Abstract

In order to study the effect of high energy shot peening on electrochemical corrosion resistance of WE43 magnesium alloy, the electrochemical corrosion behavior in 3.5% NaCl solution of WE43 magnesium alloy with different processing duration was investigated. Its cross-sectional microstructure, surface 3D morphology and microhardness were also examined and analyzed. The experimental results showed that the electrochemical corrosion resistance of WE43 magnesium alloy was improved after high energy shot peening. A certain thickness of plastic deformation layer was produced after treated. With the increasing of treated time, the self-corrossion potential of WE43 began to move towards a positive direction, the corrosion current density decreased.
