Abstract

<p>Al alloys, the most commonly used lightweight structural metals, are expected to be applied to a wider range of components such as transportation equipment. This paper describes a novel control method of corrosion protection for Al alloys using steam, i.e., the steam coating process. In this process, hydroxide crystals are densely formed on the Al alloy surface, exhibiting an increase in corrosion resistance because hydroxide crystals behave as an anticorrosive film. At the same time, precipitation hardening can be achieved by utilizing the thermal energy of the steam, resulting in increasing the strength of the alloy. Examples of the multi-functionalization of Al alloys by the steam coating process will be presented.</p>
