Available for download

The work is mainly focused on the corrosion mechanism at low pH (>4) and the order of which the discontinuous and continuous intermetallic phases dissolve. Compositions of each phase, and the area ratio between intermetallic phases and the alpha matrix have been calculated as an average of 20 measurements.

Heavy corrosion ofNi-Al Bronze in an industrial construction operating in seawaterhas given reason to further investigate thecorrosion-propertiesof this alloyin marine environments including the effect of pH.Astudy on the microstructure and phase-composition ofthe alloywas followed by electrochemical tests and surface- and cross section characterization of both the alloy andit's main alloying elements; copper aluminium nickel and iron.Allexperiments were conductedatpH?8 and pH?3-4 in synthetic seawater at room temperature. The electrochemical tests included recording of the corrosion potential andpolarization curves for all the materials included in the work and additionalpotensiostaticpolarization toanodic potentials ofNi-Al Bronze.The results of this workgive clear indications of a strong pH dependency on the corrosion mechanism for Ni-Al Bronze and that nickel and aluminium are the main elements contributing to this dependency.

Key Words: Ni-Al Bronze, Alloy, Microstructure, pH, Seawater, Corrosion

The effect of a uniform magnetic field on the corrosion rate of anodically polarized Ni-Al Bronze in 3,5 wt.% NaCl has been investigated. It was found that the anodic current density increased when magnetic fields of 300 and 1000 mT was applied to the system.
