“…It makes the coatings more prone to delamination during the operation due to poor adhesion with the substrate and drastically affects the service life of the components. 73,74 In an experimental study, Vengudusamy and his team 75 investigated the effect of sp 3 concentration on the tribological performance of self-mated ta-C coating in combination with API group III (A-III) base oil. Two different coatings with sp 3 concentration of 40 and 75% were tested at a temperature of 100°C using identical tribotest conditions.…”

Tribological performance of industrial applications involving boundary lubrication regime can be improved by depositing surface coatings such as diamond-like carbon (DLC) on the interacting surfaces. DLCs are considered as hard coatings with unique combination of properties which results in minimizing the friction induced energy and material losses especially under starved lubrication conditions. In spite of high wear-resistance and ultralow friction coefficients, there are a lot of factors that can directly influence the tribological characteristics of DLC coatings. Although, many studies were conducted to comprehend the effects of intrinsic/extrinsic conditions on tribological behavior of these coatings, still there is a lack of understanding due to contradictory remarks. Therefore, there is a need to rearrange the published data in an organized manner for logical continuation of research. In this paper, a brief introduction of DLC coatings is presented followed by detailed discussion on conditions that can directly influence their tribological properties.

“…When the stress exceeds the interfacial adhesion strength, delamination of the DLC coatings can occur, which eventually impairs the overall performance. In particular, the stress in ta-C is generally around 10 GPa [ 26 ] and delamination easily occurs. Lowering the residual stress by incorporating appropriate elements, such as Si and Ti, in the coatings and depositing interlayers onto the substrates prior to the DLC coatings are widely used methods to avoid delamination.…”

Surface modifi cation is an effective way of improving the tribological properties of base materials and is now actively being used in the automotive industry. Surface wettability can affect the overall performance of automotive components, such as windshields and mirrors, and controlling the surface hydrophobicity or hydrophilicity has been a major focus of research work in this industry. Diamond-like carbon (DLC), which is an amorphous carbon compound with outstanding mechanical and tribological properties, has gained considerable attention as a superior functional coating material and has been successfully applied to a range of mechanical automotive components, leading to better performance and durability. Recently, DLC-based materials with special wettability have been successfully used for the development of superhydrophobic and superhydrophilic surfaces, and a variety of industrial as well as biomedical applications have been proposed. Undoubtedly, being able to control the surface wettability using such DLC-based materials with tunable wettability would expand the original capabilities of the materials used in the automotive industry today. In this chapter, after giving a brief introduction to the fundamentals of surface wettability in relation to DLC coatings, we review recent studies on the control of surface wettability using DLC-based materials and then discuss future outlook.

“…However, the majority of the failures were due to the generation of high internal residual stress between the coating and substrate surfaces resulting in coating delamination (1,3,6,(24)(25)(26)(27)(28). Many authors (1,3,6,24,25) have focused on reducing delamination by adding an adhesion layer such as Silicon (Si), Titanium (Ti), Aluminium (Al) and Chromium (Cr). These adhesion layers create a transition between the substrate and the coating which reduces the likelywood of delamination (1,3,6,24,25).…”

The application of Diamond-like-carbon coatings (DLC) to bearing surfaces is widespread from machining to bio-implants and has resulted in significant study of coating properties. The aim of this investigation was to determine the performance of two diamond-like-carbon coatings, using Chromium and Silicon as adhesion layers. Linear reciprocating wear tests were carried out at room temperature using an AISI 440C steel ball reciprocating against the DLC coated metal substrate. The performance of the coatings under different contact pressures (500 to 3000 MPa); peak sliding velocities (28 to 378 mm/s); and stroke length, (1.5 to 4 mm). An electric resistance measurement was used to monitor coating failure owing to the dielectric nature of the tested coatings.An increase in contact pressure resulted in a decrease in number of cycles to failure for both the coatings. However, the number of cycles to failure increased proportionally with sliding speed. In addition, artifacts on the coating and blister formation generated coating debris which acted as a third body during the wear process. The debris caused complete delamination of the coatings initially at the ends of the wear scar. The Silicon adhesion layer coating samples were found to provide a greater resistance to failure due to it being thicker, harder, and more elastic as compared to samples having a Chromium adhesion layer.
