A rheological model of stress relaxation in a thin lubricant film, which is formed on the friction surface under the influence of the force field of the friction surface in the presence of fullerene compositions in lubricants, was developed. Analysis of the model made it possible to establish that the existence of elastic or viscous properties in surface structures depends on the ratio of two parameters. This is the time of stress relaxation in the structure on spots of actual contact and the duration of stress action on these spots, which is termed the lifetime of an actual contact spot. It was shown that an increase in the sliding rate reduces the time of relaxation of stresses in the surface structure. This is due to the destruction of aggregates in the structure of gel and the appearance of rotational movements of separate units ‒ flocs. An increase in the load on the tribosystem significantly increases the value of relaxation time. This is due to squeezing the viscous component out of the structure of a surface film. It was established that if the relaxation time exceeds the duration of actions of stresses on actual contact spots, the structure of a surface film behaves like an elastic solid. Conversely, if relaxation time becomes shorter than the duration of stress action, the film behaves like a viscous medium. Theoretically, it was shown that in the range of sliding and loading rates, when a film behaves like an elastic solid, a decrease in stresses on actual contact spots does not exceed the values of 1.1‒22.8 %. This property provides the bearing capacity of a film. The development of the model will make it possible to simulate elastic and viscous properties of "stitched" structures and substantiate the rational concentrations of additives to lubricants, as well as the ranges of their use.

“…Polyalphaolefins added with the additive MoS2 resulted in a 40% reduction in the strength value [28]. Singh et al 2019 [29] examined the tribological performance of SAE 10W/40 and SAE20W/40 lubricants with the addition of titanium additives and graphene oxide. These additives can reduce the friction coefficient by 32%.…”

The engine movement mechanism is a system composed of machine elements that contact or rub against each other between these surfaces. Surfaces that rub against each other will cause a friction force that causes wear on the surface, so it requires energy to fight the friction force. Lubricants are needed to reduce friction and reduce wear rates, where lubricants are generally made of mineral materials. Lubricants made from synthetic materials are non-renewable and cause environmental problems. The development of biolubricants as lubricating materials based on animal fats or vegetable oils is continuously being carried out. This study aims to observe the potential of biolubricants based on reviews from various previous research journals. The use of additives in biolubricants is also studied whether the addition of these additives can improve the characteristics of biolubricants. This study shows that the addition of certain additives to biolubricants can improve the characteristics of biolubricants.

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.
