The Study of Low Surface Energy Fluorocarbon Coatings with Fluor Content Being Lower LIU Xiu-sheng1,ZHONG Ping1,GAO Wan-zhen1 (1.Wuhan Research Institute of Materials Protection, Wuhan 430030 ,P. R. China) 摘要:A kind of low surface energy fluorocarbon coatings from the synthesized fluoro-acrylic resin was developed.The molecule orientation principle of nonpolar and polar functional groups......
results show that uniform laser-induced periodic surface structures (PSS) can be formed with the appropriate pulsed numbers and laser energy density. Electron-phonon coupling coefficient plays an important role in PSS formation in different metals. Surface ripples of Cu are more pronounced than those of Au under the same laser energy density. Key words: femtosecond laser ablation; energy......

Thermal Stability of Surface Layer Microstructures of Commercially Pure Titanium Treated by High Energy Shot Peening ZHANG Yu-juan1,REN Rui-ming1,CHEN Chun-huan1 (1.Dalian Jiaotong University, Dalian 116028, China) 摘要:Commercially pure titanium was treated by high energy shot peening, and annealed at a series of temperatures. The surface layers are characterized by means of scan electronic......
and Department of Physics,University of Science and Technology of China, Hefei 230026, China) Abstract:The investigation of influence of surface effects on the energy spectra of electrons is essential... impinging on a solid or escaping from it suffer losses in the surface layer. The energy loss spectra therefore have contributions from surface excitations. The role of surface excitations is characterized......

, Changsha 410083, China) Abstract: The surface energy, atomic geometry and electronic structures of Al(100), (110) and (111) free surfaces were calculated using the method of supercell and the first-principles pseudopotential plane waves within generalized gradient approximation. According to the calculated surface energy, the structural stability of Al free surfaces from strong to weak......
