لوحة ارتداء تراكب كربيد الكروم: Surface Characteristics of Hardfaced Steel Plate
Chromium carbide overlay wear plate (لوحة CCO) is a composite steel plate produced by depositing a high-chromium carbide alloy layer onto a carbon steel or low-alloy steel base. Its performance is defined primarily by its surface layer characteristics, which directly determine wear resistance and service life.
Compared with ordinary steel plates, the surface of CCO plates has a completely different microstructure and mechanical behavior.
1. Extremely High Surface Hardness
| مادة | صلابة السطح |
|---|---|
| Chromium carbide overlay layer | مجلس حقوق الإنسان 58-65 |
| فولاذ مقاوم للاهتراء (NM400/NM500) | HB 400-500 |
| Ordinary carbon steel | HB 120–200 |
The high hardness comes from large amounts of primary and eutectic chromium carbide particles embedded in the weld matrix.
2. Visible Surface Cracking Pattern (Stress Relief Cracks)
A unique feature of CCO plates is the presence of controlled micro-cracks on the surface.
- These cracks are normal and intentional
- They help release internal welding stress
- They do not affect wear performance
This is a key visual difference from traditional steel plates.
3. Carbide-Rich Microstructure
| عنصر | وظيفة |
|---|---|
| كربيدات الكروم (Cr7C3, Cr23C6) | Main wear-resistant phase |
| Iron-based matrix | Supports carbide structure |
| Alloy additives (ج, من, ملحوظة, شهر) | Improve hardness and stability |
The surface is essentially a “carbide armor layer” designed for extreme abrasion resistance.
4. Excellent Abrasion Resistance Surface
- Strong resistance to sliding abrasion
- High durability against fine particle erosion
- Stable performance in dry wear environments
This makes it ideal for coal, أسمنت, رمل, خام, وأنظمة مناولة المواد السائبة.
5. Smooth but Extremely Hard Surface Texture
Although very hard, the surface is relatively smooth due to controlled welding and finishing processes.
- Reduces material sticking
- Improves flow in chutes and hoppers
- Minimizes frictional resistance
6. Bimetallic Surface-Bond Structure
| طبقة | Surface Function |
|---|---|
| طبقة تراكب | Provides wear resistance |
| Fusion zone | Metallurgical bonding layer |
| الصلب الأساسي | Provides toughness and strength |
The surface layer is firmly bonded to the base plate through metallurgical fusion, not mechanical attachment.
