Plaque d'usure plaquée: Structure and Typical Service Life of Hardfaced Wear Plates
Clad wear plate (also called weld overlay wear plate or hardfaced plate) is a composite material designed to resist severe abrasion and impact. It is produced by metallurgically bonding a hard wear-resistant layer onto a ductile steel base plate.
The performance of clad wear plate depends on its layered structure and the service conditions in which it operates.
1. Main Structure of Clad Wear Plate
| Couche | Fonction principale |
|---|---|
| Wear-resistant overlay layer | Provides hardness and abrasion resistance |
| Zone de transition (fusion layer) | Ensures metallurgical bonding between layers |
| Plaque de base en acier | Fournit de la ténacité, force, et soutien structurel |
Each layer plays a different role, and together they form a balanced wear protection system.
2. Wear-Resistant Layer Composition
The top wear layer is usually made of:
- Alliages de carbure de chrome (most common)
- Complex carbide systems (Cr-Nb-Mo)
- Tungsten carbide reinforced alloys
These hard phases provide resistance against abrasion, érosion, et usure par glissement.
3. Typical Service Life of Clad Wear Plate
Service life depends on material type, épaisseur, and working conditions. En général, clad wear plates significantly outperform ordinary steel.
| Working Condition | Expected Service Life Improvement |
|---|---|
| Light abrasion | 3–5× longer than mild steel |
| Medium abrasion | 5–8× longer |
| Forte abrasion (ciment, exploitation minière) | 8–12× longer |
| Conditions d'usure extrêmes | Up to 15× depending on design |
4. Factors Affecting Service Life
| Facteur | Influence |
|---|---|
| Carbide type | Determines hardness and wear resistance |
| Épaisseur de superposition | Controls usable wear life duration |
| Niveau d'impact | High impact reduces service life |
| Material flow type | Sliding wear is more severe than impact-only wear |
5. Why Clad Wear Plates Last Longer
- Hard carbide layer resists direct abrasion
- Ductile base absorbs impact energy
- Metallurgical bonding prevents delamination
- Layered structure balances hardness and toughness
6. Application Environments
| Industrie | Typical Equipment |
|---|---|
| Exploitation minière | Chutes, concasseurs, doublures |
| Ciment | Trémies, ducts, cyclones |
| Steel plants | Sinter systems, convoyeurs |
| Centrales électriques | Coal and ash handling systems |
