In this paper, the mechanical and tribological characteristics of TiB2 ceramic coating with and without cobalt (Co) addition developed using tungsten inert gas (TIG) cladding process on AISI 304 stainless steel (SS) were investigated. The effect of TIG process conditions as well as cobalt (Co) content on the microstructure, microhardness and resistance to wear were investigated systematically. The phase identification, microstructure, and elemental distribution map of the clad layer formed on the surface of an AISI 304SS substrate were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS), respectively. Vickers microhardness testing apparatus and a pin-on-disc tribometer were used to evaluate the microhardness, resistance to wear, and coefficient of friction (COF), respectively. The result demonstrates that a dense and defect-free composite coating with a strong metallurgical bond to the substrate is possible. The average microhardness of the TiB2 ceramic coating without Co addition was 1704 HV, and the average wear rate was 15.1576×10-9 g/N-m. In contrast, the TiB2 ceramic coating with Co addition exhibited an improved average microhardness of 1860 HV and a reduced average wear rate of 22.7364×10-9 g/N-m, while the AISI 304SS substrate had an average microhardness of 216 HV and an average wear rate of 200.45×10-9 g/N-m. The conclusion is that the TiB2 ceramic coating with Co addition exhibited superior mechanical and tribological characteristics, demonstrating its suitability for use in wear-resistant components. The higher microhardness of the TiB2 ceramic with Co-added coating indicates enhanced hardness and potential resistance to deformation, while the lower wear rate suggests improved durability and the ability to withstand frictional forces. Therefore, the TiB2 ceramic coating with Co addition shows promise for applications where wear resistance is crucial.

“…It recommends that the higher hardness required at the surface for the applications, lower TIG current must be utilized for deposition of TiB 2 -TiO 2 clad layer on AISI 1020 mild steel. Figure 12 shows the maximum microhardness values achieved by different researchers [27,45,46,47,48,49] by depositing different coating materials on AISI 1020 using tungsten inert gas cladding.…”

“…Therefore TIG cladding process is more suitable for deposition of thick clad layer on substrate due to its low cost and easy to operate [26]. TIG cladding process also provides excellent coating quality and metallurgical bond between the coating layer and substrate surface [27]. Several reports have been demonstrated that the composite coating is successfully deposited on ferrous and non-ferrous substrates by TIG cladding process.…”

The main objective of the present work was to enhance the mechanical properties of AISI 1020 steel by depositing the TiB2-TiO2 composite coating on it with the help of the tungsten inert gas (TIG) cladding process. The semi-solid mixture of 50 wt.% of TiB2 and 50 wt.% of TiO2 was preplaced on AISI 1020 steel and a TIG torch was used as heat source to melt the preplaced layer as well as substrate layer to produce the new coating layer. Characteristics of the cladded layer were examined using Vickers microhardness tester, energy dispersive spectroscopy (EDS), scanning electron microscope (SEM) and X-ray diffractometer (XRD). The TIG currents have shown a significant influence on the microstructure and mechanical properties of the coated layer. Metallography result also shows that the input current of the TIG cladding has considerable effect on the microstructure and quality of the coating. Microstructural changes in the clad layer were studied in detail. The Vickers micro-hardness value of the coated layer increases with decrease in input current and maximum microhardness was achieved about 568 HV0.05 which was about 3.5 times higher than that of the substrate (157 HV0.05). The dry sliding abrasive wear test was performed against EN31 hardened alloy steel as counter body by pin-on-disc tribometer with sliding distance of 1036 meters. The coating produced at lower TIG current (110 A) exhibits minimum average wear rate 1.46 × 10-6 g/Nm while coating processed at higher TIG current (155 A) exhibits higher average wear rate 2.18 × 10-6 g/Nm. It was also concluded that the wear rate of the TiB2-TiO2 coating decreases with decreasing processing current and minimum wear rate (1.46 × 10-6 g/Nm) obtained up to 2.5 times lower as compare to wear of AISI 1020 mild steel substrate (3.65 × 10-6 g/Nm) which makes the TiB2-TiO2 coating suitable for application as wear resistance components. The average coefficient of friction also decreases with increasing TIG current and found maximum (0.76) and minimum (0.58) for the coating deposited at 110 A and 155 A current, respectively.

“…Therefore, GTA cladding has been used to fabricate a thick and hard layer on the surface, and to improve surface properties. It is more economical than the other advanced techniques due to some exclusive characteristics such as easy availability, low cost, low investment, and low maintenance cost [12,13]. There has been a great deal of research and development towards improving the microhardness or wear performance of 304 stainless steel.…”

In this study, Titanium (Ti)-Titanium diboride (TiB2) metal matrix composite (MMC) cladding layers were fabricated on an AISI 304 stainless steel substrate by the gas tungsten arc (GTA) cladding process. The composite cladding layer was produced using different powder mixtures: 85wt.% TiB2-15wt.% Ti, 75wt.% TiB2-25wt.% Ti, and 65wt.% TiB2 -35wt.% Ti. During cladding, the GTA process currents were used in the range of 70A to 90 A with 10A interval differences and the scan speed in the range of 1.1 mm/sec to 1.9 mm/sec with 0.4 mm/sec interval differences. All samples were investigated for mechanical properties, microstructure, and phase analysis by Vickers microhardness, scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD) respectively. The X-ray diffraction (XRD) findings indicate that the composite coatings consist of TiB2, TiB, Ti, Fe3C, B4C, and NiTi phases. The presence of elements B, C, Ti, Cr, Mn, Fe, and Ni in the coating was confirmed by X-ray energy dispersive spectroscopy (EDX). The maximum microhardness value of the composite coating was enhanced in the range of 1639 HV0.1 to 3781 HV0.1, whereas the microhardness of the AISI 304 stainless steel substrate was 194 HV0.1. The average wear rate of the coated samples was determined in the range of 11.09×10-9 g/N-m to 27.63×10-9 g/N-m, whereas the average wear rate of the AISI 304 steel substrate was 88.414×10-9 g/N-m. It can be concluded that the maximum micro-hardness of the composite coating increased by 9-19 times than that of the nominal substrate (AISI 304 stainless steel). Also, the wear resistance of the composite coating enhanced by 8 times as compared to AISI 304 steel substrate. It is demonstrated in this study that the processing current, TiB2 content, and scanning speed have significant effect on the microstructure, mechanical, and tribological features of the cladding layers .
