Abstract

Purpose The purpose of this paper is to study the effects of voltage on microstructure and properties of micro-arc oxidation (MAO) ceramic coatings formed on AZ31B magnesium alloy under the constant current–constant voltage operation mode. Design/methodology/approach The wear and corrosion resistance of MAO coating on AZ31B magnesium alloy was studied by MAO in silicate electrolyte under constant current and constant voltage. Findings When the voltage is 360 V, the wear and corrosion resistance of AZ31B magnesium alloy is the best. Originality/value The wear and corrosion resistance of MAO coating on AZ31B magnesium alloy was studied by friction wear and electrochemical workstation.

期刊介绍： Anti-Corrosion Methods and Materials publishes a broad coverage of the materials and techniques employed in corrosion prevention. Coverage is essentially of a practical nature and designed to be of material benefit to those working in the field. Proven applications are covered together with company news and new product information. Anti-Corrosion Methods and Materials now also includes research articles that reflect the most interesting and strategically important research and development activities from around the world. Every year, industry pays a massive and rising cost for its corrosion problems. Research and development into new materials, processes and initiatives to combat this loss is increasing, and new findings are constantly coming to light which can help to beat corrosion problems throughout industry. This journal uniquely focuses on these exciting developments to make essential reading for anyone aiming to regain profits lost through corrosion difficulties. • New methods, materials and software • New developments in research and industry • Stainless steels • Protection of structural steelwork • Industry update, conference news, dates and events • Environmental issues • Health & safety, including EC regulations • Corrosion monitoring and plant health assessment • The latest equipment and processes • Corrosion cost and corrosion risk management.
