Hard chrome plating has excellent hardness with a hardness value of HV750 to 900, but it has the issue of cracks (fine fissures) in the coating, which means that no matter how much the surface is polished to a mirror finish, the cracks can transfer to the product. Our company has long had the technology for a non-crack chrome plating called "Cloamore." The hardness can reach up to HV1800 through heat treatment at temperatures of 200 to 600°C, and because it is non-crack, it also has excellent corrosion resistance. However, due to the limitation of being able to apply only a thin film with a thickness of up to 5μ, it has not been possible to apply it to mirror rolls until now. However, we have developed a technology for "super mirror crack-free rolls" that solves these problems by forming a special two-layer structure.

Chrome plating and Roll Navi is a site that provides information on the processing steps and physical properties of hard chrome plating, as well as surface treatment of machine parts focused on roll manufacturing. Additionally, it compiles basic knowledge about plating and specific case studies for problem-solving. If you have any issues regarding chrome plating or rolls, we hope you find this site helpful.
