Abstract
Mg alloy has a lot of useful properties and its application has been enlarged to various industrial products. However, it has poor corrosion resistance and therefore surface treatment is necessary. In this study, zinc oxide film formation is tried on magnesium alloy surface with RF oxygen plasma in order to improve corrosion resistance preserving good electrical conductivity. Ar gas in addition to oxygen is used to assist an easy plasma production, and the influence of argon on coating film characteristic is investigated.
