Electrodeposited Fe-Cr alloys show amorphous structure and better corrosion resistance when the Cr content of the films is more than 30wt%.
Research with controlled plating conditions-e.g. bath pH, current density and bath composition-have been performed and the alloys are definitely introdeced to show how these factors affect the amorphous sturcture of the deposited films.
In addition, by taking the results of electrochemical measurement into account, some difference in corrosion between amorphous and crystalline Fe-Cr alloys have been recognized. The amorphous structure was observed to be passivated in 0.1N H2SO4 solution.
