لوحة ارتداء ثنائية المعدن
Bimetallic Wear Plate combines a tough steel base with a high-hardness alloy wear layer, delivering both structural strength and excellent abrasion resistance. With multiple types such as chromium carbide, كربيد التنغستن, ceramic composite, and manganese-based plates, it can be tailored to different industrial wear conditions. This makes it a highly efficient solution for extending equipment life and reducing maintenance costs in demanding industrial environments.
- وصف
Bimetallic Wear Plate is a composite wear-resistant material made by bonding two different metals together, typically a tough carbon steel base plate and a high-hardness wear-resistant overlay layer. This structure combines the strength and impact resistance of steel with the extreme wear resistance of alloyed surface materials.
ويستخدم على نطاق واسع في التعدين, إنتاج الأسمنت, مصانع الصلب, توليد الطاقة, and bulk material handling industries where both abrasion resistance and structural toughness are required.
الهيكل المادي
A bimetallic wear plate consists of two key layers:
- الطبقة الأساسية: Carbon steel or low-alloy steel for structural strength and impact resistance
- Wear Layer: High-hardness alloy overlay for abrasion and erosion resistance
الطبقتان مرتبطتان معدنيًا, ensuring strong adhesion and long service life under harsh operating conditions.
التركيب الكيميائي لطبقة التآكل
The surface wear layer varies depending on the overlay type, but commonly includes high-chromium carbide alloys.
| عنصر | المحتوى النموذجي (%) | وظيفة |
|---|---|---|
| الكروم (كر) | 20-35 | Forms hard carbides for wear resistance |
| الكربون (ج) | 3-5 | Combines with chromium to form carbide phases |
| حديد (الحديد) | توازن | مادة المصفوفة |
| المنغنيز (من) | كمية صغيرة | يحسن المتانة |
| السيليكون (و) | كمية صغيرة | يستقر عملية اللحام |
These elements form extremely hard carbide compounds such as Cr₇C₃ and Cr₂₃C₆, which are responsible for high abrasion resistance.
التركيب المعدني الأساسي
| عنصر | محتوى (%) |
| الكربون (ج) | .250.25 |
| المنغنيز (من) | 0.5-1.5 |
| السيليكون (و) | .50.5 |
| حديد (الحديد) | توازن |
The base steel provides ductility and impact resistance, preventing brittle failure of the hard surface layer.
خصائص الأداء
مقاومة التآكل العالية
The hard overlay layer provides excellent resistance to sliding abrasion, particle erosion, and material impact wear.
مقاومة جيدة للتأثير
The base steel absorbs mechanical shock and vibration, making the material suitable for combined wear and impact environments.
Strong Bonding Strength
The metallurgical bonding between layers ensures no delamination under normal working conditions.
عمر خدمة ممتد
Compared with traditional steel plates, bimetallic wear plates significantly extend operational life in harsh industrial environments.
