Tấm mài mòn lưỡng kim: Is It the Same as a Weld Overlay (Hardfaced) Đĩa?
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 lớp phủ mối hàn (hardfaced) đĩa, but they are not always exactly the same in manufacturing methods.
1. What Is a Bimetallic Wear Plate?
| Kết cấu | Sự miêu tả |
|---|---|
| Wear-resistant surface layer | High hardness alloy (ví dụ., crom cacbua) |
| Lớp thép nền | Tough structural steel for strength support |
The key idea is combining độ cứng + sự dẻo dai in one material.
2. What Is a Weld Overlay (Hardfaced) Đĩa?
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?
| Diện mạo | Tấm mài mòn lưỡng kim | Lớp phủ hàn (Hardfaced) Đĩa |
|---|---|---|
| Sự định nghĩa | General term for two-metal structure | Specific type using welding overlay process |
| Manufacturing method | May include welding, lăn, 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
- Liên kết luyện kim mạnh mẽ giữa các lớp
- High and stable surface hardness (HRC 58–65)
- Flexible alloy design (Cr, Nb, Mo, WC systems)
- Cost-effective for large industrial applications
5. Performance Advantages of Bimetallic Structure
| Lớp | Chức năng |
|---|---|
| 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
| Ngành công nghiệp | Typical Equipment |
|---|---|
| Khai thác mỏ | Thác, máy nghiền, lớp lót |
| Xi măng | Phễu, ducts, lốc xoáy |
| Steel plants | Sinter systems, băng tải |
| Nhà máy điện | Hệ thống xử lý than và tro |

Phần kết luận
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. Trong thực tế, they are closely related, and weld overlay plates are the most widely used form of bimetallic wear-resistant materials.
