How It Works

Laser cleaning is a modern technique that uses high-powered lasers to remove contaminants, coatings, and rust from the surface of various materials. The process works by directing a focused beam of light onto the material's surface, which interacts with the contaminants.

Here’s how it typically works:

1. Absorption of Energy: The laser beam is absorbed by the contaminants or unwanted coatings. The energy from the laser heats these materials rapidly.

2. Thermal Expansion: As the contaminants absorb the laser energy, they expand quickly due to the heat. This sudden expansion causes a rupture or spallation effect.

3. Removal of Contaminants: The force from the thermal expansion dislodges the contaminants from the substrate, effectively cleaning the surface without damaging the underlying material.

4. Control: The process allows for precise control over the cleaning depth and area, making it suitable for delicate surfaces or intricate components.

Laser cleaning is often used in various applications, such as restoring historical artifacts, preparing surfaces for welding or painting, and removing corrosion from machinery. It has several advantages over traditional cleaning methods, including minimal waste, reduced chemical use, and the ability to clean various materials safely.
