Pitting corrosion of chloride ions and improvement measures
Thread Content
Since all metal materials contain non-metallic inclusions to varying degrees, these non-metallic compounds will rapidly lead to pitting corrosion under the corrosive action of Cl ions. Due to the effect of a closed cell, Cl ions outside the pits will migrate into the pits, while the positively charged metal ions inside the pits will migrate outward. In stainless steel materials, those with Mo added exhibit better resistance to pitting corrosion compared to those without Mo; the higher the Mo content, the better the resistance to pitting corrosion.
