Influence of Chloride Ion Concentration on Corrosion Behavior of WC–MgO Composite

Crystals
The influence of chloride ion (Cl−) concentration on the corrosion mechanism of WC–MgO composites has been studied in this work. The results suggest that the corrosion resistance of WC–MgO composite decreases first and then increases with the increase in
