In marine atmospheric conditions, the morphologies and potential distributions of magnesium alloy were investigated underneath a droplet of 3% NaCl with microscopy and scanning Kelvin probe technique. Results showed that the deterioration process of Mg alloy could be divided into two stages unde a NaCl droplet. During the initial period, the cathodic reaction was mainly the reduction of H+. Subsequently, with the assumption of H2O and the change of the surface condition, the reduction of O2 played a vital role in the cathodic reaction. During the entire exposure process, the potential distribution images presented “valley” type potential distributions, negative at central area and positive at peripheral area. These non-uniform potential distributions could be attributed to the differential oxygen aeration under droplet. Based on above observations, a model was proposed for describing the contamination mechanism of magnesium alloy induced by NaCl droplet.
