Abstract Scope |
Ti6Al4V is an important alloy with high strength-to-weigh ratio used in aerospace industry. The weight saving that can be provided by this material can further be enhanced if the properties can further be improved for application deserving high hardness and high temperature resistance such as aerospace engine parts. In this paper, we investigate the influence of laser power on the microstructure and microhardness of laser metal deposited tungsten and titanium carbide powders on Ti6Al4V substrate. The scanning speed was maintained at 5 mm/sec while the powder flowrate of tungsten and TiC were maintained at 0.5 rpm. The gas flowrate was kept constant at 2 l/min while the shield gas was maintained at 15 l/min. The laser power was varied between 1000 and 2000 watt. The microstructure of the samples were studied using scanning electron microscope and the microhardness also studied using microhardness indenter. The results are presented and fully discussed. |
