硬化処理プレート: 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, 耐摩耗性, 耐衝撃性, and service life.
Different welding overlay systems are selected based on working conditions such as abrasion, インパクト, 温度, と腐食.
1. Main Types of Hardfacing Layers
| Hardfacing Type | Main Composition | 主な特長 |
|---|---|---|
| Chromium carbide overlay | fe + C + Cr (high chromium carbides) | 優れた耐摩耗性, most common type |
| Complex carbide overlay | Cr + 注意 + モー + C | Higher toughness and improved wear resistance balance |
| 炭化タングステンオーバーレイ | トイレ + Ni/Fe matrix | 非常に高い硬度, best for severe abrasion |
| Nickel-based overlay | で + Cr + B + そして | 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
| タイプ | 耐摩耗性 | 耐衝撃性 | Main Application |
|---|---|---|---|
| 炭化クロム | 非常に高い | 中くらい | マイニング, セメント, coal handling |
| Complex carbide | 高い | 高い | Mixed wear conditions |
| 炭化タングステン | 非常に高い | Low to medium | 激しい滑り摩耗 |
| Nickel-based | 中くらい | 高い | High temperature & 腐食 |
| Manganese-based | 中くらい | 非常に高い | Impact-dominated wear |
3. Why Different Hardfacing Layers Are Needed
- Different wear mechanisms: 摩耗, インパクト, 侵食, 腐食
- Different working environments: dry, wet, high temperature, 腐食性の
- 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
| 層 | 関数 |
|---|---|
| ハードフェイスレイヤー | Provides wear resistance |
| Transition layer (if applicable) | 接着強度の向上 |
| Base steel plate | Provides structural support |
5. Selection Guidelines for Hardfacing Layers
| 状態 | Recommended Layer Type |
|---|---|
| 高い摩耗性 (石炭, セメント, 鉱石) | Chromium carbide overlay |
| Mixed impact + 摩耗 | Complex carbide overlay |
| Extreme sliding wear | 炭化タングステンオーバーレイ |
| High temperature corrosion | Nickel-based overlay |
| Strong impact loading | Manganese-based overlay |
