Abstract

The uses of magnesium and magnesium alloys in various fields impedes earnestly due to the low corrosion resistant and poor high temperature properties. In this present investigation, the two problems has been noticed and solved; firstly immense chemical activity and secondly the Mg alloys chemical activity has been inhomogeneous on its surface. This work tries to solve those problems by superhydrophobic (SHP) layer on AZ91D Mg alloy. The SHP surface on magnesium alloy with an angle of contact for water greater than 150° and a sliding angle lesser than 10° is a excellent water-repelling ability has been obtained. The present results confirm that this form of SHP coating has definite anti-corrosion effect in typical corrosive solution. The presented method is uncomplicated, cost effective, and environmentally friendly and has enormous potential value in the production of a large-scale industry.
