The aim of this study was to investigate the eects of two dierent treatments, as-cast setup and solution heat treatment, on the general electrochemical corrosion resistance of Ti7Cu alloy samples immersed in a 0.9 wt% NaCl solution at 25 C. The microstructure was examined by scanning electron microscopy and X-ray diractometry. Corrosion behavior was tested by potentiodynamic polarization curves. Finer martensite and Ti2Cu intermetallic particles were provided by casting and heat treated processes, respectively. The results indicated that only corrosion potential is signicantly more noble in the heat treated sample, but other characteristics are only slightly dierent.
