Chrome Oxide Ceramic Coatings (Cr2O3 Coatings)

Chrome Oxide Plasma Spray

Food Processing Impeller Shaft Ceramic Coated Seal Surfaces

Chromium oxide (Cr203) ceramic coatings are a type of industrial coating applied using flame spray or plasma electric arc coating services. Cr203 coatings are highly effective for providing seal surfaces, improving abrasion, and enhancing wear resistance. Due to the color, they are often referred to as green or black oxide coatings.

At Hannecard – ASB, we provide cost-effective turnkey black oxide ceramic coating services that allow your projects to be customized to meet your requirements. We serve a variety of industries, including power, steel, paper, and many more. We are proud to be your trusted provider of advanced chromium oxide coating services. Contact us or call 330-551-5217 for more information regarding our industrial Cr203 coating services and finishing options or to discuss your specific project requirements.

Benefits & Features of Black Oxide Coatings

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

• Excellent wear resistance
• Excellent abrasion resistance
• High chemical resistance
• Anti-reflective finish

Cr203 Coating Processes & Services

Plasma-sprayed chromium oxide coatings are the perfect choice for industrial applications that require self-mating abilities, anti-galling properties, and high corrosion resistance. Ideal candidates for this material include parts affected by wear from cavitation, particle erosion, hard surfaces, and abrasive grains. Our chrome oxide coatings are custom-tailored to your application’s specific requirements using our custom coating services:

• Plasma Electric Arc
• Powder Feedstock
• Powder Combustion Thermal Spray
• Ceramic-Based Feedstock

Applications for Chromium Oxide Coatings

Chrome oxide ceramic coatings are useful in a wide range of industrial applications due to the material’s density, hardness, and many other advantages.

Common Applications for Chrome Oxide Ceramic Coatings

• Sealing surfaces on food processing equipment
• Enhancing different types of seals
• Improving abrasion and wear resistance

Additionally, chrome oxide ceramic coatings are typically applied to pump components, rotating equipment, and other parts requiring an increased resistance to wear or chemicals.

Industries that May Utilize Cr203 Coating Services

• Power Generation
• Original Equipment Design and Engineering
• Steel Making and Processing
• Paper Making including Recycle

Chromium Oxide Coating Pre-Machining & Post-Finishing Services

Hannecard – ASB understands that every coating project is different, and we work hard to customize our services to your exact order. Using diamond grinding wheels and belts, we provide pre-machining and post-finishing services to OE dimensions for our chrome oxide coatings. Diamond grinding achieves smooth, polished surfaces on Cr203 while maintaining a low coefficient of friction.

Specialty chemistries are also available to meet unique needs and could include fused and crushed mixtures, cladded oxide with titanium additives, or others.
