“…18 This friction, in turn, affects engine durability as well as fuel consumption. Therefore, various methods are used to improve the performance of automotive engines such as coatings, 19 laser texturing, [20][21][22][23] reducing the weight of components and modifying the composition of automotive lubricants. 24 Thus engine oil having high lubricity is needed to reduce friction and wear in order to extend engine life.…”

“…Currently, much research has been reported to increase lubricity of ultra-low sulfur diesel (ULSD). Important techniques like coatings, texturing 10 and addition of antiwear agent can be mentioned. The addition of an antiwear agent may be the most effective way to solve the lubricant problems and recent researches have focused in carboxylic acids, amides, alcohols, ether and biodiesel like antiwear agents 11 .…”

The mineral diesel oil sold in Brazil, due to environmental reasons; presents sulfur concentration of 10 ppm, which causes a deficiency of lubricity, since sulfur is one of the chemical species that gives a good lubricating characteristic. Poor lubricity affects performance and causes failure of engine parts. This study aimed to evaluate the use of glycerin as an antiwear additive by means of tribological tests of the mineral diesel S10 B7 and 10 formulations of diesel based fuels, micro emulsified with 0% (distilled water), 7.5% and 15% of glycerin solution. The formulations were subjected to lubricity tests on HFRR (Hight Frequency Reciprocating Rig) under hydrodynamic lubrication conditions, according to the ASTM D-6079 standard. The results showed that the increased concentration of glycerin added to diesel S10 B7 contributes to improved lubricity and wear reduction.

“…Another emerging technique, patterned thin solid film technology, combines a thin solid film technology with surface pattern technology and is considered an effective method to further improve the tribological performance . A report by Chen et al on the tribological performance of stamping die steel showed that both the triangle texture and TiN films were effective at reducing friction and wear, which resulted from the high hardness and elastic modulus of the TiN films, the hydrodynamic pressure, and the micro‐trap from the surface pattern for wear debris.…”

This paper describes an experimental investigation into the influence of the stripe interspace and applied load on the tribological behavior of stripe patterned TiN films. The stripe patterned TiN films are deposited on an H13 steel surface by masked deposition with the filtered cathodic vacuum arc discharge (FCVAD) technique. The surface micro morphology, chemical composition, crystal structure, and mechanical properties of the films is characterized using 3D white light interferometry, scanning electron microscopy (SEM), X-ray diffractometry (XRD), and a nano-indentation tester, respectively. The tribological performance of patterned TiN is measured using a UMT-5 tribometer, and the friction and wear mechanisms are analyzed, compared with that of the full TiN film and H13 steel substrate. The results show that the stripe patterned TiN films has better tribological properties than the full TiN film. These results are attributed to the synergistic effect between the surface pattern and the TiN film. The stripe interspace and the applied load has a more significant effect on the wear rate of the stripe patterned TiN films than the coefficient of friction of their friction pairs. A further study, however, is needed to analyze the relationship between the applied load and the wear rates of the stripe patterned TiN films.
