2）Chemical polishing：By step 1）Al-alloy parts after processing are inserted in basic chemical polishing liquid, carry out chemical polishing 15-
20s；The formula of the basic chemical polishing liquid is：Sodium nitrate 25-30g/L, sodium metasilicate 20-24g/L, sodium hydroxide 18-22g/
L, citric acid 32-35g/L, metal ion 10-12g/L;
3）Neutralize：By step 2）Al-alloy parts after processing, which are inserted, carries out neutralization 8-10s in sulfuric acid solution, then take out and use again
Deionized water is rinsed to the surface of the Al-alloy parts, is finally dried at 80-100 DEG C.
In a preferred embodiment of the present invention, step 2）In, the temperature of the basic chemical polishing liquid is 85-95 DEG C.
In a preferred embodiment of the present invention, the metal ion is copper ion.
The beneficial effects of the invention are as follows：Present invention process is simple and easy to control, and cost is low, is thrown using the alkali electroless of reasonable mixture ratio
Light liquid is processed by shot blasting, course of reaction unharmful substance produces, safety and environmental protection, and the Al-alloy parts after polishing have compared with
Good bright in mirror surface effect, surface can form the protection film layer with the good uniformity, can effectively improve its anti-wear performance.
