Abstract

The invention discloses a machining treating method for a surface of an aluminum alloy casting. The machining treating method comprises the following steps that the aluminum alloy casting is put intoan electrolytic cell, an acid solution is added into the electrolytic cell, the aluminum alloy casting is subjected to surface first electrolytic treatment under the condition of 45-70 DEG C, then thealuminum alloy casting is put into the electrolytic cell again, an alkali solution is added into the electrolytic cell, the aluminum alloy casting is subjected to surface second electrolytic treatment under the condition of 60-80 DEG C, the electrolyzed aluminum alloy casting is subjected to heat treatment for 10-20 minutes under the condition of 450-600 DEG C again, then the aluminum alloy casting is put into a treatment tank, and a surface treatment solution is added into the treatment tank to place the casting for 60-90 minutes under the condition of 60-80 DEG C. According to the machiningtreating method, the adaptability of the aluminum alloy casting to the temperature change can be enhanced, the strength of the aluminum alloy casting is improved so that the aluminum alloy casting can adapt to different using environments, and the use of the aluminum alloy casting in various industries is guaranteed.

Description

technical field [0001] The invention relates to the technical field of surface processing, in particular to a method for processing the surface of an aluminum alloy casting. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. With the application of aluminum alloys in all walks of life, the requirements for aluminum alloy castings are also constantly increasing. In the existing technology, after the castings are prepared and formed, they are all polished and polished, and there is no special treatment to improve their service life. Means, for this reason, we propose a surface processing...
