“…Of particular interest for some applications are diamond nanoparticles, or nanodiamonds (NDs), which offer high thermal conductivity, high hardness, high melting point and the ability to withstand extreme environments [9]. ND additives have been shown to reduce friction and wear in both oil-and water-based lubricated systems [9][10][11][12][13][14]. However, the compatibility of NDs with existing lubricant additives, including TCP, is not yet fully understood.…”

Nanodiamonds (NDs) have potential uses in many applications, including as additives for liquid lubricants, where they may be combined with more traditional chemicals to form protective films on sliding surfaces. It has been shown that NDs can function synergystically with tri-cresyl phosphate (TCP) to facilitate film formation on air baked iron. Here, reactive molecular dynamics simulations of TCP and NDs on an amorphous iron oxide surface reproduce experimental observations of the temperature at which film formation begins with NDs present and the effect of NDs on film composition. Analysis of chemical bonding in the simulations shows that the film formed in the presence of NDs is comprised of NDs and TCP that are both directly and indirectly bonded to the surface. Notably, the amount of phosphorous in the film, which is important for surface protection, is increased by TCP molecules that are indirectly bonded to the surface via NDs, which suggests that indirect bonding is one mechanism by which NDs facilitate film growth. The synergy of NDs and TCP has important implications for the development of NDs as emerging lubricant additives which must function with existing additives such as TCP in many applications.

“…In a twin-disk tests that apply with a contact stress of 1.1 GPa, lubricant added with 0.01 wt% of SWCNTs promising a highest result of wear resistance [25]. As a conclusion, additive of CNT in lubricant oil poses a reduction in the friction coefficient down to 80% as the concentration of 0.5 wt% [24]…”

Milling process is a major machining process used in various type of industries. This process is used to manufacture components such as impellers and structural parts in aerospace industry. Several problems can be arising during the machining operation because 99% of work done produces heat to the chip, the tool and also the workpiece . The temperature of the tool may rise up to 1000oC and this could lead to accelerate the tool wear rate and also the finishing of the surface of the workpiece. In order to improvise this phenomenon, various type of cutting fluid is used in milling operation to use to reduce the temperature of the workpiece. In general, the fluids are used when cutting the workpiece to lower the heat generated at the interface of the tool chip and also the friction on the workpiece. There are four main types of cutting fluid when commonly found in the market which is straight oils, synthetic fluids, soluble oils and the semi-synthetic fluids. This paper is reviewing on the additive for lubricant and their tribology properties.

“…Liquid lubricants are of great importance for friction pairs because of their abilities to reduce COF, wear, contamination, and eliminate excess heat of the systems. However, suitable additives are needed to enhance the certain properties of liquid lubricants such as the wear resistance, oxidation resistance, and anti-corrosion [ 69 ]. Many additives such as carbon-based particles [ 70 , 71 , 72 , 73 ], metal composite nanoparticles [ 74 , 75 ], metal oxides [ 76 , 77 ], and MoS 2 [ 78 , 79 ] have been studied during the last few decades.…”

Owing to the diverse composition, adjustable performance, and synergistic effect among components, core–shell micro/nanoparticles have been widely applied in the field of tribology in recent years. The strong combination with the matrix and the good dispersion of reinforcing fillers in the composites could be achieved through the design of core–shell structural particles based on the reinforcing fillers. In addition, the performance of chemical mechanical polishing could be improved by optimizing the shell material coated on the abrasive surface. The physical and chemical state of the core–shell micro/nanoparticles played important effects on the friction and wear properties of materials. In this paper, the synthesis methods, the tribological applications (acted as solid/liquid lubricant additive, chemical mechanical polishing abrasives and basic units of lubricant matrix), and the functionary mechanisms of core–shell micro/nanoparticles were systematically reviewed, and the future development of core–shell micro/nanoparticles in tribology was also prospected.
