Introduction to Tungsten Carbide Coating Process

Tungsten carbide (WC) is a material with extremely high hardness and wear resistance. The spraying process involves propelling it in the form of small particles onto the substrate surface with gas to form a protective coating. Due to its excellent mechanical properties, tungsten carbide spraying is widely used in surface treatment of mechanical components such as pumps, valves, molds, rollers, and blades.

To ensure the ideal performance of tungsten carbide coatings, relevant industries and standard organizations have formulated multiple spraying standards and technical requirements. Generally, the thickness of tungsten carbide coatings should be controlled between 100-300 microns, depending on the operating environment and the application requirements of the workpiece. Tungsten carbide spraying technology has the advantages of good thermal stability, excellent wear resistance, superior impact resistance, and good machinability, but it is higher in cost and requires stricter construction conditions.

Tungsten carbide spraying is widely used in manufacturing, aerospace, energy, automotive, and other fields, especially in tools, molds, and hydraulic components, significantly enhancing their wear resistance, service life, and mechanical component performance.
