Prevent "galling and seizure" caused by intermetallic friction! The fit is perfect and the accuracy is within ±10%!
Our company is capable of applying a special plating called "Kanizen Plating" depending on the intended use. The adhesion strength on soft steel is 24 kg/mm², which is approximately 2.5 times that of hard chrome (9 kg/mm²). It prevents "galling and seizing" caused by intermetallic friction with metals such as titanium and 18-8 stainless steel. Additionally, the hardness is Hv500 in the as-plated state and up to 1000 Hv in the heat-treated state. 【Features】 ■ Chemical composition: -Ni 90-92%, P 8-10%, making it excellent in corrosion resistance. ■ Wear resistance: Significantly better than electroplating in the plated state. ■ Adhesion: The adhesion strength on soft steel is 24 kg/mm², about 2.5 times that of hard chrome. ■ Abrasion resistance: Prevents "galling and seizing" due to intermetallic friction. ■ Uniformity: The coating is complete, and its precision is within ±10% of the required thickness. ■ Hardness: Hv500 in the as-plated state, up to 1000 Hv in the heat-treated state. *For more details, please refer to the PDF document or feel free to contact us.
