In concentrations up to 30%, Cr does not form a dense protective scale on Co-Cr alloys in such environments. The linear rate constants for all the Co-Cr alloys (1 to 30% Cr) were 5 to 7 {times} 10{sup {minus}7} g/cm{sup 2}-s, about one third the rate constant for pure Co. The scale contained very little chlorine, consisting of Co oxides and possibly CoCr{sub 2}O{sub 4}. (DLC)
