    Structure and selected corrosion properties of Ni45Mn39Sn11Co5 alloy

  • Original language description

    The structure characteristics of specimens were investigated using optical light microscopy and scanning electron microscopy equipped with EDX detector. The specimen in as-cast state evinced the dendritic structure, which gradually transformed into regular grains after thermal treatment. The structure of specimen after 24 hours of heat treatment at 900°C was formed by a martensitic phase and by the residue of dendritic grains with the increased content of cobalt and decreased content of tin. On the basis of potentiodynamic polarization method the resistance to corrosion of the alloy Ni45Mn39Sn11Co5 was evaluated in the as-cast state and after heat treatment (annealing at 900 °C, during 2, 8, 18 and 24 hours). The sensitivity to pitting was compared mainly by values of depassivation and repassivation potentials of the tested alloy (in 0.1 M NaCl water solution). The resistance to this localized corrosion was slightly lower than for pure nickel (curves between iron and nickel). After hea
