China WC-12Co HVOF/HVAF Thermal Spray Powder Factory - Superior Abrasion Resistance from Leading Suppliers

DG.WC-12Co is a premium thermal spray powder available from leading suppliers in China. Composed of 88% tungsten carbide and 12% cobalt, this high-performance powder excels in various industrial applications. Utilizing an advanced production process known as agglomeration sintering, DG.WC-12Co offers a bulk density of 4.4~5.2g/cm³ and Vickers hardness between 950 and 1350HV, which guarantees exceptional hardness and wear resistance. This versatile powder is compatible with multiple thermal spray techniques, including high-pressure oxygen fuel spraying (HVOF), high-pressure air fuel spraying (HVAF), and plasma spraying (APS). With a bonding strength exceeding 70MPa, less than 1% porosity, and a deposition rate of 55% to 60%, DG.WC-12Co ensures durable and dense coatings. Additionally, the coating can withstand operating temperatures up to 500℃, maintaining outstanding performance in high-temperature environments. Sourced directly from factory production in China, DG.WC-12Co is the ideal choice for industrial applications requiring top-quality thermal spray solutions.

    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.
