Tungsten Carbide Overlay Plate: Material Composition and Performance

Tungsten carbide overlay plate is a premium-grade hardfaced wear plate designed for extremely severe abrasion, erosion, and high-impact wear conditions. Compared with standard chromium carbide overlay plates, tungsten carbide overlay plates provide much higher hardness and superior wear resistance, especially in applications involving fine abrasive particles or high-speed material flow.

This type of wear plate is widely used in mining, oil sands, dredging, cement, and heavy industrial applications where traditional wear-resistant steel is insufficient.

1. Structure of Tungsten Carbide Overlay Plate

Layer	Main Function
Tungsten carbide overlay layer	Main wear-resistant working surface
Base plate	Provides strength, toughness, and weldability

The overlay layer contains extremely hard tungsten carbide particles embedded in a metallic alloy matrix.

2. Typical Chemical Composition of Overlay Layer

Material Component	Typical Range	Function
Tungsten Carbide (WC)	40–70%	Main ultra-hard wear-resistant phase
Tungsten (W)	Major alloy element	Improves hardness and wear life
Carbon (C)	Required for carbide formation	Forms WC structure
Iron / Nickel Matrix	Balance	Supports carbide particles and absorbs impact

3. Key Performance Characteristics

Property	Performance
Overlay hardness	HRC 70+ (much higher than chromium carbide)
Abrasion resistance	Extremely high
Erosion resistance	Excellent
Impact resistance	Moderate (depends on matrix design)
Service life	Significantly longer in severe wear conditions

4. Why Tungsten Carbide Overlay Performs Better

Ultra-high hardness: Much harder than chromium carbide overlays
Excellent particle wear resistance: Ideal for fine abrasive materials
Superior erosion protection: Performs well under high-speed wear
Long service life: Reduces maintenance and downtime significantly

5. Tungsten Carbide Overlay vs Chromium Carbide Overlay

Property	Tungsten Carbide Overlay	Chromium Carbide Overlay
Hardness	Higher	Lower
Abrasion resistance	Excellent	Very good
Impact toughness	Moderate	Better
Best application	Extreme abrasion / erosion	General heavy abrasion

6. Common Applications

Industry	Application
Mining	Slurry pipes, chutes, crusher liners
Dredging	Pump components, dredge pipes
Cement	High-wear transfer systems
Oil sands	Extreme abrasion equipment
