...Wei Wang; Wenhan Zhao; Qiang Ma; Ange Nsilani Kouediatouka; Hui Zhang; Guangneng Dong; Meng Hua; Hon-Yuen Tam The synergistic effect of surface texturing and lubricants with various viscosity and polarity properties is an attractive and unexplored topic. In this study, surface texturing...

...V. Ezhilmaran; N. J. Vasa; Sivarama Krishnan; L. Vijayaraghavan Femtosecond laser-assisted surface texturing of compression piston rings is proposed and demonstrated. A femtosecond pulsed Ti 3+ :sapphire laser is used to generate dimples of the same size but with different area density on a moly...

.... The dimples were assumed to exist on both contact surfaces and the surface shapes of the contact bodies were evaluated separately. It is pointed out that surface texturing due to the micro-dimples is not necessarily beneficial in EHL contacts under fully flooded conditions since the micro-dimples provide...

... of tribological performance caused by textures. hydrodynamic lubrication surface texturing cavitation mass conservation Many essential mechanical elements or components like bearings, gears, piston rings, etc. have to operate in the environment of lubrication. For decades, different versions...

... 18, 2013. Assoc. Editor: Dong Zhu. 18 05 2012 04 11 2012 It has been recognized that purposefully designed surface texturing can contribute to the improvement of tribological performance of elements and friction reduction. However, its optimal parameters may depend...

...B. Podgornik; M. Sedlacek In recent years the efforts to better control friction and wear have focused on surface-topography modification through surface texturing. Although a lot of effort, including experimental and analytical work, has been put into finding the optimal texturing parameters...

...Yonghong Fu; Jinghu Ji; Qinsheng Bi The effect of surface texturing in the form of parabolic grooves on the hydrodynamic lubrication properties is investigated in this paper. Numerical simulation of the pressure distribution of lubricant between a textured slider and a smooth, moving slider has...

...A. Shinkarenko; Y. Kligerman; I. Etsion This paper presents a nonlinear theoretical model to study the effect of laser surface texturing on the tribological performance in soft elastohydrodynamic lubrication. Both geometrical and physical nonlinearities of the elastomer are considered by using...

.... No such an effect of microdent depth on lubricant film shape has been observed in case of negative slide-to-roll conditions when microdents do not cause film thickness reduction regardless of their depths. Obtained results suggest that surface texturing using microdents of an appropriate depth could help...

...Y. Feldman; Y. Kligerman; I. Etsion; S. Haber Microdimples generated by laser surface texturing (LST) can be used to enhance performance in hydrostatic gas-lubricated tribological components with parallel surfaces. The pressure distribution and load carrying capacity for a single three-dimensional...

...Y. Kligerman, Mem. ASME; I. Etsion, Fellow ASME; A. Shinkarenko An analytical model is developed to study the potential use of partial laser surface texturing (LST) for reducing the friction between a piston ring and cylinder liner. The hydrodynamic pressure distribution and the time-dependent...
