Tungsten carbide coatings are primarily made of carbide metal ceramics.

Materials primarily used include WC-Co, WC-10Co-4Cr, WC-NiCr, and Cr3C2-NiCr metal-ceramics.

Tungsten carbide coatings feature dense coatings, low porosity, high bonding strength, high hardness, good toughness, and resistance to high temperatures.

Application Direction:

1. Various rolling mill products in the metallurgy industry, such as return furnace rolls, galvanized rolls, tension rolls, shafts, and fan blades.

2. Calender rolls, coating rolls, corrugating rolls, drying cylinders, winding rolls, cutting tools, ink rolls, printing rolls, etc. for the paper and printing industry

3. Wire Drawing Industry: Drawbench, drawing tank, winding reel, tension wheel, guide groove, etc.

4. Piston rods, plungers, shafts, valve balls (valve cores), valve seats, valve plates, valve stems, impellers, mechanical seals, wire bundle cutting blades, and crimping rollers for the mechanical manufacturing industry.

5. Moldings for other applications, coal mill (pulverizer) blades, water-cooled walls, ultra-fine powder, compaction chambers, and compaction mill rotors

Coating Material:

WC-Co: Superior ultra-high hardness and wear resistance

WC-10Co-4Cr: Corrosion and erosion resistant, micro-vibration and abrasive wear resistance

3. WC-NiCr: Dense coating, high hardness, strong toughness, excellent corrosion resistance to organic acids and alkaline solutions, and good wear resistance

4. Cr3C2-NiCr: High-temperature wear and erosion resistance, as well as gas corrosion resistance, especially in chlorine, acidic, and alkaline environments; resistant to solid particle and sliding wear
