Beschichtete Verschleißplatte

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, Zement, Stromerzeugung, Stahlwerke, und Schüttguthandhabungssysteme.

The performance of clad wear plates depends mainly on the type of wear-resistant cladding material used on the surface layer.

Struktur der plattierten Verschleißplatte

A typical clad wear plate consists of two layers:

• Basisschicht: Carbon steel or low-alloy steel for strength and toughness
• Verkleidungsschicht: Wear-resistant alloy layer for abrasion and erosion resistance

Die beiden Schichten sind metallurgisch verbunden, 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, Auswirkungen, Temperatur, and particle size.

1. Chrom -Carbid -Overlay (CCO)

This is the most widely used cladding material for wear plates.

• High chromium and carbon content
• Forms hard carbide phases (Cr₇C₃, Cr₂₃C₆)
• Härte: typischerweise 55–65 HRC
• Excellent resistance to sliding abrasion and particle erosion

Typische Anwendungen: mining liners, cement chutes, coal handling systems

2. Tungsten Carbide Composite Layer

A high-end wear-resistant cladding material.

• Contains tungsten carbide (WC) Partikel
• Extrem hohe Härte
• Superior abrasion resistance compared to chromium carbide
• Higher cost and specialized use

Typische Anwendungen: extreme wear zones, high-value equipment protection

3. Martensitic Steel Overlay

A tough and wear-resistant cladding system based on alloy steel.

• Martensitische Mikrostruktur
• Ausgewogene Härte und Zähigkeit
• Gute Schlagfestigkeit
• Mäßige Abriebfestigkeit

Typische Anwendungen: schwerer Aufprall + Verschleißumgebungen

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

Typische Anwendungen: high-speed particle flow systems, pneumatic conveying

5. Nickel-Based Alloy Cladding

Used in special environments requiring corrosion and wear resistance.

• Ausgezeichnete Korrosionsbeständigkeit
• Good performance at high temperatures
• Moderate wear resistance compared to carbide systems

Typische Anwendungen: chemical industry, high-temperature equipment
