Previous workers have shown that the corrosion rate of metals in acid media is frequently much greater under heat-transfer conditions than it is under simple immersion conditions. In the work described here it has been found that the rate of corrosion of a metallic heating surface is critically ...
ashould be the same in soil corrosion as in other environments where ferrous metals are subject to corrosion (although of course the boundary conditions affecting these processes may be quite different). 应该是同样在土壤侵蚀象在其他环境里, 亚铁金属是受腐蚀支配 (,虽然 追猎影响这些过程的边界条件...
transfer resistance (Rct) for monovalent (Na+) and divalent cations (Ca++and Mg++) (0.9 kΩ·cm2and 0.4 kΩ·cm2, respectively). The mechanism of acceleration of corrosion by akageneite is discussed in light of disruption effects of added cations on electrical double layer formed at the ...
To increase the accuracy of the predictions it is necessary to develop models of corrosion fatigue that incorporate the main aspects of the physical phenomena. These aspects of the environmentally assisted corrosion fatigue of metals in aqueous solutions involve electro-chemical processes which include ...
Thus, further research is necessary to evaluate the corrosion behavior of metals in reducing gas atmospheres that contain HCl and H2S. In sulfidizing atmospheres, chromium is considered to be the most beneficial alloying element against sulfidation [17], [18], [19], [30]. Pan et al. [28]...
the permeability of aluminium oxide layers for hydrogen atoms, thereby counteracting blister formation. These findings may improve the understanding of the hydrogen blistering process, are valid for all metals kept under terrestrial ambient conditions, and important for the design of proton irradiation ...
