WC-12Co HVOF/HVAF thermal spray powder Excellent abrasion resistance

DG.WC-12Co is a high-performance tungsten carbide (WC)-based thermal spray powder, mainly composed of 88% tungsten carbide and 12% cobalt. Its unique chemical composition and advanced production process (agglomeration sintering) enable it to perform well in various industrial applications. The powder has a bulk ratio of 4.4~5.2g/cm³ and a Vickers hardness range of 950~1350HV, showing extremely high hardness and wear resistance. It is suitable for a variety of thermal spray processes, including high-pressure oxygen fuel spraying (HVOF), high-pressure air fuel spraying (HVAF) and plasma spraying (APS). Its bonding strength exceeds 70MPa, the porosity is less than 1%, and the deposition rate is between 55% and 60%, ensuring the density and durability of the coating. The maximum operating temperature of the DG.WC-12Co coating can reach 500℃, allowing it to maintain excellent performance in high temperature environments.

product details

Performance characteristics

DG.WC-12Co’s coating has excellent performance and can provide the best surface protection for a variety of applications. Its excellent wear resistance, friction and wear resistance, and resistance to erosion and cavitation make it an ideal choice for the industrial sector. The coating has a smooth surface, fine microstructure, and high bonding strength, which can effectively extend the service life of equipment and reduce maintenance costs.

At medium temperatures, DG.WC-12Co coating can withstand working environments up to 500°C and is suitable for use in a variety of industrial conditions. Especially in the fields of oil and gas, steel production, etc., DG.WC-12Co coating can effectively resist wear, fretting wear, sliding wear and impact, ensuring the stable operation of equipment.

Typical Applications

DG.WC-12Co is widely used in many industries, especially in situations where high wear resistance and high temperature performance are required. The following are some typical applications:

General Industry: In various mechanical parts, DG.WC-12Co coating can provide excellent wear protection and is suitable for key components such as gears and bearings.

Oil and Gas: During drilling and mining, equipment often faces extreme wear and corrosion. DG.WC-12Co coating can effectively extend the service life of equipment and reduce downtime.

Steel production: In high temperature and high wear environments, DG.WC-12Co coating can protect process rollers, paper rolls, corrugated paper rolls and other equipment to ensure production efficiency.

Spraying processing: In the aviation field, DG.WC-12Co is suitable for spraying aviation fan and compressor blades, providing excellent wear resistance and corrosion resistance to ensure flight safety.

Notes

Although DG.WC-12Co performs well in many applications, it is not recommended for use in acidic environments. To achieve better corrosion resistance with comparable wear resistance, powders such as WC 10Co 4Cr or WC 20CrC 7Ni are recommended. These alternative materials offer improved performance in specific environments.

In Conclusion

DG.WC-12Co is an ideal thermal spray powder. With its excellent performance and wide application fields, it has become the preferred material in the industry. Whether in high temperature, high wear environment, or in applications requiring high corrosion resistance, DG.WC-12Co can provide reliable solutions to help companies improve production efficiency and reduce operating costs. Choosing DG.WC-12Co, you will get excellent surface protection and lasting performance guarantee.
