DEPENDENCE OF SURFACE ROUGHNESS OF TUNGSTEN CARBIDE ALLOYS ON LASER ABLATION PARAMETERS

Annotation

The laser ablation method has significant advantages in processing workpieces from hard materials, since it ensures the removal of material without wear of the forming tool and load on the workpiece. A method for processing tungsten carbide using laser ablation of nanosecond pulse duration is described. The results of the analysis of the tungsten carbide surface morphology after exposure to short laser pulses are presented. The roughness of the processed surface is studied using the contact profilometry method. The effect of laser exposure parameters (pulse repetition rate, pulse duration) on the geometric parameters (ablation depth and roughness) of the surface of tungsten carbide workpieces is studied. It is found that with an increase in energy density, pulse duration and an increase in the overlap coefficient of laser pulses, the roughness of the processed surface increases. The tangential laser processing strategy is shown to provide the best surface quality.
