Influence of surface liquid segregation on corrosion behavior of semi-solid metal high pressure die cast aluminium alloys

摘要：

The corrosion behavior (in chloride medium) of the surface layer of SSM-HPDC plates of alloys 7075-T6 and 2024-T6 was compared with that of the wrought alloys 7075-T6 and 2024-T6. Potentiodynamic testing was performed in deaerated 3.5％NaCl solution. In separate tests, the opencircuit potential was monitored in aerated 3.5％ NaCI for 30 min after immersion. The electrochemical tests show that there is no significant difference in the pitting potential of the wrought alloys and that of the Cu-enriehed surfaces of the SSM-HPDC alloys.
