Abstract

Quality of modified specimens mainly depends on the mechanical properties of the alloying material and the warmth influenced zone (HAZ), which is in direct connection with the kind of welding procedure and its parameters. Dab width and profundity of entrance were by and large impacted by welding process parameters i.e., welding current, travel speed, remain off separation, protecting gas stream rate, tip edge and voltage and further more it assumes a significant job in deciding the surface properties of the changed layer, for example, surface hardness, wear rate and so on. In this investigation, impact of surface properties by fluctuating the procedure parameters has been examined on the AISI 304 tempered steel bars of size 30x30x100 mm surface adjusted with economically unadulterated titanium of thickness 0.3 mm. The surface alloying of AISI 304 hardened steel with Ti were completed by Gas Tungsten Arc (GTA) under N2 climate. Optical microscopy was utilized to discover the microstructure and Energy Dispersive Spectroscopy (EDS) was utilized to discover the level of substance sythesis in the Ti altered layer. The X-Ray Diffraction examination (XRD) was utilized to describe the Ti adjusted layer. The surface hardness and the wear rate of the Ti changed layer were explored by Vickers hardness testing machine and Pin-on-circle wear testing machine. Results showed that perception of the microstructure of the surface alloyed layer uncovers grain refinement. The intermetallic mixes FeTi, TiN and TiNi were shaped utilizing XRD examination. The hardness expanded from 264 HV for the substrate to 2679 HV for Ti adjusted layer. The Coefficient of contact is practically consistent for substrate and surface alloyed example. The EDAX investigation demonstrates an expansion in the Ti content on the altered layer when contrasted and the piece of the substrate. A set of examinations has been led to gather the trial information utilizing focal composite plan of reaction surface philosophy. In light of the recorded information, the ANOVA tables have been created. Further a model approval has been done to affirm the estimation of yield reactions, for example, profundity of infiltration, hardness and wear rate that are equivalent to the ideal worth which are determined utilizing ANOVA table.
