High-Performance WC-10Co4Cr Thermal Spray Powder from China Suppliers - Factory Direct for Abrasion Resistance
Basic parameters
The chemical composition of DG.WC-10Co4Cr is 9.5% carbon, 10% cobalt, 4% chromium and the balance tungsten. This combination not only improves the hardness of the coating, but also enhances its wear and corrosion resistance. The powder is produced using agglomeration sintering process, which ensures its uniformity and stability. Its Vickers hardness ranges between 1200 and 1400 HV, showing its excellent hardness characteristics.
In terms of thermal spraying process, DG.WC-10Co4Cr is suitable for a variety of processes such as high temperature flame spraying (HVOF), high pressure air flame spraying (HVAF) and plasma spraying (APS). These processes can effectively deposit the powder coating onto the substrate surface to form a strong coating.
Excellent coating quality is achieved through optimized material characteristics and precise thermal spraying deposition processes.
