Spray coating processing SPRAY PROCESSING
Spray-on repair for worn areas of fan impeller blades
Our company provides repair services for worn areas on fan impellers in cement plants, power plants, and other facilities, as well as surface enhancement coatings for new impellers, which can extend the service life of impellers by several times. We employ a supersonic thermal spraying technique using tungsten carbide coatings, resulting in dense coatings with high hardness and excellent wear resistance, thereby significantly prolonging the service life of components. Tungsten carbide powder coatings—Tungsten carbide (WC) is the primary raw material used in the production of cemented carbides and boasts exceptionally high microhardness. Commonly used WC-based powder coatings include WC 8% Co, WC 12% Co, and WC 17% Co. The addition of cobalt in varying proportions to WC primarily serves as a binder, enhancing the toughness of the coating while preventing excessive carbon burn-off during the spraying process. Chromium carbide (Cr2C3) features high hardness and exhibits excellent resistance to high-temperature oxidation and wear, with a maximum operating temperature of up to 800°C. Typically, Cr2C3 is mixed with Ni-Cr alloys and is mainly applied to high-temperature wear-prone areas. Mechanical component wear-repair coating process using tungsten carbide—tungsten carbide wear-resistant coating parameters: Processing steps: → Sandblasting → Preheating → Primer application → Tungsten carbide spraying (thickness: 0.04–1.0 mm) → Grinding; Processing methods: Plasma or supersonic flame spraying. Tungsten carbide coating performance indicators: Hardness: Up to HRC 70–80; Bonding strength: ≥90 MPa; High-temperature resistance: Above 1200°C; Coating thickness: 0.04 mm–1.0 mm; Service life: 3–6 times longer than that achieved by conventional methods. Processing range: Diameter—from tens of millimeters to hundreds of millimeters; Length—from several millimeters to several meters.
