“…Polymer Tribology is the branch of tribology that deals with the abrasion, adhesion, shear, deformation, and fatigue of polymer materials when they are in frictional contact. − Hybrid polymers are nowadays used in a wide range of tribological applications, because of their self-lubricating capabilities, acceptable range of wear resistance, low frictional behavior, and good corrosion stability . When 5% carbon nanotubes were incorporated into polymer fiber reinforced materials to make it a better performance hybrid composite, it has been found out that its wear rate decreases but COF increases …”

This review provides a comprehensive and accessible literature review on the integration of nanoparticles into biolubricants to enhance wear and friction regulation, thus improving the overall lubricated system performance. Nanotechnology has significantly impacted various industries, particularly in lubrication. Nanobiolubricants offer promising avenues for enhancing tribological properties. This review focuses on oxide nanoparticles, such as zinc oxide (ZnO), aluminum oxide (Al 2 O 3 ), copper oxide (CuO), titanium dioxide (TiO 2 ), zirconium dioxide (ZrO 2 ), and graphene oxide (GO) nanoparticles, for their ability to enhance lubricant performance. The impact of nanoparticle concentration on biolubricant properties, including viscosity, viscosity index, flash point temperature, and pour point temperature, is analyzed. The review also addresses potential obstacles and limitations in nanoparticle incorporation, aiming to propose effective strategies for maximizing their benefits. The findings underscore the potential of nanobiolubricants to improve operational efficiency and component lifespan. This review aims to provide valuable insights for researchers, engineers, and professionals in exploring and leveraging nanotechnology's potential in the lubrication industry. This review paper explores the basics of tribology along with its significance, green principles, mechanisms, and energy savings because of friction, wear, and lubrication. Condition monitoring techniques are also explored to achieve brief knowledge about maintaining reliability and safety of the industrial components. Recent advances in tribology including superconductivity, biotribology, hightemperature tribology, tribological simulation, hybrid polymer composite's tribology, and cryogenic tribology are investigated, which gives a thorough idea about the subject.

“…This results in the form of a composite which could be monolithic or hybrid depending on the number of constituting reinforcements. 4,5 It has been seen that reinforcement addition has a direct impact on the strength improvement and hardness increase for the aluminium based composites. [6][7][8] Certain automobile and structural applications require strength improvement as well as minimal wear and friction reduction thus increasing the life span of the material part.…”

Aluminium is one of the most widely available metals and its application is seen vastly due to its high strength-to-weight ratio as compared to other metals being cost effective at the same time. Its application is found to be in various structural, automobile and machine industries. But somehow due to its ductile nature, challenging conditions like high-speed applications with minimal wear and friction loss are an important aspect to look forward to. Al6063-based hybrid composites having boron carbide (B4C) 4% wt. and graphite (Gr) 0/2/3.5/5% wt. composites have been fabricated by the stir casting route using K2TiF6 for enhancing the particle dispersion in the metal matrix. XRD, SEM and EDAX results have been obtained for the composites fabricated for characterization. Impact and hardness test results show improvement in the toughness and hardness of the fabricated composites. SEM images of the fractured specimen have been obtained which depict the inhibition of crack propagation due to the boron carbide and graphite reinforcement’s presence. Pin-on-disc wear tests have been carried out considering the L25 Taguchi orthogonal array along with TOPSIS optimization for finding the best and the worst conditions for wear analysis considering the closeness coefficient, C j .

Copper (Cu) composites hybridized with nano-sized reinforcing material are gathering attraction in such fields as automobile, aerospace, and power transmission due to their higher strength. Unlike conventional reinforcing materials, extraordinary mechanical properties and high electrical and thermal conductivity make nanomaterials highly useful reinforcement materials to improve the properties of pristine metals. Over the last two decades, several studies have been conducted to determine the effect of distinctive 2D nanomaterials, such as silicon carbide, aluminium oxide, copper nanotube, and graphene as reinforcement on properties of metal matrices. This study comprehensively reviews the effect of hybrid reinforcements on the mechanical properties of Cu composites having graphene as one of the reinforcements. Also, the contribution of these reinforced nanomaterials composition and their dispersion in the pure Cu matrices have also been explained in detail. In comparison with Cu composites fabricated with a single 2D reinforcement material, composites incorporating hybrid nano reinforcement, exhibit better mechanical behaviour. Additionally, the improvement in mechanical strength would enhance their capability to withstand altering thermal and surrounding environmental conditions.
