“…Therefore, the presence of Ag element indicates the AgNPs were deposited on both worn surfaces [26]. This result confirmed formation of tribofilm on the contact area between ball and substrate materials [35,50,51]. And it might be said that tribofilm was occurred on a large surface instead of partial regions for Oil-Ag@Ctr and Oil-Ag@Pva lubricants [52].…”

In recent years, studies have shown that using nanoparticles (NPs) as lubricant additives lead to the enhancement of the anti-wear behaviour of oils. In this study, the anti-wear behaviour of silver (Ag) NPs which were capped with polyvinyl alcohol and sodium citrate were investigated for three different sliding speeds (2, 3 and 4 mm s−1) under two different loads (30 and 50 N). Results show that the AgNPs led to a decrease in friction and wear due to the formation of a tribofilm and a rolling effect. However, influence of the AgNPs declined at higher loads while increasing at higher speed test conditions. Also, both stabilising agents underwent disordering of AgNPs morphology and size successively under the applied loads.

“…Table 7 compares the results obtained from the study with existing studies conducted on fully formulated oils and chemically modified bio-oils. [26][27][28][29][30][31][32] It is concluded that avocado oil mixed with ZDDP is a serious candidate for the replacement of petroleum-based mineral oils.…”

The paper aims to study the antiwear (AW) and extreme pressure (EP) properties of avocado oil mixed with zinc dialkyl dithiophosphate (ZDDP) in concentrations of 1% to 3% by weight for lubrication purposes. The AW and EP tests are conducted as per ASTM-4172 and ASTM-2783 standards respectively. Further, the rheological behavior of avocado oil mixed with ZDDP is determined for varying shear rates of 50 – 2000 s−1. The maximum improvement in the wear properties for avocado oil is equal to 39.8% at 1 wt.%. The load wear index of pure avocado oil increases from 32.6 to 80.3 at 3 wt.% ZDDP whereas, the weld point increases to 252 kgf at 3 wt.% ZDDP. The improvement in the antiwear and extreme pressure properties are attributed to the protective film formation on the tribopairs as characterized by SEM and EDX analysis. Also, the addition of ZDDP increases the viscosity of the oil at all concentrations and maintains the Newtonian behavior of oil.

“…During tribological interactions, Ag nanoparticles form a thin tribofilm layer on the wear surfaces [60] (both cutting tool and workpiece). This tribofilm mechanism was found to be responsible for improving the tribological characteristics of the nanoparticles incorporated metal working fluids [61]. The Ag nanoparticles present in the metal working fluids tend to fill the wear cracks [62].…”

Research investigations conducted in the past has shown that conventional petroleum based lubricants can be replaced with vegetable lubricants. Vegetable oil lubricants do not pollute the environment, as they are biodegradable. In this investigation, pongamia pinnata oil was used as lubricant, to during turning experiments. The physico chemical properties of modified pongamia pinnata oil were evaluated. Ag Nanoparticles were incorporated into the modified pongamia pinnata oil and it was subjected to tribological investigations. In this investigation, the effect of Ag nanoparticles in improving the lubricating aspects of the modified pongamia pinnata oil was studied. The aim of this investigation is to identify the effect of the nanoparticle incorporated bio- lubricant coolant on Monel K 500. In this study, using TiAlN coated triangular tungsten carbide inserts, Monel K 500 was subjected to turning under three conditions such as dry, minimum quantity lubrication and Ag nanoparticles incorporated vegetable oil lubrication. It was observed that the properties of the bio lubricant affected the turning output responses to such as cutting force, machining temperature, tool wear and surface roughness of the workpiece (Monel K 500). Machined surface was evaluated using scanning electron microscope, electron back scatter diffraction analysis and X-Ray diffraction analysis. Turning operation conducted with 2% Ag nanoparticles incorporated modified pongamia pinnata oil lubrication was better than turning conducted under dry and lubricated conditions. Industrial wastes and toxic effluents can be minimized by switching over to bio lubricants and coolants.
