Appropriate for applications 1000- 1500°F, coatings of chrome carbide nickel chrome are recommended for resistance wear by abrasion, hard surfaces, fretting, and particle erosion.

Chrome carbide coatings are used for wear resistance in combination with a higher temperature capability than is possible with tungsten carbide powders. Although generally less wear resistant than tungsten carbides, chrome carbide is excellent at higher temperatures and under corrosion and oxidation conditions. These properties are enhanced when the metal alloy matrix is made from the highly corrosion resistant Nichrome alloy.
