マルイ鍍金工業 List of Products and Services

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.

At Marui Plating Industry Co., we conduct on-site construction work at the location (equipment manufacturers and end users). We accommodate a variety of products, from small items to large ones. 【Features】 ○ On-site acid cleaning work Similar to immersion acid cleaning, a special acid cleaning agent is applied overall. It is less likely to cause unevenness, and since it is not a brush application method, there are no brush marks. ○ On-site cleaning work - Alkaline degreasing cleaning Removal of oils and fats. Electrolytic degreasing is also possible. - Pure water cleaning After degreasing and other cleaning processes, pure water is used for more precise cleaning. - Passivation treatment Corrosion resistance is improved after degreasing cleaning. ○ On-site electrolytic polishing ● For other functions and details, please download the catalog.
