크롬 카바이드 오버레이 마모 플레이트
Chromium Carbide Overlay Wear Plate achieves outstanding wear resistance through a hardfacing layer rich in chromium carbides. This structure provides a strong combination of surface hardness and structural toughness, making it highly effective in extreme abrasion environments.
- 설명
크롬 카바이드 오버레이 마모 플레이트 is a high-performance wear-resistant material produced by depositing a chromium carbide-rich hardfacing layer onto a steel base plate. It is widely used in severe abrasion environments where standard steel materials cannot provide sufficient service life.
Its main advantage comes from the extremely hard carbide structure formed during the overlay welding process.
Hardfacing Structure and Composition
The wear-resistant layer is created through a welding deposition process. The typical structure includes:
- 베이스 플레이트: Mild steel or low-alloy steel for strength and support
- 오버레이 레이어: High-chromium alloy weld deposit
- Hard phase: 크롬 탄화물 (Cr₇C₃ and related carbides)
This structure combines toughness from the base plate and extreme hardness from the carbide layer.
내마모 메커니즘
The excellent wear resistance of Chromium Carbide Overlay Wear Plate comes from its microstructure.
1. High Hardness Carbide Phase
The chromium carbide particles are extremely hard, typically reaching high hardness levels. These particles resist cutting, 긁는 것, and abrasion from hard materials.
2. Two-Layer Protection System
- The hard overlay layer resists direct abrasion
- The steel base absorbs impact and structural stress
This combination prevents cracking and improves service life.
3. Self-Sacrificial Wear Layer
작동 중, only the overlay layer wears gradually while the base plate remains intact, maintaining structural integrity for a long time.
