The oxidation of Cu--Si and Cu--Al alloys was studied in air at temperatares from 600 to 1000 deg C. The isothermal oxidation law was found to be parabolic. The heat of activation of Cu--Al was measured as 35,700 cal/mole by the gravimetric method and 34,900 cal/mole by the micrographic method. The heat of activation of Cu--Si was found to be 35,900 and 35,800 cal/mole by the gravimetric and micrographic methods, respectively. The mechanism of the oxidation of cuprous oxide to cupric oxide was determined. (J.S.R.)
