Abstract
The purpose of the research is to analyze the scientific and technical information to determine the possibility of strengthening the parts of aluminum alloys by microarc oxidation, in particular gear pump housings.
The article presents the results of the analysis of possibility of using a new method of hardening roboczych surfaces - micro-arc oxidation to enhance the wear resistance of working surfaces of parts made of aluminum alloys, in particular housings, gear pumps NSH. The paper describes the essence of the process of hardening parts by microarc oxidation, presents the main physical and mechanical characteristics of the hardening coating. It is noted that the adhesion strength and mechanical properties of the coating largely depend on the state of the surface to be strengthened, in particular, on the method of pretreatment. At the same time, it was found that the strengthening coating of the metal after plastic deformation has a greater adhesion strength, greater thickness and hardness. The paper presents the basic information about microarc oxidation, which, according to the authors, will contribute to the development of the method in the poorly studied method of hardening in repair production.
It can be concluded that the ceramic coatings obtained by microarc oxidation can be recommended for the restoration and strengthening of aluminum parts of gear pumps, in particular the pump housing.
Keywords
