Corrosion of sintered electrical contact materials under the conditions of the tropical marine climate

Conclusions

The results yielded by this investigation into the corrosion properties of composite materials support the hypothesis advanced in [2], according to which their dissolution behavior obeys the principle of independence of electrochemical reactions. At any given potential each phase in a composite corrodes at a rate characteristic of this phase regardless of processes involving other phases. The process of corrosion of each phase is controlled solely by the latter's condition and composition, which in turn are determined by the reaction of the individual components during the manufacture of the material. When the conditions of operation of a composite material and the corrosion resistance of its components, as affected by their interaction, are known, the corrosion of the material can be expected to be determined by the corrosion of its components.
