Биметаллическая износостойкая пластина: Is It the Same as a Weld Overlay (Hardfaced) Тарелка?
Bimetallic wear plate is a composite wear-resistant steel plate made by combining two different metals into one structure. It typically consists of a carbon steel or low-alloy steel base plate and a high-hardness wear-resistant surface layer.
In industrial practice, bimetallic wear plate is often closely related to наплавка (hardfaced) тарелка, but they are not always exactly the same in manufacturing methods.
1. What Is a Bimetallic Wear Plate?
| Структура | Описание |
|---|---|
| Wear-resistant surface layer | High hardness alloy (например, карбид хрома) |
| Base steel layer | Tough structural steel for strength support |
The key idea is combining твердость + прочность in one material.
2. What Is a Weld Overlay (Hardfaced) Тарелка?
A weld overlay plate is a type of bimetallic wear plate produced specifically by welding deposition (hardfacing process).
- Wear-resistant layer is deposited by welding
- Strong metallurgical bonding is formed
- Most common industrial production method
3. Are They the Same?
| Аспект | Биметаллическая износостойкая пластина | Наложение сварного шва (Hardfaced) Тарелка |
|---|---|---|
| Определение | General term for two-metal structure | Specific type using welding overlay process |
| Manufacturing method | May include welding, прокатка, or bonding | Always welding-based overlay |
| Industrial usage | Broad concept | Most widely used form |
So, all weld overlay plates are bimetallic wear plates, but not all bimetallic wear plates are weld overlay plates.
4. Why Weld Overlay Plates Are the Most Common Type
- Прочная металлургическая связь между слоями.
- High and stable surface hardness (HRC 58–65)
- Flexible alloy design (Кр, Нб, Мо, WC systems)
- Cost-effective for large industrial applications
5. Performance Advantages of Bimetallic Structure
| Слой | Функция |
|---|---|
| Hard surface layer | Resists abrasion and erosion |
| Ductile base layer | Absorbs impact and supports load |
This combination provides both wear resistance and structural toughness.
6. Application Fields
| Промышленность | Типовое оборудование |
|---|---|
| Горное дело | водопад, дробилки, лайнеры |
| Цемент | Бункеры, каналы, циклоны |
| Металлургические заводы | Агломерационные системы, конвейеры |
| Электростанции | Системы обработки угля и золы |

Заключение
Bimetallic wear plate is a general term for two-layer composite steel, while weld overlay (hardfaced) plate is a specific type made by welding deposition. На практике, they are closely related, and weld overlay plates are the most widely used form of bimetallic wear-resistant materials.
