Abstract

Magnesium alloys (AZ91D) have excellent physical and mechanical properties. Unfortunately, MgAZ91D has a number of undesirable properties including poor wear and corrosion resistance that has obstructed its use in many applications. Therefore, it is necessary to improve the wear and corrosion performance of MgAZ91D for their future applications. Over the years, various methods of surface treatments for MgAZ91D have been studied and most frequently used are electrochemical plating technique, conversion coating, ion beam and etc. For each of the surface treatments discussed, several types of corrosion behavior and wear property have been studied with the conclusion is compared to each other.
