Formation process of liquid in interface of Ti/Cu contact reaction couple WU Ming-fang(吴铭方), YU Chun(余 春), YU Zhi-shui(于治水), LI ui-feng(李瑞峰) (Department of Materials Science and Engineering, Jiangsu University of Science and Technology, Zhenjiang 212003, China) Abstract: By using the Ti/Cu contact reaction couples, the dissolution behavior of Ti and Cu in the eutectic reaction process......
Finite element analysis of contact fatigue and bending fatigue of a theoretical assembling straight bevel gear pairDENG Song(邓松), HUA Lin(华林), HAN Xing-hui(韩星会), HUANG Song(黄松)(School of Automotive... of a theoretical assembling straight bevel gear pair to analyze the contact fatigue on the tooth surface and the bending fatigue in the tooth root. Based on the cumulative fatigue criterion and the stress-life......
in the tested pH range with an IEP less than pH 2.5. 4.2 Surface free energy of pyrite mineral and thiobacillus ferrooxidans The measured contact angles of the three liquids on the surface of pyrite...; Abstract: Electrokinetic and contact angle measurements were used to discuss the interfacial interaction on bio-leaching of pyrite mineral. Surface energy parameters of pyrite......
-assembled monolayers, the contact angles tend to smaller as the increment of the spacing of surface texture, and tend to bigger as the increment of the height of surface texture. Maximum contact angle of 156° and the super-hydrophobic surface can be acquired. After laser manufacturing and preparing hydrophilic APS self-assembled monolayers, the contact angles tend to bigger as the increment......
