The effect of element S on the corrosion behavior of nickel-base alloy G3 was analyzed and discussed by the following technologies, such as SEM, EDS and XPS. The results show that the average......
with that of pure Pb and alloy I. Thus, it can be established that the formation of passive layer of lead oxide on the alloy surface requires a larger over-potential than that on pure lead [33..., BUI N, SIMON P, ALBERT L.

, pitting corrosion is observed on the surface passive film of Ti–6Al–4V ELI alloy but is not found on that of TNTZF alloy. The XPS analysis results reveal that the passive film formed on TNTZF alloy..., and the minor peak at 531.8 eV corresponding to hydroxyl groups, OH- [24]. Based on the results of XPS, the passive film formed on the surface of Ti-6Al-4V ELI alloy is predominately TiO2......
1.2. At the same time the mass of magnesium alloy is maintained as a function of the time. When the ratio is above 1.4, the mass of magnesium alloy rapidly decreases. The passive film formed through adsorption of HF2- (or H2F3-, H3F4-) ions by the deposited MgF2 film can protect the magnesium alloy from corrosion in fluoride solution, but not in non-fluoride solutions. The passive state......
