Owing to their disordered or amorphous structure, bulk metallic glasses (BMG) possess some unique characteristics like high magnetic permeability, electrical resistivity, hardness and tensile strength, resistance to gamma radiation damage and corrosion. A combination of these properties in BMG makes them attractive for various technological applications. Their high hardness coupled with high strength and corrosion resistance indicates their potential in tribological applications. The magnetic, electrical, mechanical and tribological properties of several BMG such as Fe-, Cu, Zr-based BMG have been studied extensively but only a few studies have been undertaken concerning the tribological properties of Ti-based BMG. Therefore, the purpose of this work is to explore the wear properties of Ti50Cu28Ni15Sn7 bulk metallic glass and its composites by using block-on-roller measurement and compared with SKH 9 high speed steel. The effects of hardness on the overall wear behavior at various loads and scratch distances are investigated. After test, the weight loss of the specimens was measured and the worn surfaces were further characterized by X-ray diffraction, energy dispersive X-ray diffraction, and high-resolution scanning electron microscopy. The whole program will be carried out in two years after careful consideration of experimental works. The main goal in the first year is to evaluate the wear behavior of Ti50Cu28Ni15Sn7 bulk metallic glass. The experimental work in the second year will be similar to that of first year except the materials investigated are Ti50Cu28Ni15Sn7 bulk metallic glass composites. It is expected that the wear mechanism of Ti50Cu28Ni15Sn7 bulk metallic glass and its composites can be fully understand after comprehensive evaluation of all the experimental results obtained in this work.
