In order to predict the geometry character of laser surface micro-texturing, the finite element analyzing software ANSYS is used to simulate temperature field and crater on the laser ablation. The influence and change regulation of laser intensity, laser pulse number and pulse duration in laser surface texturing are analyzed in detail. The simulation results conclude the best laser intensity in laser-pulse and materials interactions on certain conditions, and the best pulse duration in nanosecond laser micromachining. This research establishes the foundation for laser machining regular non-smooth surface in a rapid and effective way.

Surface Topographies

Laser surface texturing improved tribological property is regarded as an optimistic method. However, many technological parameters have crisscross effects on surface topographies, the complexity of relations between variables devoted to a tough way to express functions accurately. Meanwhile, enough basic tents of theory can be borrowed to interruption for obtained the expectation in the process of micro-texturing on critical surfaces. And thus pumping current and number of laser pulse were chosen and studied for improving the surface topographies realized by Nd3+: YAG laser, assisting a better expectation of reduction of abrasive grains. The single-factor method was exerted in the process of analysis, one international 3D-morphology meter and its accessory codes were adopted before the analysis of constitutive influence from pumping current and pulse times in given duration on characteristic parameters of texturing surface, the results are shown in figures by Abbott curve and characteristic parameters which were compared in the literate.
