Clad Wear Plate is a versatile composite material that uses different wear-resistant cladding systems such as chromium carbide, tungsten karbida, martensitic steel, ceramic composites, and nickel-based alloys. Each material offers different balances of wear resistance, resistensi dampak, and environmental suitability, allowing engineers to select the most appropriate solution for specific industrial conditions.
- Keterangan
Clad Wear Plate is a composite wear-resistant steel product made by bonding a high-performance wear-resistant layer onto a carbon steel or low-alloy steel base plate. It is designed to combine structural strength with excellent surface wear resistance, making it widely used in mining, semen, pembangkit listrik, pabrik baja, dan sistem penanganan material curah.
The performance of clad wear plates depends mainly on the type of wear-resistant cladding material used on the surface layer.
Structure of Clad Wear Plate
A typical clad wear plate consists of two layers:
- Lapisan dasar: Carbon steel or low-alloy steel for strength and toughness
- Lapisan Kelongsong: Wear-resistant alloy layer for abrasion and erosion resistance
Kedua lapisan tersebut terikat secara metalurgi, ensuring strong adhesion and long service life under harsh conditions.
Common Wear Resistant Cladding Materials
Different cladding materials are selected based on working conditions such as abrasion, dampak, suhu, and particle size.
1. Hamparan Kromium Karbida (CCO)
This is the most widely used cladding material for wear plates.
- High chromium and carbon content
- Forms hard carbide phases (Cr₇C₃, Cr₂₃C₆)
- Kekerasan: biasanya 55–65 HRC
- Excellent resistance to sliding abrasion and particle erosion
Aplikasi khas: mining liners, saluran semen, coal handling systems
2. Tungsten Carbide Composite Layer
A high-end wear-resistant cladding material.
- Contains tungsten carbide (toilet) partikel
- Kekerasan yang sangat tinggi
- Superior abrasion resistance compared to chromium carbide
- Higher cost and specialized use
Aplikasi khas: extreme wear zones, high-value equipment protection
3. Martensitic Steel Overlay
A tough and wear-resistant cladding system based on alloy steel.
- Struktur mikro martensit
- Kekerasan dan ketangguhan seimbang
- Resistensi dampak yang baik
- Ketahanan abrasi sedang
Aplikasi khas: dampak yang berat + memakai lingkungan
4. Ceramic-Embedded Cladding
A composite system with ceramic particles distributed in a metal matrix.
- Ceramic particles such as alumina or silicon carbide
- Extremely high resistance to particle erosion
- Lower impact resistance compared to metallic overlays
Aplikasi khas: high-speed particle flow systems, pneumatic conveying
5. Nickel-Based Alloy Cladding
Used in special environments requiring corrosion and wear resistance.
- Excellent corrosion resistance
- Good performance at high temperatures
- Moderate wear resistance compared to carbide systems
Aplikasi khas: chemical industry, high-temperature equipment
Performance Comparison of Cladding Materials
