复合耐磨板
Clad Wear Plate is a versatile composite material that uses different wear-resistant cladding systems such as chromium carbide, 碳化钨, martensitic steel, ceramic composites, and nickel-based alloys. Each material offers different balances of wear resistance, 抗冲击性, and environmental suitability, allowing engineers to select the most appropriate solution for specific industrial conditions.
- 描述
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, 水泥, 发电, 钢铁厂, 和散装物料处理系统.
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:
- 基层: Carbon steel or low-alloy steel for strength and toughness
- 熔覆层: Wear-resistant alloy layer for abrasion and erosion resistance
两层冶金结合, 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, 影响, 温度, and particle size.
1. 碳化铬堆焊层 (中科协)
This is the most widely used cladding material for wear plates.
- High chromium and carbon content
- Forms hard carbide phases (Cr₇C₃, Cr2₃C₆)
- 硬度: 通常为 55–65 HRC
- Excellent resistance to sliding abrasion and particle erosion
典型应用: mining liners, 水泥溜槽, coal handling systems
2. Tungsten Carbide Composite Layer
A high-end wear-resistant cladding material.
- Contains tungsten carbide (厕所) 颗粒
- 极高的硬度
- Superior abrasion resistance compared to chromium carbide
- Higher cost and specialized use
典型应用: extreme wear zones, high-value equipment protection
3. Martensitic Steel Overlay
A tough and wear-resistant cladding system based on alloy steel.
- 马氏体显微组织
- 平衡的硬度和韧性
- Good impact resistance
- 中等耐磨性
典型应用: 重大影响 + 磨损环境
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
典型应用: high-speed particle flow systems, pneumatic conveying
5. Nickel-Based Alloy Cladding
Used in special environments requiring corrosion and wear resistance.
- 优异的耐腐蚀性
- Good performance at high temperatures
- Moderate wear resistance compared to carbide systems
典型应用: 化工, high-temperature equipment
