Abstract
The invention discloses a protection method for a non-cemented anodized surface of an aluminum alloy part. The protection method comprises the following steps of a, preparing two kinds of coating used for coating the non-cemented anodized surface of the aluminum alloy part for cemented anodizing protection; b, degreasing the surface of the aluminum alloy part; c, assembling and suspending the aluminum alloy part; d, coating the non-cemented anodized surface of the aluminum alloy part with double protection layers of the two kinds of coating; e, conducting cemented anodizing treatment on the aluminum alloy part; and f, cleaning the protection layers and obtaining the qualified part without film missing. According to the protection method for the non-cemented anodized surface of the aluminum alloy part, the non-cemented anodized surface is coated with one coating protection layer of one material at first, and the non-cemented anodized surface is coated with the other coating protection layer of a different material after the previous coating is solidified, so that the coating protection layers of the two materials adhere to each other. Even if the outer protection layer is partially dissolved or cracked, the inner protection layer still has a protective effect.
Description
technical field [0001] The invention relates to the technical field of partial hard anodized treatment of aluminum alloy parts, in particular to a method for protecting the non-hard anodized surface of aluminum alloy parts. Background technique [0002] In various machinery manufacturing industries, especially in the aerospace field, in order to reduce the weight of machines, aluminum and aluminum alloy materials are used more and more widely. Therefore, in order to improve the hardness and wear resistance of certain parts of aluminum and aluminum alloy parts, hard anodizing treatment is a very effective means (after hard anodizing, HV can reach 250-500); In addition, aluminum and aluminum alloy parts are out of tolerance, and most of them use hard anodizing to remedy the size. Therefore, the hard anodization of general aluminum and aluminum alloy parts is partial, and the surface that does not need hard anodization must be strictly protected. Generally, the hard anodizing...
