WC/Co/Cr Coatings: A Versatile Solution

• Enhanced Mechanical Properties:  Cobalt serves as a binder, enhancing toughness and adhesion, while chromium imparts additional corrosion resistance.
• Superior Corrosion Resistance: WC/Co/Cr coatings offer corrosion resistance, making them ideal for applications in aggressive environments.
• High-Temperature Stability: These coatings can withstand elevated temperatures (up to 250°C/480°F) without significant degradation, rendering them suitable for applications in hot environments, such as gas turbines and exhaust systems.
• Low Friction Coefficient: WC/Co/Cr coatings exhibit a low coefficient of friction, reducing wear and improving efficiency in moving parts.

of WC/Co/Cr and WC/Co Coatings

• Aerospace: Compressor components, and seals
• Automotive: Aluminum wheels
• Oil and Gas: Valves (gate and ball), pump components, and Drilling tools
