, China摘 要:<正> A lubrication model was developed for explaining how to form an oil film in the deformation zone, predicting the film thickness... 0.032 to 1.6 Pa·s were used to obtain different film thicknesses in the strip cold rolling. Results from the experiment and calculation show that the oil film forming in hydrodynamic lubrication is up......
"><正>The effects of oil film on the rolled surface,including surface roughness and topography,were investigated during cold rolling of aluminum strips.Various mineral oils with viscosities from 0.10 to 1.6 Pa.s were used to obtain different oil film thick- nesses.Results from experiment and calculation show that the thicker oil film protects the initial roughening surface so that it leads......

Electrochemical Intercalation of Sodium into Silicon Thin Film Gyu-Bong Cho1,Dong-Yeon Kim1,Jou-Hyeon Ahn2,Ho-Suk Ryu1,Ki-Won Kim1,Won-Cheol Shin3,Hyo-Jun Ahn1,Jong-Seon Kim1 (1.I-cube center nano... lnc, Gyeonggi Technopark, 1271-11 Sal-dong, Sangnok-gu, Ansan-si, Gyeonggi-do 426-901, Korea) 摘要:In order to investigate the possibility of Si thin film as an anode for Na battery, we studied......
Melt film formation and disintegration during novel atomization process LIU Yun-zhong(刘允中)1, K. Minagawa2, H. Kakisawa2, K. Halada2 1. School of Mechanical Engineering, South China University.... The key concept of hybrid atomization is to control the liquid film formation on disk for fine powder production. Low-pressure gas atomization was utilized to promote the formation of a very thin......

, which demands that the lubricant must spread quickly on the virgin surface between the working interfaces, and become a layer of uniform lubricating thin film to cover effectively the virgin surface... and its shadow looked like a convex glass. The diameter of the drop increased and the thickness decreased continuously with time evolution, and the drop turned into a thin oil film 3 s later. Obviously......
Film Layer Structure and Wear Resistance on High Strength Room Temperature Blackening of Cu-Se-P System ZHANG Yu-feng1,WANG Jian-cheng1,ZHOU Hou-qiang1 (1.Wuhan Ordnance Noncommissioned Officer School, Wuhan 430075 ,China) 摘要:In this paper,the high strength room temperature blackening film on steel surface were prepared, the structure and the forming principle of the film were studied. The Cu......
