报告主要内容：
Utilisation of light-weight magnesium (Mg) alloys as engineering materials is limited due to their high affinity for oxygen and water, and hence vulnerability to corrosion. Many efforts have been attempted to address the corrosion issue of Mg alloys to pave a path for wider implementation of Mg in various applications, such as automotive, airplane, electronic devices and biomaterials. One of the intensively exploited approaches of improving corrosion resistance is applying stable and inert coatings onto the surface of Mg alloys as a barrier to provide protection functionality. Herein, we introduce some advanced techniques to develop coatings onto Mg alloys to perform either as a barrier or functional coating in order to address the corrosion of Mg. The coating characteristics, formation mechanism and their specific roles in corrosion protection will be presented and discussed. In addition, a novel pretreatment method will be introduced to demonstrate its vital role in generating a homogenous surface condition that is favorable for subsequent growth of desirable coatings
