Chrome Carbide Coatings

Chrome carbide coatings are a type of industrial coating. These coatings are usually applied via HVOF (High Velocity Oxygen Fuel) or plasma electric arc spray processes. Chrome carbide coatings are effective in operating temperatures as high as 1500°F (815°C). This material is proven to effectively resist wear caused by abrasion, fretting, particle erosion, and hard surfaces.

Chrome carbide coatings provide a number of performance enhancing benefits, most notably high wear resistance in high temperature environments; in this capacity, it can be used as a substitute for tungsten carbide. When combined with a nickel/chrome binder chemistry, it exhibits exceptional heat and oxide resistance in corrosive or oxidizing environments, even at extremely high temperatures. Adding a nichrome alloy to the coatings matrix provides even greater corrosion resistance.

Chemistries

Chrome carbide is a ceramic compound that exists in several different chemistries. The most durable of these chemistries, Cr3C2, has an orthorhombic crystal structure and a microhardness of 2280 kg/mm², making it the most common choice for surface treatments such as chrome carbide coatings. Chrome carbide’s chemistry can be altered to better suit the application for which they are being applied. As mentioned above, a range of additives can be combined with chrome carbide to enhance its beneficial characteristics.
