Notes:
This study is to examine wear properties of Ti-Nb-Si alloys under dry condition and toinvestigate its wear mechanism. A ball-on-disc type wear testing machine was used to evaluate thewear factor. Optical microstructure observation revealed that the microstructure appeared to mixtureappearance consisting of β phase and small amount of α″ martensite phase. Yield strength increasedwith increasing Nb and Si content. Wear resistance of the present alloy are strongly dependent uponyield strength and elastic modulus. Energy dispersive spectroscopy (EDS) and X-ray diffraction(XRD) analysis confirmed the tribo-chemical reaction between the alumina ball and the present alloyoccurs due to decomposition of alumina to aluminum
