After the treatment of oxidizing medium, its corrosion rate than before the original treatment has a significant decline in the phenomenon called the metal passivation. The passivation mechanism can be explained by the thin film theory, that is, the passivation is due to the interaction between the metal and the oxidizing medium, and a very thin, dense, well-covered passivation film can be strongly attached to the metal surface during the action.
This membrane exists as a separate phase, usually a compound of oxygen and metal. It plays the role of completely separating the metal and corrosive medium, prevent the direct contact between the metal and corrosive medium, so that the metal basically stops dissolving and forms blunt to achieve the effect of preventing corrosion.
KEMON stainless steel passivation solution ID3000-1 is suitable for austenitic stainless steel and duplex stainless steel natural passivation treatment. New catalytic technology is adopted, so the product passivates faster and has stronger corrosion resistance. Through this product passivation, can form a dense passivation protective film in 5-15 minutes, while maintaining the original luster of the workpiece, do not damage the size of the workpiece, the performance of the neutral salt spray has been more improved.
