“…cladding and powder made of Ti, BN, and Ni to prepare a TiN-reinforced nickel matrix composite on the surface of 16Mn steel [21]; other researchers have used the power metallurgy method to prepare a nanoscale Cu-based composite with TiN particles [22] In addition, Ti2Cu particles regarded as an inevitable reaction of copper and titanium are a hard and brittle phase and usually used as reinforced particles in copper matrix materials. However, TiN•Ti2Cu-TiN-reinforced copper matrix composites prepared in situ on the surface of a copper device using arc cladding has seldom been reported.…”

“…Among the various surface modification methods, one method-the in situ generation of particle-reinforced composites on the surface of metal materials-has the advantage of high controllability and cost-effectiveness, making it an effective way to enhance the surface wear resistance and service life of equipment [5]. Nowadays, there are several methods of in situ generation on metal surfaces, including arc cladding [6,7], laser cladding [8][9][10][11], electron beam cladding [12,13], and plasma arc cladding [14,15]. Among these methods, arc cladding is becoming one of most promising methods as it is easy to facilitate, highly flexible, and cost-effective.…”

A TiN and TiN·Ti 2 Cu reinforced copper matrix composite layer was cladded onto a T3 copper substrate to improve the anti-wear performance of copper products by means of the nitrogen-shielded gas tungsten arc cladding method (N 2 -GTAC). Better than the traditional preparation method of TiN, the TiN particles in the cladding layer were in situ generated using N atoms of shielding gas and Ti atoms of pre-deposited metal powders. In addition, the composite phase TiN·Ti 2 Cu occurred in the cladding layer, which also had a positive effect on anti-wearing. As Ti increased, the amount and grain size of TiN·Ti 2 Cu and TiN increased as a result. The hardness of the cladding layer increased with the increasing amount of reinforced phase generated in the layer. The hardness of the layer reached a maximum of 410 HV, which is nearly 5.1 times greater than that of copper. The TiN·Ti 2 Cu-and TiN-reinforced phases improved the wear resistance of the cladding layers. The cladding layer with 15 wt % Ti had the longsest launch stage (600 s) and the lowest fiction coefficient (0.56).

“…When compared to conventional approaches, TIG cladding offers several benefits, including high productivity and economical, ease to operate and widespread use, and the elimination of the need for specialized equipment for the production of ceramic reinforced composites. So, TIG cladding has the potential to be employed as a surface reinforcing method [10]. For example, TIG process has also been utilised to developed hard ceramic-based MMC coatings on a different type of steel grades [11,12], and aluminium alloys [13].…”

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.

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.
