Abstract Scope |
The talk will cover the joining process of Titanium (Ti) metal sheet, sandwiched between two pre-sintered Titanium dioxide (TiO2) pellets via novel Flash joining technique. This method employs Direct Current (DC) to enable rapid diffusion due to Joule heating across stacked layers resulting in a reliable and continuous joining of the multi-layered structure. The effect of processing variables on joined interfaces was compared in terms of microstructure. The current directionality had a differential effect on the two interfaces. Complimentarily, hardness at the cathodic interface was found to be higher than that at the anodic interface. Raman and X-ray photoelectron spectroscopy (XPS) supported the proposed hypothesis. The study reveals the directional effect of the current on joining ceramics to metals to attain superior structural integrity for complex multi-layered structures. |
