“…The linear speed and radius of the wear track were 50 mm/s and 14 mm, respectively. It should be noted that a relatively low sliding speed hereby was selected to minimise the hydrodynamic effect on testing results [19,20]. During testing, the time histories of COF were recorded.…”

The tribocorrosion behaviour of two different hull steels (namely, EH36 and EH47) was investigated using a ball-on-disk tribometer under varying normal loads from 10 to 100 N in a 3.5 wt% NaCl saline solution. Sliding in pure water was also performed for a comparison purpose. The results indicate that the corrosion products mainly consist of lath lepidocrocite (γ-FeOOH) with residual NaCl crystals when sliding against both steels EH36 and EH47 in the saline solution. Tribocorrosion on EH36 (pearlitic steel) shows lower coefficient of friction (COF) values than those obtained in water, while tribocorrosion on EH47 (bainitic steel) leads to higher COF values instead. The former is due to the formation of considerable hydroxide particulates and films with small sizes. In contrast, the latter is ascribed to the ploughing of hydroxides with smaller amounts and bigger sizes. In particular, the synergistic effects of corrosion and wear in tribocorrosion result in much higher total materials degradation, compared to that obtained through pure mechanical wear in water.

“…Wu et al doped nano TiO 2 into water-based lubricants and found that 4.0 wt% TiO 2 in lubricant achieved the lowest friction coefficient (COF) on both clean and preoxidized steel disks, which was attributed to the formation of tribofilm and ball-bearing effect, respectively [24] . They also found that TiO 2 contained water-based lubricant applied in steel friction pairs, had different effects and tribofilm with elevating temperatures [25] . Ge et al synthesized new greases by using oleophilic nano-TiO 2 as additive, with good tribological characteristics, and they ascribed it to the nanoparticles mechanical effect and the protect film generated by Ti deposited or metallic oxide [26] .…”

The tribological behaviors of core‐shell n‐octadecane@TiO₂/epoxy composites

et al. 2020

In this work, the n-octadecane@TiO 2 particles with core-shell structure were successfully prepared via a sol-gel method in an oil-in-water (o/w) emulsion. The resultant core-shell particles were incorporated into epoxy matrix to prepare composites. Compared with pure epoxy and TiO 2 doped epoxy, the incorporation of n-octadecane@TiO 2 reduced the friction coefficient (COF) and wear rate of epoxy. According to the systematical investigation of the wear tracks on three samples and scars on their friction antithesis balls, it was speculated that the antifriction effect of core-shell additives on composites were mainly attributed to the mixture formed by the crushed n-octadecane@TiO 2. The mixture not only backfilled the tearing-like cracks on worn face generated by fatigue wear, but also promoted the formation of transfer film.

This research is aimed at studying the stability and tribology properties of the polyol ester oil- (POE-) based biolubricant mixed with various filler loadings from microparticle of TEMPO-oxidized bacterial cellulose (NDCt) as an additive and sorbitan monostearate (Span 60) as a surfactant. Morphology, rheology, and tribology tests were conducted. The addition of NDCt and Span 60 to pure POE as a base fluid showed elevated viscosity, lower value of coefficient friction (COF), and a remarkable decrease in the wear rate (WR). The presence of 0.6 wt% NDCt and 1.8 wt% Span 60 in POE (N2S4) decreased the COF value by 79% in comparison to POE. At room temperature, this N2S4 biolubricant sample showed a higher thermal conductivity by 4% and lower WR value by 49% compared to POE. This study introduced the preparation of the ecofriendly biolubricant filled with NDCt improving the tribology properties remarkably.
