Further improve the hardness and corrosion resistance of hard chrome plating with micro-crack plating!
Typically, hard chrome plating is performed using a bath made of anhydrous chromic acid and sulfuric acid, referred to as a "Sargent bath," dissolved in water. Its hardness ranges from HV750 to 900, which is quite excellent, but even so, under harsh usage conditions, wear of the plating is unavoidable. Additionally, the cracks (fine fissures) present in the hard chrome plating layer can expand when heat is applied, which can be problematic depending on the application. However, our company has developed "CRO-FINE," which solves these issues by improving the components of the plating bath. 【Features】 ■ Hardness is excellent at HV950 to 1000 ■ Compared to typical hard chrome plating, the extent of crack expansion due to heating is smaller ■ Although there are many cracks, they are narrow and shallow, resulting in minimal penetration to the substrate and excellent corrosion resistance ■ Not only is it excellent in wear resistance, but it also reduces the wear amount of the opposing material *For more details, please refer to the related links or feel free to contact us.
