Abstract

The technology of microarc oxidation of aluminum and its alloys is one of the most promising andpopular technologies in mechanical engineering, instrumentation, aviation and space industries.Obtaining coatings with desired properties and predicting the result are among the main problemsof this technology. These problems are caused by the lack of information about coatings formedunder different electrical conditions and on different alloys. In this work, we compare the propertiesof MAO coatings obtained on different aluminum alloys at different electrical parameters. Thestructure of the obtained coatings is described, the results of measuring the microhardness along thethickness of the coatings are presented, and the assessment of abrasion resistance and adhesive abilityis carried out.
