test and immersion method, respectively. The microstructures of the original and corrosive samples were observed by SEM and their chemical compositions were analyzed by EDS. The results show......
chemistry of aluminium and magnesium leads to the high sensitiveness to the pitting corrosion and failure in the corrosive environments, threatening the long-term and safe operation and service......
materials with enhanced high-strength properties, considerable attention now also has to be given to their chemical stability in corrosive media. Therefore not only examples of the use of high......
polarization tests. The corrosion resistance enhancement was attributed to the film compactness (due to the chemical interaction with the HNDs), formation of tortuous pathways for diffusion of the corrosive... coatings typically contain many structural defects (such as cracks, pores, and parts with low cross- linking density) that allow the corrosive agents to penetrate toward the film/metal interface. Cracks......
because of the increase of Cl-concentration at pH 4,and Cl-acted as a catalyst in the corrosive medium at pH 6 because the net H+concentration decreased obviously compared with the condition......
encapsulated LEDs and microelectronics. As the water and corrosive constituents play a crucial role in their reliability, water uptake kinetics, interfacial ion transport and delamination behaviour of silicone......
g/L and Na2B4O7·2H2O 20 g/L. The results show that the corrosion resistance of AZ31magnesium increases with the increase of pH value of the corrosive medium. For the chemical conversion layer... resistance of AZ31 magnesium alloy, increases with the increases of pH values of corrosive medium. It can be seen in Fig.2 that the EIS plots of magnesium consist of a capacitive arc in high frequency......
current density, decreased by two orders of magnitude as compared with the magnesium substrate. Meanwhile, the corrosive potentials of the coated samples increased nearly by 73 mV. EIS result showed... and the size of the micropores (Fig. 2(a)) was less than 3.2 μm, indicating a dense and smooth surface of the coating, which can prevent the corrosive medium from penetrating into the magnesium alloy......
