D. Tech. Chemical, Metallurgical and Materials Engineering. / Aims to produce and improve the tribocorrosion property of Ti6Al4V by means of laser surface cladding with Ni and ZrO2. The results of this study would be useful for the design of high performance components for chemical and oil industry and potential applications in other engineering fields. The aim would be achieved through the following objectives: 1. Synthesize and characterise Ti, Ti-Ni and Ti-Ni-ZrO2 admixed powders. 2. Explore the feasibility of laser surface treatment of Ti6Al4V with Ti, Ti-Ni and Ti-Ni-ZrO2. 3. Investigate possible metallurgical interactions and phenomenon during and after laser surface cladding of the composite. 4. Evaluate the microstructural and mechanical properties of Ti based composites in terms of hardness. 5. Analyze the interaction between wear and corrosion wear as well as tribocorrosion resistance of the alloys and composites after laser surface cladding in 3.5 % NaCl and 1M H2SO4 environments.
