Wear-Resistant Oxide Coatings on Aluminum Alloy Formed in Borate and Silicate Aqueous Electrolytes by Plasma Electrolytic Oxidation

摘要

There are several methods known of formation of wear-resistant oxide coatings on articles made of aluminum alloys by the method of plasma electrolytic oxidation (PEO), for example, in silicate and borate aqueous electrolytes. In the present work, a comparison of characteristics of PEO coatings obtained on AMg5 and D16 aluminum alloys in the bipolar mode by these two methods, as well as in mixed borate-silicate electrolytes, has been performed.
