英文摘要：

Diamond-like carbon（DLC） films exhibit excellent characters, such as high hardness, low friction, chemical inertness and biocompartibility. The performance of magnesium alloy can be improved by DLC film on the Mg substrate. The wear and corrosion resistance of DLC coatings on the Mg substrate using different techniques are reviewed, and also the medical foreground of DLC films on magnesium alloy is prospected. Moreover, it is predicted that DLC film on the Mg substrate will be a prospective direction for the surface treatments.
