Properties and Performance of Compositionally Complex AlCrFeMn Alloys for Marine Applications

Project: Research project

Project Details


Funds are provided to develop CCAs with commodity metals, such as Al, Zn, Fe, Mn, Cu, Si, Sn experimentally in combination with ther''modynamic calculations, and produce cheap systems based on combinations of mentioned elements that are Ni- or Co- free using variati''on of Cr or Ti, respectively; evaluate corrosion properties using cyclic polarization and exposure testing in addition to in-depth e''lectrochemical analysis; characterize passive film properties using surface characterization tools, such as X-ray photoelectron spec'troscopy (XPS) and Auger electron spectroscopy (AES); and elucidate the feature that govern corrosion resistance of CCAs made of relatively inexpensive alloying elements.The deliverables will be the scientific understanding of the properties and microstructures o'f the CCAs, and newly designed and produced CCAs that are empirically tested.
