Abstract

Rapidly solidified 7075 Al alloy ribbons were prepared by melt-spinning. Sintered 7075 compacts with fine-grain microstructure were obtained by spark plasma sintering of the chopped melt-spun ribbons at different sintering temperatures. The corrosion behavior of the sintered 7075 alloy was examined and compared to that of the 7075-T6 bulk by electrochemical and immersion experiments carried out in NaCl solution. Microstructures of the consolidated samples before and after corrosion tests were examined by optical microscope and scanning electron microscope. Ratios of corrosion after immersion tests were measured by an image analyzing software. Results of this study suggest that the sintered material exhibited slightly poorer corrosion resistance than the bulk 7075 alloy and the porosity adversely affect the corrosion behaviors of the sintered material.
