“…The unmelted TiC was composed of undissolved TiC particulates in the iron matrix. The presence of unmelted TiC during the coating processes with surface melting was also found in similar works in the literature [25,26]. The highest amounts of titanium and carbon were observed in the unmelted carbide region.…”

Plasma transferred arc (PTA) welding methods were used to produce titanium carbide (TiC) composite coating layers on the surface of 38MnVS6 steel and subsequently deep cryogenic treatment (DCT) was applied to the PTA coating layers. The effects of the TiC powder, different energy inputs (100 and 120A), and DCT on the microstructure and tribological performance were investigated. The microstructure of the composite coatings consisted of cubic TiC, unmelted TiC, and iron matrix. The alloyed and cryogenic treated surfaces exhibited decreases in the coefficient of friction (COF) and wear rate. The average COF of the steel substrate was determined to be 0.373, but for the TiC composite coating layers it varied between 0.236 and 0.33. PTA coating and DCT processes improved the wear resistance 4.5 times compared to the substrate.

“…Because they populated in this region microhardness is high seeing over than 1000 HV up to 600 µm of depth. At 500 µm from the surface, the hardness was 1500 HV which is about twice higher that the overlapped TiC metal matrix composite sample used for the room temperature sliding wear work [14]. Below than 500 µm the hardness gradually declines reaching 1 mm with a similar behaviour reported elsewhere [15].…”

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.

“…The current research considered TiC particulates in the size range of 45–100 µm, melted into the surface of an AISI 4340 low-alloy steel using the TIG technique. At room temperature, it has been shown that the wear resistance of a resolidified zone, incorporating TiC particles, was 21 times greater than that of the unmodified low-alloy steel substrate [22]. This is a relevant justification for further investigation to consider the wear resistance of this system at 600°C.…”

The work aimed to develop surfaces that could resist wear at high temperatures, thus achieving a prolonged component life. Surface modification of a low-alloy steel by incorporating TiC particles has been undertaken by melting the surface using a tungsten inert gas torch. The dry sliding wear behaviour at 600°C of the original and modified surfaces was compared. Microscopic examination of both surfaces showed glazed layers across the wear tracks, with differing amounts of oxide and homogeneity. Extensive wear occurred on the steel surface, which showed deformation of the wear scar tracks and a steadily increased friction coefficient. The TiC addition reduced the wear loss, coinciding with a glazed layer 33% thinner than that on the low-alloy steel sample
