Giới thiệu

Phủ lớp bằng laser is an advanced surface-enhancement technology that melts and fuses metal powder onto a substrate, forming a wear-resistant, corrosion-resistant, and high-hardness alloy layer. In the marine industry, phủ lớp bằng laser is widely used for critical ship components exposed to seawater, high load, and continuous mechanical stress. This technology dramatically improves durability, reduces maintenance cost, and increases vessel operational reliability.

Compared to traditional thermal spraying or welding, phủ lớp bằng laser offers stronger metallurgical bonding, higher coating density, superior precision, and longer service life—making it the preferred surface-repair method for modern maritime engineering.

Key Marine Components Using Laser Cladding

Ship Propellers

Phủ lớp bằng laser improves the wear resistance and corrosion resistance of marine propellers, extending operational life and maintaining propulsion efficiency in harsh seawater environments.

Hull Plates

Phủ lớp bằng laser enhances the anti-corrosion capability of hull plating, reducing seawater corrosion and extending hull service life.

Propulsion Shafts and Bearings

Propeller shafts and bearings experience continuous torque and vibration. Phủ lớp bằng laser increases fatigue strength, improves wear resistance, and enhances component reliability.

Deck Machinery and Crane Components

Deck equipment operates under constant friction and salt-fog exposure. Phủ lớp bằng laser strengthens surfaces to prevent abrasion and corrosion.

Hydraulic System Components

Hydraulic cylinders, rods, and pistons on ships work under pressure and corrosive environmental conditions. Phủ lớp bằng laser improves corrosion resistance and wear protection to ensure reliable long-term performance.

Common Marine Equipment Problems

Severe Wear

Propellers, shafts, and deck machinery face continuous load cycles and abrasive conditions, leading to rapid wear.

Corrosion Damage

Saltwater exposure accelerates metal corrosion, shortening component life and increasing repair costs.

Fatigue Failures

High-load operation causes micro-cracks and fatigue damage, risking propulsion failure and maritime safety.

Laser Cladding Solutions for Marine Engineering

High-Hardness Wear-Resistant Layers

Phủ lớp bằng laser creates a dense, metallurgically bonded protective surface that significantly reduces wear and deformation.

Corrosion-Resistant Alloy Coatings

Using nickel-based, stainless, and anti-salt corrosion alloys, phủ lớp bằng laser protects components exposed to seawater and salt spray.

Fatigue-Enhanced Protective Coatings

Special alloy powders provide high fatigue strength, ensuring stable performance under long-term cyclic loads.
