Tungsten carbide coatings are primarily made of carbide metal ceramics.

Materials mainly include: WC-Co, WC-10Co-4Cr, WC-NiCr, Cr3C2-NiCr, etc.

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

Application Direction:

1. Various roller types in the metallurgy industry, such as return furnace rollers, galvanized rollers, tension rollers, 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. Draw Tower, Draw Barrel, Spooling Reel, Tension Wheel, Guide Groove, etc. for the Metal Wire Drawing Industry

4. Piston rods, plungers, shafts, valve balls (valve cores), valve seats, valve plates, valve stems, impellers, mechanical seals, thread cutting blades, curling rolls, etc. for the machinery manufacturing industry

5. Molds for other applications, coal mill (pulverizing mill) blades, water-cooled walls, ultra-fine powder, kneading chambers, and kneading machine rotors

Coating Material:

WC-Co: Ultra-high hardness, excellent wear resistance

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

WC-NiCr: Dense coating, high hardness, strong toughness, excellent corrosion resistance to organic acids and alkalis, wear resistance

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