By adding high corrosion-resistant metal compounds to conventional passivation solutions, it is possible to create a surface that is more resistant to rust.
We would like to introduce the passivation technology known as "P-max treatment (Passivate max)." This technology involves performing electrolytic polishing as a pre-treatment to dissolve and remove the altered layer caused by buff polishing and machining, while also modifying the outermost surface to create a chromium-rich layer with a chromium to iron content ratio of 1.6:1 or higher. Furthermore, after enhancing corrosion resistance through electrolytic polishing, the material is immersed in a special passivation solution to generate a more stable and dense oxide film, while also incorporating highly corrosion-resistant metal compounds within that film. 【Features】 ■ High pitting corrosion resistance ■ Pitting corrosion potential ranges from 800 mV to 1000 mV ■ High corrosion resistance and cleanliness ■ High leaching resistance ■ Highly corrosion-resistant metal compounds are incorporated within the passivation film *For more details, please refer to the PDF document or feel free to contact us.
