Aluminum and carbon fiber reinforced polymer matrix composites (CFRP) are typically considered corrosion resistant when used alone, but can develop severe galvanic corrosion when in physical contact in the same component or structure.Hakansson, Eva...
We try to use nickel plating on our aluminum part (6061 or 5052) for corrosion protection. But the position between nickel and aluminum in Galvanic index (anodic index) is quite far. If a galvanic corrosion will happen between them. Normally electrode reaction occurs when water or other electr...
The corrosion of an aluminum alloy (Al2024) and copper in 0M HCl solution was investigated at 30, 40, 50 and 60 °C using open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) measurements. The galvanic corrosion of Al2024 and copper ...
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...

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:...
fiberglass washers and bushings to keep the titanium from touching a metal bolt & nut, all of the materials would be electrically isolated from each other so galvanic corrosion could not occur. But then the question, for me, becomes: "What is the purpose of the titanium and the aluminum?"...
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)...
Galvanic corrosion sensitivity of 2024 and 2124 aluminum alloys connected with high potential titanium alloy(TC4) to speed up corrosion was compared to the anodized aluminum alloy by measuring the current distribution curves of galvanic corrosion.By observing the surface morphology after corrosion,the gal...
