硬面板: Types of Hardfacing Layers Used in Wear-Resistant Steel Plates
Hardfaced plate is a composite wear-resistant steel product manufactured by depositing a hard alloy layer onto a carbon steel or low-alloy steel base plate. The performance of the plate is mainly determined by the type of hardfacing layer, which controls hardness, 耐磨性, 抗冲击性, 和使用寿命.
Different welding overlay systems are selected based on working conditions such as abrasion, 影响, 温度, 和腐蚀.
1. Main Types of Hardfacing Layers
| Hardfacing Type | Main Composition | 主要特点 |
|---|---|---|
| 碳化铬堆焊层 | 铁 + C + 铬 (high chromium carbides) | 优异的耐磨性, most common type |
| Complex carbide overlay | 铬 + 铌 + 莫 + C | Higher toughness and improved wear resistance balance |
| 碳化钨堆焊层 | 厕所 + Ni/Fe matrix | 极高的硬度, best for severe abrasion |
| Nickel-based overlay | 在 + 铬 + 乙 + 和 | Excellent corrosion and high-temperature resistance |
| Manganese-based overlay | High Mn + C alloy | Work hardening under impact conditions |
2. Performance Comparison of Different Overlay Layers
| 类型 | 耐磨性 | 抗冲击性 | 主要应用 |
|---|---|---|---|
| 碳化铬 | 很高 | 中等的 | 矿业, 水泥, 煤炭处理 |
| Complex carbide | 高的 | 高的 | 混合磨损条件 |
| 碳化钨 | 极高 | 低到中 | 滑动磨损严重 |
| Nickel-based | 中等的 | 高的 | 高温 & 腐蚀 |
| Manganese-based | 中等的 | 很高 | Impact-dominated wear |
3. Why Different Hardfacing Layers Are Needed
- Different wear mechanisms: 磨损, 影响, 侵蚀, 腐蚀
- Different working environments: dry, wet, high temperature, 腐蚀性
- Different service life requirements: short-term vs long-term protection
There is no single hardfacing layer that fits all conditions; selection must match the actual application.
4. Layer Structure of Hardfaced Plate
| 层 | 功能 |
|---|---|
| 堆焊层 | Provides wear resistance |
| Transition layer (if applicable) | 提高粘合强度 |
| 基础钢板 | Provides structural support |
5. Selection Guidelines for Hardfacing Layers
| 健康）状况 | Recommended Layer Type |
|---|---|
| 高耐磨 (煤炭, 水泥, 矿石) | 碳化铬堆焊层 |
| 影响参差不齐 + 磨损 | Complex carbide overlay |
| 极端滑动磨损 | 碳化钨堆焊层 |
| High temperature corrosion | Nickel-based overlay |
| Strong impact loading | Manganese-based overlay |
