China WC-10Co4Cr HVOF/HVAF Thermal Spray Powder Suppliers | Factory for Excellent Abrasion Resistance Coatings
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. 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
The performance characteristics of DG.WC-10Co4Cr make it widely applicable in industrial applications. Key highlights include:
- Excellent wear and corrosion resistance: Maintains reliable performance even in harsh operating environments.
- High bonding strength: Ensures a strong bond between the coating and the substrate, effectively avoiding the risk of coating peeling.
- High impact toughness: Capable of withstanding large impact forces, making it suitable for high impact load applications.
- Outstanding sliding wear resistance: Ideal for parts requiring frequent friction, such as valve seats, various rollers, and compressor blades.
- High production efficiency: The high deposition rate allows the coating to be completed in a relatively short timeframe.
