novel uses of sio2 nano Lubrication System in hard turning process of hardened steel aisi4140 for less tool wear surface roughness and oil consumption
Journal of Cleaner Production, 2014Co-Authors: M Sayuti, Ahmed A D Sarhan, Faheem SalemAbstract:Abstract Hardened steel AISI 4140 material is commonly used to produce automotive parts such as shafts, gears and bearings. Machining this material significantly increases the temperature in the cutting zone and is critical in deciding workpiece quality. Though cutting fluids are widely employed to dissipate the heat in machining, they threaten the ecology and health of workers. Hence, there arises a need to identify eco-friendly and user-friendly alternatives to conventional cutting fluids. Modern tribology has facilitated the use of a nano-Lubrication System. For this purpose, a novel uses of nano-lubricants in minimum quantity Lubrication (MQL) System were studied. In the present work, a mist of SiO2 nano-Lubrication was used and applied by air pressure in turning of hardened steel AISI4140. In this research work, the optimum SiO2 nano-Lubrication parameters to achieve correct Lubrication conditions for the lowest tool wear and best surface quality were investigated. These parameters include nano-lubricant concentration, nozzle angle and air carrier pressure. The Taguchi optimization method is used with standard orthogonal array L16(4)3. This research is investigating on the new and novel uses of SiO2 nano-lubricant by conducting analysis on tool wear and surface roughness using fuzzy logic and response analysis to determine which process parameters are statistically significant. Besides, these analyses were conducted in order to prove the effectiveness of nano-lubricant. Finally, confirmation tests were carried out to investigate optimization improvements.

Influence of surface topography on frictional properties of Cu surfaces under different Lubrication conditions: Comparison of dry, base oil, and ZnS nanowire-based Lubrication System
Tribology International, 2011Co-Authors: Vinay Narayanunni, Bassem A. Kheireddin, Mustafa AkbulutAbstract:This work deals with the frictional properties of ductile Cu surfaces of varying morphologies under three different Lubrication conditions including dry, base oil only, and nanowirebase oil. It was found that the frictional properties of base oil and nanowire-based Lubrication System strongly depended on the surface topography while the friction for the dry surfaces was independent of the surface topography. © 2011 Elsevier Ltd.

high speed rolling by hybrid Lubrication System in tandem cold rolling mills
Journal of Materials Processing Technology, 2015Co-Authors: Yukio Kimura, Noriki Fujita, Yukihiro Matsubara, Koji Kobayashi, Yosuke Amanuma, Osami Yoshioka, Yasuhiro SodaniAbstract:Abstract Lubrication is one of the most important factors for improving the productivity of tandem cold rolling mills, as it is possible to increase the rolling speed of thin gauge steel strips and prevent chatter when rolling materials with high deformation resistance. In this study, a new hybrid Lubrication System is proposed and its effectiveness is clarified. The System is based on a lubricant recirculation System combined with a System for flexible Lubrication control. The key to realizing the new lubricant System is control of plate-out oil film formation on the strip surface under high-speed rolling conditions. The plate-out oil film formation of emulsions is investigated, and the conditions for achieving a sufficient plate-out oil film are clarified. The time-dependent property, oil droplet size, and emulsion concentration are found to have significant effects on plate-out behavior. In addition, the conditions for practical application of hybrid Lubrication Systems are discussed from the viewpoint of realizing effective plate-out control. A new hybrid Lubrication System was investigated, and it successfully enabled flexible controllability of Lubrication conditions and achieved the high-speed stable rolling, while maintaining an oil consumption rate equal to that of recirculation Systems.
