Abstract
Until recently the brittleness of chromium and its alloys has limited their use in applications which require a high resistance to corrosion in oxidising environments. Now, minor additions of selected metals can produce alloys with satisfactory low temperature ductility and workability, but even these alloys are susceptible to corrosion in non-oxidising environments. Passivation and corrosion resistance in such conditions can be increased by cathodic additions of noble metals; this paper reports a study of the effects of such additions on the corrosion and electrochemical behaviour of ductile chromium alloys in non-oxidising environments.
