- Powder / Wire / Multi-Wire / Hot-Wire compatible
- Scalable from precision repair to large-area production
What Is Laser Cladding？
Laser cladding (Laser Metal Deposition) is a surface engineering process that uses a high-power laser to create a metallurgically bonded coating on a substrate. Metal powder or wire is melted together with a thin surface layer of the base material, forming a dense, low-dilution alloy layer.
Compared with thermal spraying or hard chrome plating, laser cladding delivers superior bonding strength, lower porosity, and significantly longer service life.
Haute efficacité
Electrical-to-optical efficiency up to 60%, significantly reducing energy compared with fiber lasers.
Uniform Energy Distribution
95% beam uniformity eliminates hotspots, stabilizes the melt pool, and reduces cracks and porosity.
Flexible Beam Geometry
Rectangular, circular, elliptical, or linear beams engineered to match real cladding tracks and part geometry.

Laser Cladding vs Conventional Technologies
Laser Cladding
What it is
Laser Cladding (also called Laser Metal Deposition, LMD) est un surface engineering and additive manufacturing process that creates a new functional layer on a metal surface using a high-power laser.
How it works
A focused laser creates a small, controlled melt pool on the substrate
Métal powder or wire is fed into the melt pool
The coating material and a thin layer of the base material melt together
After solidification, a metallurgical bond is formed between coating and substrate
Typical applications
Wear-, corrosion-, and heat-resistant coatings
Hydraulic cylinders, arbres, bearings, moules
Brake discs, drilling tools, agricultural wear parts
Replacement for hard chrome plating and some thermal spray applications
Thermal Spray
What it is
Thermal Spray is a group of coating technologies (such as flame spray, plasma spray, and HVOF) that deposit material onto a surface by spraying molten or semi-molten particles.
How it works
A heat source (flame, plasma, or electric arc) melts the coating material
Molten particles are accelerated toward the substrate at high speed
Particles flatten and solidify on impact
The coating adheres mainly through mechanical bonding, not metallurgical fusion
Typical applications
Large-area wear or corrosion protection
Structural components with low thermal sensitivity
Maintenance and repair coatings
Situations where high deposition rate is required
Hard Chrome Plating
What it is
Hard Chrome Plating is an electrochemical surface treatment that deposits a thin layer of chromium onto a metal part to improve hardness and wear resistance.
How it works
The workpiece is immersed in a chromium-based electrolyte
An electric current causes chromium ions to deposit on the surface
A thin, hard chromium layer is formed
The bond is non-metallurgical and relatively brittle
Typical applications
Hydraulic rods and cylinders
Shafts, guide columns, mold components
Parts requiring low friction and high surface hardness
Limites
Uses hexavalent chromium (environmental and regulatory concerns)
Limited coating thickness
Risk of cracking or peeling under high load or impact
Summary of Key Differences
| Process | Bonding | Porosité | Thickness Control | Impact environnemental |
|---|---|---|---|---|
| Laser Cladding | Metallurgical | Très faible | Excellent | Eco-friendly |
| Thermal Spray | Mécanique | Medium–High | Limité | Moyen |
| Hard Chrome Plating | Mécanique | Faible | Limité | ❌ Hexavalent Chromium |
