Laser texturing is a process that alters a material’s surface properties by modifying its roughness or, more precisely, its texture. The laser beam creates micropatterns on the surface through laser ablation, removing layers with micrometer precision and perfect repeatability. Typical patterns include dimples, grooves, and free forms.
Laser surface texturing can be used to improve properties like adherence, wettability, electrical and thermal conductivity, and friction. For example, you can increase surface adherence before applying a coating to increase the coating’s lifetime. Laser texturing can also be used to prepare surfaces for thermal spray coating and laser cladding.
A Texturing Process Without Consumables
Surface treatments like abrasive blasting and chemical etching need consumables like steel grits and acid to texture surfaces. Unlike those treatments, the laser texturing process functions without consumables. This results in low operating costs, low maintenance, and improved health and safety in the workplace.
Operators won’t need to handle chemicals, wear protective equipment, and stop operations to replace consumables. Our team will make sure that you have a proper fume extraction system and that your product is class-1 compliant according to international laser safety standards.
How Does Laser Surface Texturing Work?
Laser texturing uses laser ablation to selectively remove materials from specific surface areas. By adjusting the laser’s parameters, we’re able to control how much surface is removed as well as create different patterns. This typically increases roughness, creating surface textures that can easily lodge adhesives and generate more friction.
To reach the material’s ablation threshold, pulsed lasers concentrate energy to reach a high peak power. Typically, the pulse duration is 100 nanoseconds, and each pulse contains between 0.5 and 1 millijoules. The time required to texture a surface depends on the material, the desired roughness level, and the laser system’s output power.
