High-Performance WC-10Co4Cr Thermal Spray Powder Suppliers in China - Factory Direct Abrasion Resistance Solutions
Basic Parameters
Chemical Composition & Process
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.
Thermal Spraying Performance
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. The bonding strength exceeds 70MPa, the porosity is less than 0.8%, and the deposition rate is between 48% and 55%, showing its excellent coating quality.
Product Performance
Key Characteristics
The performance characteristics of DG.WC-10Co4Cr make it widely applicable in industrial applications. First, its wear and corrosion resistance are very good, and it can maintain good performance in harsh environments. Secondly, the high bonding strength of the coating ensures a strong bond between the coating and the substrate, avoiding the risk of coating peeling. In addition, the material also has high impact toughness and can withstand large impact forces, making it suitable for occasions with high impact loads.
