Laser texturing technology

laser texturing

Laser texturing is an advanced surface engineering technology that uses high-energy density laser beams to micro process the surface of metal materials, forming specific roughness and morphology. The core principle is to use laser instantaneous action to locally melt, vaporize, and plasma the

surface of the material, and then through surface tension and rapid cooling, form small and uniform pits or protrusions.

This technology first focuses the laser beam into an extremely small spot through an optical system, and precisely controls its energy, pulse frequency, and duration of action. Laser scans the surface of the workpiece with high-frequency pulses, instantly heating the affected area above the melting point, melting the material to form a molten pool. After the laser is removed, the molten pool rapidly cools and solidifies, forming micro pits or nodular protrusions. By adjusting laser parameters and spot overlap, the size, depth, and distribution density of pits can be controlled to achieve different surface roughness and friction performance.

The core advantages of laser texturing

Compared to traditional texturing techniques, laser texturing has significant advantages:

Strong texture controllability, which can accurately control the roughness, texture shape, and distribution density of the roughened surface;

High processing accuracy, capable of achieving "local roughening" without damaging the overall performance of the material;

Environmentally friendly, with no dust, acidic or alkaline waste liquid, only producing a small amount of treatable vaporized smoke and dust;

High efficiency, good stability, non-contact processing without tool wear, fast processing speed and high texture consistency;

Wide range of applicable materials, can be used for almost all solid materials.
