A hydrated oxide layer is formed inside the micropores and in the upper 5μm thickness! It has excellent alkali resistance!
We would like to introduce the "Kawamite processing" that we conduct. The characteristics of Kawamite include a dense layer on the surface of the coating that is 1 to 10 μm thick, providing excellent alkali corrosion resistance. It has excellent sealing properties, and in the phosphoric acid-chromic acid solution immersion test, there was no mass loss. 【Features】 ■ Excellent alkali resistance ■ Superior sealing properties with no mass loss ■ Excellent breakdown voltage ■ Dense layer on the surface of the coating is 1 to 10 μm ■ A hydrated oxide layer is formed within the fine pores and in the upper layer, which is 5 μm thick *For more details, please refer to the related links or feel free to contact us.
