The main application scenarios of thermal sprayingThe main application scenarios of thermal spraying

Thermal spraying can solve the problems of wear, corrosion, and high temperature of the workpiece under complex working conditions through customized coating design, and is a widely used surface strengthening technology in the industrial field. If a specific solution is required, the process and material should be selected comprehensively based on the workpiece material, working condition environment and cost budget.

Enhance surface properties

• Abrasion resistance: Spraying tungsten carbide (WC-Co), chromium carbide (Cr3C2-NiCr) and other high-hardness materials can greatly improve the hardness of the workpiece surface and reduce wear (such as gears, hydraulic rods).
• Corrosion resistance: Sprayed with nickel-based alloys (e.g., Inconel 625), cobalt-based alloys (e.g., Stellite 6) or ceramic coatings (e.g., Al₂O₃-TiO₂) to resist corrosive environments such as acids, alkalis, salt spray (e.g., chemical pumps, ship components).

Repair worn or corroded workpieces

• Spray and repair worn shafts, molds, hydraulic cylinders and other components to restore dimensional accuracy and extend service life, at a much lower cost than replacing new parts.
