after that. The maximum bond strength is obtained at 400 ℃. With increasing the rolling temperature, the rolling reduction of the aluminum layer increases while the steel layer decreases. At a given total rolling reduction, this leads the difference of reduction between aluminum and steel layer increasing. The number of bending and the bond strength increase with increasing the total rolling......
A Review:Structural Oxide Coatings by Laser Chemical Vapor DepositionTakashi GOTOInstitute for Materials Research,Tohoku University摘 要:Yttria-stabilized zirconia and-alumina films were prepared by laser chemical vapor deposition at deposition rates of several hundred micrometers per hour.Moreover,the structural oxide coatings by laser chemical vapor......

The results show: the strongest bond is the Al-Al bond in the segregated cell without containing vacancy, where the Al atomic covalence radius is greater than that of Li atom in the cell......
Chemical Extraction Preparation of Delithiated Cathode Materials of Li-ion Battery闫时建School of Materials Science and Engineering,Taiyuan University of Science and Technology摘 要:A method of conventional chemical reaction to prepare delithiated cathode materials of Li-ion battery was introduced. The cathode material of Li-ion battery was mixed......
South University, Changsha 410083, China Received 10 April 2012; accepted 15 November 2012 Abstract: A series of boron-doped polycrystalline diamond films were prepared by hot filament (HF) chemical vapor deposition on Nb substrates. The effects of B/C ratio of reaction gas on film morphology, growth rate, chemical bonding states, phase composition and electrochemical properties of each deposited......

of orthotropic elastic rock with plane strain conditions are made in derivation of the formulations. A tri-linear bond-slip constitutive law is used for modeling the tendon-grout interface behavior...) are observed under the bearing plate and the bond length proximal end, respectively. However, large values of tensile stresses with the maximum of -434 kPa are formed at the bond length distal end......
