“…The fatigue resistance of aluminum alloy AA 7075 is less than 5 million cycles, with a maximum stress of 140-160 MPa in high fatigue cycle fatigue [4]. As previously stated, several surface treatment procedures such as induction hardening, nitriding, case hardening, shot peening, roll peening, and laser shock peening, and coating methods such as HVOF, TIG, microwave can greatly improve the fatigue behavior of materials [5][6][7][8][9][10][11][12][13][14][15][16].…”

This study aims to investigate the effects of titanium coatings on aluminum alloy's tribological and fatigue properties. In this investigation, aluminum alloy samples were coated with 1 µm, 3 µm, and 5 µm using the vacuum arc melting method. The morphological and mechanical features of the samples were characterized with SEM, microhardness, contact nanoprofilometer, and calotest methods. The raising of coating thickness by varying the parameters eventually provides strong adhesion properties and enhances the surface hardness of the samples. Further, hard sub-surface layers on the aluminum alloy substrate increased fatigue resistance. The superior mechanical properties, such as microhardness, lower surface roughness, and good bonding at the interface, are critical factors in increasing the fatigue and wear resistance of the aluminum alloy. No traces of defects, such as microcracks and porosity, were found on the coated samples. The microhardness of the coated sample increased by 3.69 times that of the AK5M2 aluminum alloy. The fatigue lifetime of the 5 µm coated samples was increased by 21%. The wear resistance of titanium-coated samples showed better wear resistance against the steel counter body than other coated and uncoated samples.

“…Several researchers improved the wear characteristics of titanium alloy by fabricating layers on the surface of titanium alloy. [28][29][30][31][32] The thickness of the deposit and the amount of heat input have the most significant influence on the properties of the hard-faced components. The heat input on the substrate surface caused the substrate material to partially melt during the deposition of the first layer of hard-facing alloy.…”

“…At the same time, the coating is responsible for resistance to thermal loads, wear, and corrosion. 17,18 Many engineering applications require materials with high resistance to chemical attacks and wear and the ability to perform intended functions in hostile environments and operating circumstances. The effects of adverse environmental and severe operating conditions are primarily limited to surfaces.…”

In this study, the impact of substrate dilution on the microstructure and tribological properties of tungsten inert gas (TIG)-deposited self-lubricating claddings was investigated. The dilution of Ti content on cladding increased as the TIG current increased, and the microhardness of the cladding decreased. The content of intermetallic phases such as TiNi and TiC increased with the increase in TIG current. The tribological studies revealed that coating dilution at higher TIG currents has prominent effects on wear behaviour at elevated temperatures. In both clads, the percentage decrease in hardness from higher TIG current to lower TIG current was noted as 31%. The higher dilution of Ti content in the cladding was found to be beneficial in tribological studies performed, especially at higher temperatures (≥400). Also, solid lubricants such as MoS2 and BaF2 encapsulation in the nickel alloy were found to be beneficial at both low and high temperatures.
