摘要：

Titanium and its alloys are materials found to exhibit wonderful properties such as its lightweight and, excellent mechanical properties - tensile strength and toughness even at elevated temperatures, extraordinary corrosion resistance behaviour and ability to withstand high temperatures. These unique properties have made Ti6Al4V attractive for a range of industrial applications. Some of the successful applications include medical implants and prosthesis, connecting rods for automotive, aerospace, oil and gas, sports equipment, gas turbine engines and space crafts. However, the high cost and poor wear resistance of Ti6Al4V limits its use for specific applications. This study investigates the wear resistance of the laser deposited Ti6Al4V composite and its enhancement with molybdenum. In this study, the Ti6Al4V/Mo composites were produced, the effect of influencing process parameter was investigated, and the produced Ti6Al4V-Mo composites were further examined through various tests. The results revealed that the Ti6Al4V/Mo composite produced at varying laser powers had improved wear resistant when compared to the Ti6Al4V substrate. A direct correlation between the wear resistance and hardness was also observed.
