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......
on the anodic dissolution and cathodic hydrogen evolution of the film. Key words: magnesium alloy; AZ31 alloy; phosphate conversion coating; chromate-free film; corrosion resistance; anodic dissolution; cathodic... of magnesium alloys is normally more negative than its corrosion potential in a chloride containing solution [2], the influence of film-temperature on the anodic polarization appears to be clear in this study......
and Materials Transactions A, 2015, 46(5): 1995-2006. [10] LI D G, WANG J D, CHEN D R. Effects of Sm and Y on the electron property of the anodic film on lead in sulfuric acid solution[J]. Journal of Power... of anodic layers on Pb-Ag anode formed through 72 h galvanostatic polarization in H2SO4 solutions with fluoride ion at different concentrations 图2 Pb-Ag阳极在不同氯浓度H2SO4溶液中恒流极化72 h后氧化膜层表面形貌 Fig. 2......

of passivation. However, when the anodic potential exceeds a certain value, the current rises suddenly to a very high value, suggesting breakdown of the passive oxide film. The potential at which..., and the oxidation products away from the reaction sites through cracks in the passive film [29]. Consequently, when the penetrated Cl- ions reach the metal substrate, they promote local anodic dissolution......

was investigated by SEM and XRD. The results show that the conditions of inside and outside surface have apparent effect on the corrosion morphology of alloy 690. The surface of passive film formed in solution with Cl- is uneven, and a lot of pits can be found. The Cl- of electrolyte has great effect on the structure of corrosion product. The corrosion product film formed in solution without Cl- has......
