Description

technical field [0001] The invention belongs to the technical field of material processing, in particular to an automatic processing device and processing method for an aluminum alloy self-lubricating surface. Background technique [0002] In order to solve the weaknesses of aluminum alloy materials such as soft surface, poor wear resistance, and high friction coefficient, it is necessary to carry out tribological surface modification treatment of aluminum and aluminum alloys. First, perform hard anodic oxidation on the surface of the aluminum alloy, and then deposit various lubricating substances on the surface of the aluminum oxide film and in the micropores. The hard oxide film makes the surface of the aluminum material have good wear resistance, and the deposited lubricating substances make it Aluminum surface has good self-lubrication. [0003] The surface of the aluminum oxide film has a nanoporous structure, which has adsorption properties for solid lubricating parti...

Problems solved by technology

However, at high temperature, nanoparticles are prone to agglomeration and growth. When the particle size is larger than the pore size of the alumina porous membrane, they cannot enter the pores. If they continue to grow, they will even form precipitates and adhere to the surface of the aluminum alloy, resulting in poor lubrication coating. uniform

[0004] The existing process equipment is controlled by manual operation, which is easy to cause manual errors and takes up human labor.

In addition, the existing process equipment uses a funnel to add the solution, which is easy to bring in air during the adding process, resulting in the failure of the vacuum state in the sealed cavity, resulting in failure of immersion or uneven film thickness.

Furthermore, existing equipment has the problem of excessive waste of solution
