Laser surface texturing (LST) is one of the surface modification methods that increase or provide new abilities for the material surface. Textured surfaces could be applied in different industrial areas to reduce wear and friction, promote anti-fouling, improve osseointegration, and other similar uses. However, LST is still in development and for reaching industrial level further optimization is required. In this paper, different metal alloy surfaces were fabricated with several patterns using the same laser parameters on each material and the results were compared. This could lead to possible optimization on the industrial level. Furthermore, research on the wettability properties of material and texture patterns depending on heat treatment in different temperatures was performed, showing complete control for wettability (from hydrophilic to hydrophobic).
激光表面纹理化（LST）是一种表面改性方法，可增强材料表面性能或赋予其新的性能。纹理化表面可应用于不同工业领域，以减少磨损和摩擦、促进防污、改善骨结合及其他类似用途。然而，激光表面纹理化仍在发展中，要达到工业应用水平还需要进一步优化。本文使用相同的激光参数在几种材料上制作了不同图案的金属合金表面，并对结果进行了比较。这可能会在工业层面实现优化。此外，还研究了材料和纹理图案在不同温度下的热处理对润湿性的影响，结果表明可以完全控制润湿性（从亲水性到疏水性）。
