The crevice corrosion of metal material is a kind of local corrosion, when there are cracks or metal and other objects for metal material
Between crevice corrosion will occur when forming narrow gap, stitched when research shows that especially gap width being 0.05~0.15mm
Gap corrosion susceptibility highest.According to simulating occluded corrosion cell principle, the convection current and diffusion hindered of inside and outside solution are stitched, causes block section poor
Oxygen, it is still oxygen-enriched outside gap, caused by oxygen concentration cell make the current potential of metal in gap lower than the current potential of metal outside gap, pH value
Reduction and H+And Cl-So that metal is in the state of activation with (HCl), promote the dissolution of metal in block section, forms two in sealing
Secondary corrosion product Fe (OH)3, cause positive excess, Cl-It moves into.And chloride hydrolyzes in water, makes medium (H in gap+Increase from concentration) it is acidified, therefore pH value decline, accelerates the dissolution of anode.The acceleration of anode is dissolved, and causes more Cl-
