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. The thickness of hard chromium plating is generally 5-50μm, and can also be determined according to needs, and some are as high as 200-800μm. 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.
