The kinetics and products of oxidation of binary Co-5Si alloys in 1 atm of pure O2 at 700 and 800 oC were investigated. Co-5Si alloys followed a parabolic behavior to a good approximation (n=2). The parabolic rate constants as functions of temperature were 2.789×10-11, 2.240×10-10 g2cm-4s-1 at 700 and 800 oC, respectively. The scales formed on Co-5Si alloys were double-layered, with formation of an outer layer of columnar CoO and an inner region containing a mixture of SiO2 and CoO, coupled to the internal oxidation region of Si.
