| dc.description.abstract | Ti6Al4V alloy is one of the most widely utilized engineering metals, but it has a reduced hardness for high-temperature abrasive applications. In order to modify the surface of a Ti6Al4V alloy plate, a Cobalt-Nickel (Co-Ni) powder combination with increased hardness and corrosion resistance was used during the laser cladding pro cess. For optimal efciency, the Co proportion of the powder was modifed between 30, 50, and 70 wt% respectively. The scan speed and laser power of the operation process were modifed between 0.6, 0.9, and 1.2 m/s and 700, 800, and 900 W respectively. The response properties examined include; microhardness of the coat ing, surface roughness, and clad depth. Response surface methodology was utilized in the experimental design, response property modeling, and process optimization respectively. The statistical analysis revealed that the input variables had signifcant efects on the response properties and that the trend of the responses depended on the interaction pattern between the input variables. The developed numerical mod els were validated for property prediction. It was noted that the optimization pro cedure and confrmation experiments produced response properties with marginal error. The optimal input combination for producing the balanced performance of the Co-Ni coating on the Ti6Al4V alloy substrate yielded 70wt.% Co proportion, 0.86 m/s scan speed, and 900 W laser power respectively. | |
