Pelat Keausan Bimetal
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, tungsten karbida, 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.
- Keterangan
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.
Ini banyak digunakan di pertambangan, produksi semen, pabrik baja, pembangkit listrik, and bulk material handling industries where both abrasion resistance and structural toughness are required.
Struktur Bahan
A bimetallic wear plate consists of two key layers:
- Lapisan dasar: Carbon steel or low-alloy steel for structural strength and impact resistance
- Wear Layer: High-hardness alloy overlay for abrasion and erosion resistance
Kedua lapisan tersebut terikat secara metalurgi, ensuring strong adhesion and long service life under harsh operating conditions.
Komposisi Kimia Lapisan Keausan
The surface wear layer varies depending on the overlay type, but commonly includes high-chromium carbide alloys.
| Elemen | Konten Khas (%) | Fungsi |
|---|---|---|
| Kromium (Kr) | 20–35 | Forms hard carbides for wear resistance |
| Karbon (C) | 3–5 | Combines with chromium to form carbide phases |
| Besi (Fe) | Keseimbangan | Bahan matriks |
| mangan (M N) | Jumlah kecil | Meningkatkan ketangguhan |
| Silikon (Dan) | Jumlah kecil | Menstabilkan proses pengelasan |
These elements form extremely hard carbide compounds such as Cr₇C₃ and Cr₂₃C₆, which are responsible for high abrasion resistance.
Komposisi Logam Dasar
| Elemen | Isi (%) |
| Karbon (C) | ≤0,25 |
| mangan (M N) | 0.5–1.5 |
| Silikon (Dan) | ≤0,5 |
| Besi (Fe) | Keseimbangan |
The base steel provides ductility and impact resistance, preventing brittle failure of the hard surface layer.
Karakteristik Kinerja
Ketahanan Aus yang Tinggi
The hard overlay layer provides excellent resistance to sliding abrasion, particle erosion, and material impact wear.
Ketahanan Terhadap Dampak Yang Baik
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.
