Pelat Keausan Berpakaian: 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
| Lapisan | Fungsi Utama |
|---|---|
| Wear-resistant overlay layer | Provides hardness and abrasion resistance |
| Transition zone (fusion layer) | Ensures metallurgical bonding between layers |
| Pelat baja dasar | Provides toughness, kekuatan, and structural support |
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:
- Chromium carbide alloys (most common)
- Complex carbide systems (Cr-Nb-Mo)
- Tungsten carbide reinforced alloys
These hard phases provide resistance against abrasion, erosi, dan keausan geser.
3. Typical Service Life of Clad Wear Plate
Service life depends on material type, ketebalan, and working conditions. Umumnya, clad wear plates significantly outperform ordinary steel.
| Kondisi Kerja | Expected Service Life Improvement |
|---|---|
| Light abrasion | 3–5× longer than mild steel |
| Medium abrasion | 5–8× longer |
| Abrasi parah (semen, pertambangan) | 8–12× longer |
| Kondisi keausan ekstrem | Up to 15× depending on design |
4. Factors Affecting Service Life
| Faktor | Influence |
|---|---|
| Carbide type | Determines hardness and wear resistance |
| Ketebalan lapisan | Controls usable wear life duration |
| Tingkat dampak | 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
| Industri | Typical Equipment |
|---|---|
| Pertambangan | peluncuran, penghancur, liner |
| Semen | gerbong, ducts, siklon |
| Pabrik baja | Sinter systems, konveyor |
| Pembangkit listrik | Coal and ash handling systems |
