摘要

AA5754 aluminum alloys are widely used in automotive and marine vehicles due to their high corrosion resistance and excellent weldability. Although primarily a wrought alloy, it has recently gained attention as a casting material. The corrosion behavior of AA5754 varies? Depending on the casting method and microstructure. This study examines the effects of the most commonly used sand and permanent mold casting methods and the addition of 0.3, 0.7, and 1% titanium by weight on grain size and corrosion rate. The reference material was prepared through remelting and alloying processes and subsequently cast into sand and permanent molds. A comprehensive characterization of the samples was conducted using optical spectral analysis, x-ray fluorescence, optical microscopy, scanning electron microscopy, energy-dispersive x-ray spectroscopy, x-ray diffractometry, and electrochemical corrosion testing The findings reveal that grain structure and intermetallic phas formation play a crucial role in determining the corrosion rate.
