Abstract

The invention discloses a surface treatment process for aluminum alloy components of a turning machine. The process comprises the steps of pretreatment and then anodic oxidation treatment of an aluminum alloy, preparation of a molecular sieve film synthetic solution and preparation of an aluminum alloy anodic oxidation film-molecular sieve film, wherein the molecular sieve film synthesis solutionis a mixed solution of tetrapropyl ammonium hydroxide, ethyl orthosilicate and deionized water, and the molar ratio of the tetrapropyl ammonium hydroxide to the ethyl orthosilicate to the deionized water in the mixed solution is 0.35:1:170. The surface treatment process for the aluminum alloy components of the turning machine has the advantages that the process is simple, and the combination of the anodic oxidation film and the molecular sieve film not only benefits the improvement of the bonding force with the surface of the aluminum alloy but also combines the advantages of two surface treatment processes, therefore, the process is environmentally friendly, economical and effective, the hardness and the corrosion resistance of the surfaces of the aluminum alloy components are improved, and the application prospects are wide.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy surface treatment technology, and in particular relates to a surface treatment technology for aluminum alloy parts of turning machines. Background technique [0002] Turning machine, a machine used for turning, also refers to lathe processing, which is a part of mechanical processing. Lathe processing mainly uses turning tools to turn rotating workpieces. Drills, reamers, reamers, taps, dies and knurling tools can also be used for corresponding processing on the lathe. Lathes are mainly used to process shafts, disks, sleeves and other workpieces with rotating surfaces, and are the most widely used type of machine tool processing in machinery manufacturing and repair factories. [0003] Aluminum alloy refers to adding a certain amount of other elements such as Si, Mg, Mn, Ti, Ni, etc. to pure aluminum. According to the different alloy elements added, it can be divided into super hard alum...
