Abstract
Abstract In this study, NiTi and NiTi-XSiC (1 wt%, 2 wt%, and 4 wt%) powders were coated on the Ti6Al4V surface by the self-propagating high-temperature synthesis (SHS) method using induction heating. Optic microscope and a scanning electron microscope (SEM) for the microstructural properties of coatings, energy dispersive spectrometry (EDS) for element distribution analysis, and X-ray diffractogram (XRD) for phase component analysis were carried out. The microhardness difference between the coating and the substrate was assessed by using the Vickers hardness scale. The microhardness increased with the addition of SiC, and the highest hardness value was 1416 Hv and detected in the sample NiTi–SiC 4 wt%. Phases formed by diffusion during solidification in the compounds Ti, Al, NiTi, NiTi2, NiAl, Ni3Al, Al3Ti, and TiO2, respectively.
