Abstract
In this study, tungsten inert gas (TIG) and microwave hybrid heating (MHH) cladding techniques are used to develop thick nickel-based alloy clad layers of 1mm thickness on a titanium 31 alloy substrate. In TIG cladding consider current was considered as a process variable, whereas in MHH cladding, exposure time was considered as the process variable. Scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) is used to analyze the morphology of both clad layers. The Vickers indentation method is used to determine the hardness values of the clads. The result revealed that the process current in TIG and the exposure time in MHH cladding have a significant effect on the clad layer quality. The average hardness of the TIG clad layer was found to be 1.6 times greater than the MHH processed clad layer. The XRD analysis confirmed the presence of intermetallic phases Ni4W, TiNi, and TiC. The phases TiNi and TiC are responsible for metallurgical bonding in the clad layer.
