Abstract

In this study, the synthesis of the Ti2SC nano layer was investigated by ball milling of Ti, FeS2, and C powders. Formation of MAX phase powder after ball milling and after spark plasma sintered (SPSed) sample was characterized by X-ray diffraction (XRD). The morphology and the microstructure of powders were investigated by scanning electron microscopy (SEM) along with energy-dispersive spectroscopy (EDS). The results of the X-ray diffraction patterns showed the reaction between raw materials and the formation of Ti2SC and TiC phases as well as α-Fe, after 10 h ball milling. Iron in the product was removed by an acid washing with 0.5M HCl. Spark plasma sintering at 1450 °C was used to prepare a bulk Ti2SC sample. Archimedes' test results showed that the sample was consolidated to 98% of the theoretical density. To evaluate the wear behavior of the bulk sample, a pin-on-disk wear device was used. The results of the wear test showed a low wear rate. This low wear rate was attributed to the self-lubricating nature of the Ti2SC nano layer. The friction coefficient for the three forces was also uniform. As the wearing force increased, the wear rate also increased.
