Steam-derived multi-functionalization of aluminum alloys

Abstract

Aluminum (Al) alloys are widely used as lightweight structural metals and are increasingly being applied to various components such as transportation equipment. This study describes a novel corrosion protection method of for Al alloys using steam, called the steam coating process. The process involves the formation of hydroxide crystals on the surface of the Al alloy, which increases its corrosion resistance by acting as an anticorrosive film. At the same time, precipitation hardening can be achieved by utilizing the steam’s thermal energy, increasing the strength of the alloy. This study will provide examples of the multi-functionalization of Al alloys through the steam coating process.
