Abstract
Increasing dissolved oxygen (DO) concentration of saturated Ca(OH)2 solution accelerated formation of corrosion resistant film, calcium hydroxy zincate (Ca(Zn(OH)3)2·2H2O, CHZ) on zinc and increased the density of the CHZ layer. The increase in the DO concentration enhanced the oxygen reduction reaction, which is the rate-determining step of the CHZ formation. The higher the DO concentration of the saturated Ca(OH)2 solution, the shorter the period for the improvement of corrosion resistance of zinc. This is because the accelerated formation of insulating CHZ rapidly reduced the exposed metal surface of zinc.
