| Abstract Scope |
Tungsten inert gas arcing as a surface treatment process with the dilution of the base material can be used for developing surface composite. In this work, in-situ grown vanadium carbide/Fe matrix surface composite coating was manufactured by Tungsten inert gas arcing. The microstructure of the modified surface consists of vanadium carbide in the martensite matrix via in situ formation. Further, the shape and size of the vanadium carbide were evaluated using a carbon replica method and characterized in Transmission Electron Microscope with STEM imaging mode. The shape of the precipitate consists of a cubical structure. Thermodynamic prediction was evaluated using Thermo-Calc software. The thermal profile of the molten pool suggests that the cooling rate and thermal gradient were fairly high. A significant increase in hardness and improvement in wear behavior of the modified region was observed owing to the in situ formation of vanadium carbide in the martensite matrix. |
