to be processed, and forming a bottom phosphate coating through high temperature heat treatment; secondly, coating a layer of slurry coating which uses refractory ceramic powders as the main raw material and uses the phosphate coating solution as solution on the surface of the bottom phosphate coating; and finally forming a composite coating through the high temperature heat treatment. The composite coating of the invention has anticatalytic effect, and can improve the high temperature anti-oxidation capacity of C/C composite materials, such as the aircraft carbon brake disc and the like, under the condition of sea or salt spray pollution; and the ceramic component in the composite coating is melted and flows at high temperature so as to effectively heal thecrackles in the coating,
