Hard chromium plating (abrasion-resistant chromium) The plating layer has extremely high hardness and wear resistance, which can extend the service life of workpieces, such as cutting and drawing tools, pressing molds and casting molds of various materials, bearings, shafts, gauges, gears, etc., It can also be used to repair the dimensional tolerances of worn parts. Hard chromium plating thickness is . 5 ~ 50 m , it may be determined according to need, some as high as 200 is ~ 800 m . Hard chromium plating of steel parts does not require intermediate coating. If there are special requirements for corrosion resistance, different intermediate coatings can also be used.
