The effects of agitation velocity (0–1000 rpm corresponding to Reynolds number of 0–299,000), CO2 gas flow rate (0.34–1.6 m3/h), temperature (30–50 °C), and time on galvanic corrosion current and loss in weight of both metals in both free corrosion and galvanic corrosion were ...
Aluminum adjoins zinc in the galvanic series. Decision makers are often aware that aluminum’s corrosion rate in atmosphere is between that of carbon steel and stainless steel, but, when it is directly coupled to another metal and an electrolyte is present on a regular basis, it becomes very ...
Therefore, the self-corrosion of anodized 7050 Al and LHE CdTi plated 300M steel dominated the corrosion process. The pitting and intergranular corrosion (IGC) of the anodized Al were severe, and significantly reduced the strength and elongation. The corrosion products composed of AlOOH, Al(OH)...
For example, zinc will corrode in saltwater extremely quickly when in contact with platinum, but 304 stainless steel in contact with 316 stainless steel will have little effect on each other. Here's an example of galvanic corrosion between carbon steel and aluminum in sea water: By Webcorr –...

Passive film is formed on the surface of aluminum, chromium, silicone and titanium in air, water and dilute acids. Good corrosion and oxidation resistance of Stainless steels is also a result of formation of chromium reach oxide passive layer. The passivation effect is achieved if the chromium ...
Galvanic corrosion is caused by an electrochemical reaction between different classifications of metals rubbing against each other in wet or grimy conditions. This type of corrosion commonly occurs between aluminum and cast iron; copper and steel; and stainless steel and aluminum. ...
galvanic corrosion between CFRP/aluminum alloy couple on the corrosion behavior of CFRP and aluminum alloy,SEM technique was used to study the morphology of the surface corrosion.The results showed that galvanic corrosion promoted the formation and propagation of the pitting corrosion of the LY12CZ ...
