Tungsten Carbide Coating
Tungsten chromium carbide coatings our coating formulations have been designed for optimal effectiveness with our thermal spray application process.
Tungsten carbide coating. Wc is a chemical compound specifically a carbide containing equal parts of tungsten and carbon atoms. The process of thermal spraying allows coating companies to choose the most appropriate material to be used for applications thereby assuring production on a consistent level. Carbide coatings are typically used for wear resistance to abrasion erosion galling and fretting. This high bond strength far surpasses any spray on coating currently available.
In its most basic form tungsten carbide is a fine gray powder but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery cutting tools abrasives armor piercing shells and jewellery. Plasma sprayed carbide coatings may be selected to achieve a higher texture as sprayed. Our winning carbidex coating formulations combine tungsten carbide and carefully selected alloys or metals to provide the most economical wear solution available. Thus tungsten carbide coatings and ceramic coatings are particularly effective in conditions of extreme wear.
Tungsten carbide powder or another powder coating material as your project requires is injected into the nozzle where the particles mix with the speeding gases reaching velocities up to 3 000 feet per second. Carbinite is a tungsten carbide or stellite carbide alloy that can be applied to most metals using a process called electro spark deposition esd yielding a true metallurgical bond. Hvof tungsten carbide coatings are often applied to roll surfaces used in paper production. Tungsten carbide materials are recommended for wear applications with service temperatures of less than 500 degrees celsius as higher temperatures will result in the formation of brittle phases that reduce wear resistance and coating integrity.
In these challenging environments erosion abrasion and corrosion are some of the most common issues. Tungsten carbide and chrome carbide are the predominant carbide materials used to apply protective surfacing using thermal spray processing techniques. Hvof tungsten carbide thermal spray equipment. The tungsten carbide wc 12co coatings are resistant to sliding wear impact abrasion and fretting at temperatures up to 510 c 950 f preferably in non corrosive media.
Relatively thin layers of carbide coatings can offer dramatic protection against abrasion galling fretting and erosion. We recommend chromium carbide coatings for higher temperature applications. Tungsten carbide chemical formula.
