Abstract

The isothermal oxidation kinetics of as-cast Cu–17%Cr and Cu–17%Cr–5%Al in air were studied between 773 and 1,173 K under atmospheric pressure. These observations reveal that Cu–17%Cr–5%Al oxidizes at significantly slower rates than Cu–17%Cr. The rate constants for the alloys were determined from generalized analyses of the data without an a priori assumption of the nature of the oxidation kinetics. Detailed analyses of the isothermal thermogravimetric weight change data revealed that Cu–17%Cr exhibited parabolic oxidation kinetics with an activation energy of 165.9 ± 9.5 kJ/mol. In contrast, the oxidation kinetics for the Cu–17%Cr–5%Al alloy exhibited a parabolic oxidation kinetics during the initial stages followed by a quartic relationship in the later stages of oxidation. Alternatively, the oxidation behavior of Cu–17%Cr–5%Al could be better represented by a logarithmic relationship. The parabolic rate constants and activation energy data for the two alloys are compared with literature data to gain insights on the nature of the oxidation mechanisms dominant in these alloys.

Notes

  1. All compositions reported in this paper are in wt.% unless otherwise noted.

  2. This magnitude of A includes the sum of the areas of the two faces, the area of the outer edge of the specimen and the area of the specimen edge at the hole.

  3. It is noted that t = 0 in this paper corresponds to the time at which the test temperature is attained.

  4. In this paper, the subscripts ‘m’, ‘p’ and ‘q’ denote generic, parabolic and quartic relationships, respectively.

  5. The parabolic rate constants show in Fig. 7 were determined from relatively short term tests lasting less than 24 h in most of the investigations. As shown in this investigation, oxidation to longer times can result in a change in the oxidation kinetics especially in Cu alloyed with Al.

  6. The terms “single” and “double” layers refer to the ideal scale morphologies consisting of either only a Cu2O layer or a combination of an outer CuO layer over an inner Cu2O layer, respectively.
