Aluminum pistons are critical components in engines, operating under high temperatures, continuous friction, and cyclic mechanical loads. Over time, pistons may suffer from surface wear, deep scratches, crown damage, or dimensional deviation, leading to reduced performance and increased maintenance costs.
Laser Cladding – A Precision Refurbishment Solution for Aluminum Pistons
Laser Cladding is an advanced surface engineering technology that uses a high-energy laser beam to deposit aluminum alloy powder onto worn or damaged areas of the piston.
The process is precisely controlled, creating a strong metallurgical bond between the deposited layer and the base material, making it especially suitable for surfaces requiring high dimensional accuracy.
Key Advantages
- Minimal heat-affected zone, reducing component distortion
- High-precision deposition, allowing accurate control of coating thickness
- Strong metallurgical bonding with excellent adhesion
- Material compatibility, using aluminum alloy powders matched to the piston
- Extended service life, reducing replacement and maintenance costs

Post-Processing After Refurbishment
After Laser Cladding, the piston undergoes precision machining and finishing to restore dimensional accuracy, roundness, and surface smoothness, ensuring stable and reliable operational performance.
