| Abstract Scope |
In this work in-situ grown titanium carbide/Fe matrix surface composite coating were manufactured by Tungsten inert gas arcing. The results showed that the microstructure of modified surface consist of titanium carbide in martensite matrix via in situ formation. Further the shape and size of the carbide were evaluated using carbon replica method and characterized in Transmission Electron Microscope with STEM imaging mode. The shape of the precipitate consists of cubical structure. Thermodynamic prediction of the fusion zone was evaluated using Thermo-Calc software. Thermal profile of the molten pool suggests that the cooling rate and thermal gradient were fairly high to transform into the martensite phase. Significant increase in hardness and improvement in wear behavior of the modified region was observed with the change in chemical composition and the phase transformation. |
