하드페이스드 플레이트: 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, 내마모성, 충격 저항, 및 서비스 수명.
Different welding overlay systems are selected based on working conditions such as abrasion, 영향, 온도, 부식.
1. Main Types of Hardfacing Layers
| Hardfacing Type | Main Composition | 주요 기능 |
|---|---|---|
| 크롬 카바이드 오버레이 | 철 + 기음 + Cr (high chromium carbides) | 우수한 내마모성, most common type |
| Complex carbide overlay | Cr + NB + 모 + 기음 | Higher toughness and improved wear resistance balance |
| 텅스텐 카바이드 오버레이 | 화장실 + Ni/Fe matrix | 매우 높은 경도, best for severe abrasion |
| Nickel-based overlay | ~ 안에 + Cr + 비 + 그리고 | 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
| 유형 | 내마모성 | 충격 저항 | 주요 응용 프로그램 |
|---|---|---|---|
| 크롬탄화물 | 매우 높음 | 중간 | 채광, 시멘트, 석탄 취급 |
| Complex carbide | 높은 | 높은 | 혼합 마모 조건 |
| 텅스텐 카바이드 | 매우 높음 | Low to medium | 심한 슬라이딩 마모 |
| Nickel-based | 중간 | 높은 | 고온 & 부식 |
| Manganese-based | 중간 | 매우 높음 | Impact-dominated wear |
3. Why Different Hardfacing Layers Are Needed
- Different wear mechanisms: 연마, 영향, 부식, 부식
- Different working environments: dry, wet, high temperature, 신랄한
- 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
| 층 | 기능 |
|---|---|
| 표면경화층 | Provides wear resistance |
| Transition layer (if applicable) | 접착력 향상 |
| 베이스 강판 | Provides structural support |
5. Selection Guidelines for Hardfacing Layers
| 상태 | Recommended Layer Type |
|---|---|
| 높은 마모 (석탄, 시멘트, 광석) | 크롬 카바이드 오버레이 |
| 혼합된 영향 + 연마 | Complex carbide overlay |
| 극도의 슬라이딩 마모 | 텅스텐 카바이드 오버레이 |
| High temperature corrosion | Nickel-based overlay |
| Strong impact loading | Manganese-based overlay |
