에이 clad wear plate is a composite abrasion-resistant steel plate manufactured by bonding a high-hardness wear-resistant layer onto a carbon steel or low-alloy steel base plate. 광산에서 널리 사용됩니다., 시멘트, 철강 공장, 발전소, and bulk material handling systems where extreme wear and impact conditions exist.

Unlike solid AR steels (such as AR400 or AR500), clad wear plates achieve wear resistance through a surface overlay layer, while the base plate provides strength and toughness.

What Is a Clad Wear Plate?

A clad wear plate typically consists of two main layers:

• 베이스 레이어: carbon steel or structural steel (for strength and support)
• Cladding layer: high-hardness alloy (내마모성을 위해)

The two layers are metallurgically or mechanically bonded to act as a single plate.

Main Manufacturing Processes of Clad Wear Plates

1. Weld Overlay Cladding (하드페이싱)

This is the most common process.

프로세스 원리:

A wear-resistant alloy is deposited onto the steel surface using welding.

Typical Methods:

• 플럭스 코어 아크 용접 (FCAW)
• 서브머지드 아크 용접 (봤다)
• 오픈 아크 용접

Cladding Materials:

• Chromium carbide alloys
• High chromium iron alloys
• Martensitic wear-resistant alloys

주요 기능:

• Strong metallurgical bond
• 매우 높은 내마모성
• Suitable for thick wear layers

2. Explosion Bonding (Explosive Cladding)

A high-energy bonding process using controlled explosive force.

프로세스 원리:

• Two metal layers are accelerated at high speed
• High-pressure impact creates a metallurgical bond

주요 기능:

• Extremely strong bonding strength
• No melting of base material
• Suitable for large plates

제한사항:

• 더 높은 비용
• Limited thickness control

3. Hot Rolling Cladding

A solid-state bonding process performed under high temperature and pressure.

프로세스 원리:

• Base plate and cladding layer are heated
• Rolled together under high pressure

주요 기능:

• Uniform bonding
• Large-scale industrial production
• 좋은 표면 품질

4. 레이저 클래딩 (Advanced Process)

A modern precision coating method.

프로세스 원리:

• Laser melts a small area of base surface
• Powdered alloy is added and fused
• Forms a metallurgically bonded layer

주요 기능:

• 높은 정밀도
• Low dilution rate
• 우수한 내마모성 및 내식성
• Suitable for high-value components

5. 열 스프레이 코팅 (Less Common for Plates)

Process Types:

• HVOF (고속 산소 연료)
• 플라즈마 분사

주요 기능:

• No deep metallurgical bonding
• Thin coating layer
• Lower cost but weaker bond strength

Structure of Clad Wear Plate

This structure allows the plate to handle both abrasion and structural load.
