Hard Chrome Plating

Hard chrome plating, also known as functional chrome plating or hard chrome, is an electrochemical process used to deposit a layer of chrome onto a base material. It is employed in applications where high hardness, abrasion resistance, and improved corrosion resistance are primarily required. One of the advantages of hard chrome plating is the ability to apply thick layers, making it often used for the refurbishment of worn parts.
The technology used in hard chrome plating is a modern process that includes a sulfate and organic catalyst without fluoride content. Chrome coatings produced by this process have a micro-cracked structure and exhibit higher corrosion resistance, hardness, and abrasion resistance compared to conventional processes.

Technical Parameters

  • Hardness of at least 1000 HV (69 HRc) 
  • Abrasion resistance 5-6 TWI 
  • Good corrosion resistance
  • Lubricity: static coefficient of friction with steel 0.19 
  • Non-adherent surface

  • Technology characteristics 

  • Hard chrome plating offers very high hardness, abrasion resistance, and good anti-corrosion properties. Additionally, components plated with hard chrome gain good lubrication properties and non-adherence to rubber compounds through functional chrome plating. Due to these properties, hard chrome plating is used in numerous applications, such as in the automotive, aerospace, and rubber industries, for plating cylinders, shafts, molds, bearings, valves, and many other components. It complies with standards like ISO 6158, MIL-STD-1501, AMS 2406, and AMS 2460.
