In this study, laser ablation of bulk NiTi in water was investigated. An alloy bulk of NiTi was synthesized with equal atomic percent of Ni and Ti in vaccum electric arc furnace. NiTi bulk was investigated by XRD experiment. results certificate accuracy of product process. To laser ablation, beam of Q switched Nd:YAG laser(1064nm) focused on NiTi target immersed in water. in result, black colloid solution consists of dispersed particles was obtained. To investigate ablated particles, UV-Vis absorption spectroscopy and XRD were used. results certificate dominant presence of Ni particles in colloid solution. accumulation of nickel particles in air/oxide interface of bulk NiTi is due to thermal effects of nanosecond Q switched Nd:YAG laser.

Keywords: XRD, laser ablation, colloid solution, nanoparticle, NiTi
