クラッドウェアプレート
Clad Wear Plate is a versatile composite material that uses different wear-resistant cladding systems such as chromium carbide, 炭化タングステン, martensitic steel, ceramic composites, and nickel-based alloys. Each material offers different balances of wear resistance, 耐衝撃性, and environmental suitability, allowing engineers to select the most appropriate solution for specific industrial conditions.
- 説明
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, セメント, 発電, 鉄鋼工場, およびバルクマテリアルハンドリングシステム.
The performance of clad wear plates depends mainly on the type of wear-resistant cladding material used on the surface layer.
クラッドウェアプレートの構造
A typical clad wear plate consists of two layers:
- ベースレイヤー: Carbon steel or low-alloy steel for strength and toughness
- クラッド層: Wear-resistant alloy layer for abrasion and erosion resistance
2 つの層は冶金的に結合されています, 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, インパクト, 温度, and particle size.
1. 炭化クロムオーバーレイ (CCO)
This is the most widely used cladding material for wear plates.
- High chromium and carbon content
- Forms hard carbide phases (Cr₇C₃, Cr₂₃C₆)
- 硬度: typically 55–65 HRC
- Excellent resistance to sliding abrasion and particle erosion
Typical applications: mining liners, cement chutes, coal handling systems
2. Tungsten Carbide Composite Layer
A high-end wear-resistant cladding material.
- Contains tungsten carbide (トイレ) particles
- 非常に高い硬度
- Superior abrasion resistance compared to chromium carbide
- Higher cost and specialized use
Typical applications: extreme wear zones, high-value equipment protection
3. Martensitic Steel Overlay
A tough and wear-resistant cladding system based on alloy steel.
- マルテンサイト組織
- バランスの取れた硬度と靱性
- 優れた耐衝撃性
- 適度な耐摩耗性
Typical applications: 重い衝撃 + 着用環境
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
Typical applications: 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
Typical applications: chemical industry, high-temperature equipment
