The Influence of Humid Environment on Fatigue Property of Pre-Corroded 7XXX Aluminum Alloy

“…These studies include pre-corroded fatigue in a single environment or a combination of all kinds, corrosion fatigue in the interaction between a single environment or a combination of all kinds and load spectrum, corrosion fatigue after pre-corrosion and so on. In China, although the influence of corrosion on fatigue life of aluminum alloy has been studied [8][9][10]3]by many scientists and engineers, very few research on the influence of pre-corroded damage on fatigue life has been reported. For instance, the fatigue and corrosion fatigue study on pre-corroded LY12CZ aluminum alloy, by Zhang Youhong [4] and Kuang Lin [11] et al The study obtained S-N curves, and established the relationship between corrosion damage and fatigue life.…”

Crystal Structure and Dielectric Characterization of a (SrTiO3/BaTiO3) n Multilayer Film Prepared by Radio Frequency Magnetron Sputtering

“…[11] Ferroelectric multilayer thin films, such as PbTiO 3 /Pt/ PbTiO 3 ultrathin multilayer capacitors, have been prepared by a sol-gel process. [12] Qu et al [13] reported that the dielectric properties of BaTiO 3 /SrTiO 3 superlattices are significantly different from those of Ba 0.5 Sr 0.5 TiO 3 solid solution thin films. O'Neill et al [14,15] pointed out that the relaxer behavior was observed in multilayer BaTiO 3 /SrTiO 3 thin films deposited on Pt/Si substrates with periodicities ranging from 1.6 to 40 nm and a total thickness of 400 nm.…”

Preparation and characterization of SrTiO3/BaTiO3 thin multilayer films deposited on Pt/Ti/SiO2/Si substrate by radio frequency magnetron sputtering

“…Preparation of the dielectric superlattices of BaTiO 3 /SrTiO 3 containing thin layers of BaTiO 3 and SrTiO 3 can be accomplished alternative attachment by a multitarget pulsed laser deposition technique onto sapphire substrates without Pt/Ti electrodes [12] and by the alternating evaporation method using an atomiclayer-epitaxy control system for molecular beam epitaxy [13] have been reported. The ferroelectric multilayer thin films such as PbTiO 3 /Pt/BaTiO 3 ultrathin multilayer capacitor by the sol-gel technique have been reported by Bao et al [14]. However, preparation the SrTiO 3 /BaTiO 3 thin multilayer on Pt/Ti/SiO 2 /Si substrate by a double target RF magnetron sputtering have not been studied in detail.…”
