Chrome-based surface treatment
BCr (black chrome) with excellent release properties, abrasion resistance, and high corrosion resistance.
The "chromium-based surface treatment" of the electrochemical membrane industry is superior to conventional hard chrome plating (Hv=700), which is why this Cr-C4 treatment is established as the standard treatment for "hard chrome plating." "BCr (black chrome)" has a uniform micro-crack (velvet-like) structure, achieving high corrosion resistance. Additionally, we have developed a low hexavalent BCr that complies with RoHS. 【Features】 ■ Forms a thin film of 2-3μm, suitable for precision parts ■ Due to the uniform micro-cracks, corrosion current is dispersed, providing high corrosion resistance ■ The velvet-like film serves as a pre-treatment for painting and coating parts ■ Implements work processes in accordance with MIL-DTL-14538D ■ Developed a low hexavalent BCr compliant with RoHS (removal of residual hexavalent chromium) *For more details, please refer to the catalog or feel free to contact us.
