Paper Title:
Dry Sliding Wear Characteristics of Ti-Nb-Si Alloys for Biomedical Application
  Abstract

This study is to examine wear properties of Ti-Nb-Si alloys under dry condition and to investigate its wear mechanism. A ball-on-disc type wear testing machine was used to evaluate the wear factor. Optical microstructure observation revealed that the microstructure appeared to mixture appearance consisting of β phase and small amount of α″ martensite phase. Yield strength increased with increasing Nb and Si content. Wear resistance of the present alloy are strongly dependent upon yield 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 alloy occurs due to decomposition of alumina to aluminum.
