Chromium Oxide Coating Features

Chrome oxide (Cr2O3) is an inorganic compound of chromium and oxygen. It is one of the principal oxides of chromium and occurs naturally as the rare mineral eskolaite. Chromium oxide coatings (Cr2O3 coatings) impart many of the material’s favorable characteristics to coated substrates, including:

  • Excellent Wear
  • Excellent Abrasion Resistance
  • High Chemical Resistance
  • Anti-Reflective

Chrome Oxide Ceramic Coating Processes

If you are looking for plasma spray coatings that provide excellent self-mating, anti-galling and corrosion resistant properties, plasma sprayed chromium oxide coatings are the perfect choice. Parts that are affected by wear problems caused by cavitation, particle erosion, hard surfaces and abrasive grains are excellent candidates for this material. Our chrome oxide coatings are custom-tailored to your application’s specific requirements using our custom coating processes, which include:

Chromium Oxide Cr2O3 Coating Applications

Due to its color chrome oxide is often referred to as a green or black oxide coating. Chrome oxide ceramic coatings are useful in a wide range of additional industrial applications, including:


  • Sealing surfaces on food processing equipment
  • Enhancing different types of seals
  • Improving abrasion and wear resistance
  • Bearing protection from long wearing surfaces

Industries Served

  • Automotive
  • Construction
  • Energy
  • Military
  • OEM
  • Steel
  • Paper

Additionally, chrome oxide coatings are commonly applied to pump components, rotating equipment, and other parts and components to improve wear resistance and chemical resistance.

Chromium Oxide Coating Pre-Machining & Post Finishing Services

Hannecard - ASB provides pre-machining and post finishing to OE dimensions for our chrome oxide coatings, using diamond grinding wheels and diamond belts. Diamond grinding achieves smooth, polished surfaces on Cr2O3, with a low coefficient of friction.

In addition, specialty chemistries, including fused and crushed mixtures or cladded oxide with titanium dioxide additives, are also available to meet unique needs.
