Abstract
In order to improve the hardness and microstructural behaviour of AISI 304 austenitic stainless steel, TiC and TiC- steel composite layer was deposited by tungsten inert gas (TIG) cladding/alloying process. Depending upon the heat input into the molten pool and mixing ratio with steel substrate, TiC clad layer or TiC-steel alloyed layer deposited on or within the steel substrate. Clad/alloyed layer height/depth and corresponding microstructure was analyzed by FESEM and EDS. The composition of the clad/alloyed layer was assessed by Xray diffraction (XRD), and hardness was measured by Vickers micro indentation hardness tester. Also effect of TIG welding current and scan velocity on the clad/alloyed layer geometry (depth, width and crater depth) and corresponding microstructure was investigated
