Abstract
The paper presents the results of investigation of ns-laser pulse interaction with Ni-TiC sample. The present study investigates the effects of the irradiation parameters on the microstructure and surface in-situ composites obtained by the high temperature solution method (HTS). The obtained ingots were irradiated with Nd:YAG laser pulses (Quantel Brio, 4ns, 70mJ@1.06μm), focused with a lens of the focal length of 10 cm in air conditions. Microstructure of the laser irradiated in-situ composites was characterized by the Hirox digital microscope systems which made possible to observe a 3D microscopic images of the composite surface and structural changes after the series of laser irradiation. The study of melted crater ratio has been done on composites to investigate the effect of irradiation on composite surface microstructure. Microstructure of the Ni–TiC composites was also characterized by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). According to experimental results and analysis, it was shown that the observed craters on surfaces were deepened with increasing numbers of laser shot. On the other hand, heterogeneity of samples had influence on the depth of the crater.
