Effect of Quench Environment on the Conversion Coatings on Magnesium Alloy AZ91
The aim of the study is to achieve fine microstructure of AZ91, due to the optimized heat treatment processes, which can be easily coated with a normal conversion process as phosphating. Determination of the influence of the AZ91 microstructure, mainly precipitates which are created using different...
