TiC Coating on AISI 304 Stainless Steel by Tungsten Inert Gas (TIG) Cladding Using Preplaced Powder

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
