“…The results obtained by Mridha and Baker [27] and Mridha et al [28] employing TIG processing to modify the melt zone microstructure and microhardness of microalloyed steel through the incorporation of TiC particulates were in agreement with other work [24,25,29]. The microhardness of the BM steel was ~200 Hv.…”

This paper is an invited review of the work undertaken by the present authors and their colleagues listed in the references, using surface engineering to enhance the surface properties of low alloy and microalloyed steels through the addition of ceramic powders.The background to the present projects emanated from work on particulate metal matrix composities (MMC's), which in the 1960's, grew from the development of cermets, at that time a new generation of composite materials designed to have optimal properties, including high temperature resistance and the hardness of a ceramic combined with the ability to undergo plastic deformation like a metal. Generally, the metallic elements used as a binder were nickel, molybdenum, and cobalt, and while cermets, comprised by volume < 20% metal, MMC's normally have ≥80% of metal. Both can be manufactured by a sintering process [1,2]. A more recent version of cermets are MAX phases, some comprising ternary carbides and nitrides of aluminium or titanium alloys [3,4].

“…Many works have shown that greater melting depth from extensive reinforcement dissolution with substrate were achieved by gradual increase of energy inputs using lasers or TIG [1][2][3][4][5]. Others have reported that melt pool size expansions coupled with high dissolution are achieved by manipulating types of used shielding gasses to aid the expansion of melt pool under the TIG works [5,6].…”

“…Others have reported that melt pool size expansions coupled with high dissolution are achieved by manipulating types of used shielding gasses to aid the expansion of melt pool under the TIG works [5,6]. Used of fluxes served the same purpose for diluting the molten metal [2]. Increasing heat inputs, using special shielding gasses, or even adding fluxes to expand the melt volume may incur some amount of additional cost or complexity processing setup and techniques for experimental works.…”

Surface hardening with and without hard reinforcing material can be achieved by melting technique on the top substrate area via high energy input fusion. The aim is to apply TIG torch heat input of 1344 J/mm at two different working distances such as 0.5 mm and 1.5 mm to incorporate the preplaced TiC particulates on the surface of AISI 4340 low alloy steel. Results pertaining to the microstructural features, melt pool sizes, defects, topographies and microhardness were investigated using the optical microscope, scanning electron microscope and Vickers microhardness tester. The results showed that the heat loss through the arc column at 1.5 mm of working distance resulted small melt pool geometry and poor dissolution of TiC particulates. Lower working distance increases heating value leading more precipitation of TiC whilst minimizing those the undissolved particulates. The surface submerged at working distance of 0.5 mm produced microhardness ranging from 800 HV to 1500 HV. The work suggested that heat fusion can be enhanced by marginal working distance whilst saving the energy to melt instead of increasing the used voltage, current, decreasing scanning speed, or adding fluxes or shielding with special gasses.
