Anodic oxidation process method for carrier rocket aluminum-based composite material

The invention provides a carrier rocket aluminum-based composite material anodic oxidation process method. The carrier rocket aluminum-based composite material anodic oxidation process method comprises the following steps that S1, a product is pretreated; s2, the product treated in the step S1 is subjected to an anodic oxidation procedure; and S3, performing first-layer sealing on the product obtained in the step S2 in a K2Cr2O7 solution, and performing second-layer sealing on the product in a mixed solution containing sodium stearate. According to the anodic oxidation process method for the carrier rocket aluminum-based composite material, the corrosion prevention problem of the aluminum-based composite material in a new-generation carrier rocket is solved. Performance detection is carried out on a product produced according to an aluminum-based composite material anodic oxidation process method according to QJ469'aluminum and aluminum alloy sulfuric acid anodizing film layer technical conditions', it is fou
