Arc Tungsten Carbide (Arc TC) is a highly effective material for wear lining applications, particularly in industries where abrasion, impact, and corrosion resistance are critical. Here are the key advantages of choosing Arc Tungsten Carbide for wear lining:
1. Exceptional Wear Resistance
- Tungsten carbide is one of the hardest materials available (HV 1500-2000), making it highly resistant to abrasive wear.
- Outperforms traditional materials like chrome steel, ceramic tiles, and even some other hardfacing alloys in high-wear environments.
2. Superior Impact Resistance
- Unlike brittle alternatives (e.g., pure ceramics), Arc TC combines tungsten carbide particles with a tough metallic matrix (typically cobalt or nickel-based), providing excellent resistance to chipping and cracking under impact.
- Ideal for applications involving heavy impact, such as mining, mineral processing, and bulk material handling.
3. Corrosion & Chemical Resistance
- The binder matrix (especially nickel-chromium variants) enhances corrosion resistance, making it suitable for wet or chemically aggressive environments.
- Performs well in slurry pipelines, dredging, and chemical processing equipment.
4. Extended Service Life
- Arc TC linings can last 3–10 times longer than conventional steel or ceramic linings, reducing downtime and replacement costs.
- Lowers total cost of ownership (TCO) despite a higher initial investment.
5. Customizable Application Methods
- Can be applied via welding (arc overlay), thermal spray, or as prefabricated tiles/plates, offering flexibility for different equipment geometries.
- Suitable for complex shapes like chutes, hoppers, cyclones, and pump casings.
6. High Temperature Stability
- Maintains hardness and wear resistance at elevated temperatures (up to ~600°C), unlike polymers or some metals that degrade.
7. Reduced Maintenance & Downtime
- Longevity and durability minimize frequent shutdowns for lining replacements, improving operational efficiency.
8. Improved Flow Characteristics
- Smooth, hard surfaces reduce material buildup (e.g., coal, ore, cement), enhancing flow efficiency in conveyors and transfer points.
Typical Applications:
- Mining & Quarrying (crushers, screens, excavator buckets)
- Cement & Power Plants (raw mill liners, cyclone separators)
- Oil & Gas (drilling tools, slurry valves)
- Dredging & Sand Processing (pump housings, pipelines)
