Spray coating processing SPRAY PROCESSING
Tungsten carbide coating on the surface of the paper machine rewind roller.
The defects—such as wear, scratches, and scoring—on various rollers used in paper-making machinery are major factors that limit paper quality. For stone rollers that operate at high speeds and frequently, steel rollers can be coated with oxide ceramics or metal-composite ceramic materials via thermal spraying, effectively replacing traditional stone rollers in paper machines without being constrained by frequent, high-speed operation. Similarly, issues like adhesive wear on machine calendering rollers and doctor blades, corrosion of water-conditioning rings, degradation of surface smoothness on glossy calendering rollers, and mechanical wear on nip rollers, sizing rollers, post-drying rollers, and winding drums—all these problems can be addressed through advanced thermal-spraying technologies. At the same time, this approach can extend the service life of paper-machine components by several times. For example, carbide coatings applied to re-winding rollers in paper machines, mirror-finish rollers, and other paper-machine components—including rollers, drying cylinders, and stock chests—operate under conditions of metallic-to-metal wear. Our solution involves supersonic spraying of WC/C0/316L, followed by polishing to achieve a mirror-like finish. The technical specifications are as follows: coating thickness 70–120 μm, surface roughness Ra 3.5–6.5, and coating adhesion strength ≥55 MPa. As for molybdenum rollers used in papermaking, which experience material abrasion and media corrosion, our solution is supersonic spraying of WC/C0/Cr, combined with flame-spraying of metallic molybdenum materials or arc-spraying of corrosion-resistant alloy materials. We have accumulated extensive experience in coating applications and are now successfully replicating these proven cases. We will guide you through the entire coating-manufacturing transition process, ensuring: rapid start-up; a reliable supply solution covering all aspects—from materials and equipment to processes; coating trials conducted either on-site at your facility or at our technical center; and consistently high-quality, efficient coatings.

Tungsten carbide coating on the surface of the paper machine rewind roller.
Defects such as wear, scratches, and scrapes on various rollers used in papermaking machinery are major factors that constrain paper quality. For stone rollers that operate at high speeds and frequent cycles, steel rollers can be coated with oxide ceramics or metal-composite ceramic materials, effectively replacing traditional stone rollers in paper machines without being limited by frequent, high-speed operation. Similarly, issues like adhesive wear on machine calendering rollers and doctor blades, corrosion of water-conditioning rings, degradation of surface smoothness on glossy calendering rollers, and mechanical wear on nip rollers, sizing rollers, post-drying rollers, and winding drums can all be addressed through thermal spraying technology. At the same time, this technology can extend the service life of papermaking machinery components by several times.
