Laser surface treatment is a versatile technology offering two distinct approaches for surface preparation, each serving a unique purpose.
The first method is laser cleaning：
This process utilizes laser energy to ablate and remove contaminants like rust, oils, and oxides from a substrate.
The pollutants are vaporized, leaving behind an exceptionally clean and smooth surface.
This is ideal for applications requiring ultra-cleanliness, such as in the aerospace or semiconductor industries, prior to bonding or welding.
Conversely, the second method intentionally uses a laser's high energy and pulsed characteristics to create a controlled, roughened surface.
By selectively removing material, it generates a complex micro-texture with increased surface area.
This engineered roughness is crucial for achieving high-quality thermal spray coatings or paint applications. The enhanced mechanical interlocking significantly improves coating adhesion and durability, preventing delamination under stress.
In summary, while one technique cleans and smoothens, the other strategically roughens; both harness laser precision to optimally prepare surfaces for subsequent industrial processes.
