Hartbeschichtete Platte: 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, Verschleißfestigkeit, Schlagfestigkeit, und Lebensdauer.
Different welding overlay systems are selected based on working conditions such as abrasion, Auswirkungen, Temperatur, und Korrosion.
1. Main Types of Hardfacing Layers
| Hardfacing Type | Main Composition | Hauptmerkmale |
|---|---|---|
| Chromkarbid-Überzug | Fe + C + Cr (high chromium carbides) | Hervorragende Abriebfestigkeit, most common type |
| Complex carbide overlay | Cr + Nb + Mo + C | Higher toughness and improved wear resistance balance |
| Wolframcarbid-Überzug | WC + Ni/Fe matrix | Extrem hohe Härte, best for severe abrasion |
| Nickel-based overlay | In + Cr + B + Und | 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
| Typ | Verschleißfestigkeit | Schlagfestigkeit | Hauptanwendung |
|---|---|---|---|
| Chromkarbid | Sehr hoch | Medium | Bergbau, Zement, coal handling |
| Complex carbide | Hoch | Hoch | Gemischte Verschleißbedingungen |
| Wolframcarbid | Extrem hoch | Low to medium | Starker Gleitabrieb |
| Nickel-based | Medium | Hoch | Hohe Temperatur & Korrosion |
| Manganese-based | Medium | Sehr hoch | Impact-dominated wear |
3. Why Different Hardfacing Layers Are Needed
- Different wear mechanisms: Abrieb, Auswirkungen, Erosion, Korrosion
- Different working environments: dry, wet, high temperature, ätzend
- 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
| Schicht | Funktion |
|---|---|
| Aufpanzerungsschicht | Bietet Verschleißfestigkeit |
| Transition layer (if applicable) | Verbessert die Haftfestigkeit |
| Grundplatte aus Stahl | Provides structural support |
5. Selection Guidelines for Hardfacing Layers
| Zustand | Recommended Layer Type |
|---|---|
| Hoher Abrieb (Kohle, Zement, Erz) | Chromkarbid-Überzug |
| Gemischte Wirkung + Abrieb | Complex carbide overlay |
| Extremer Gleitverschleiß | Wolframcarbid-Überzug |
| High temperature corrosion | Nickel-based overlay |
| Strong impact loading | Manganese-based overlay |
