Abstract

The results of corrosion resistance of aluminum alloy 5754 used as a construction material in the automotive industry has been presented in the paper. The samples of aluminum alloy were exposed to acetic salt spray, containing copper chloride as a corrosion initiator, according to ISO 9227: 2012 and the following methods: linear polarization, potentiodynamic cyclic voltametry according to PN-EN ISO 10271: 2012 and impedance spectroscopy according to PN-EN ISO 16773: 2009. In order to correlate the tests as a corrosive environment at temperature 50 °C acetic salt solution was used. Obtained results have been developed in terms of corrosion mechanism, extension and type of acetic corrosive environment. It has been found that tested material is not resistant to corrosion in a acetic acid corrosion environment. The literature research shows that aluminum alloy 5754 has good corrosion resistance properties which are required for many structural components in the automotive industry.
