AbstractThe oxidation behaviors of Cu-Cr alloys prepared by powder metallurgy (PM Cu-25Cr), mechanically alloying (MA Cu-20Cr) and magnetron sputtering (MS Cu-20Cr) techniques in 0.1 MPa O-2 at 700 degreesC were investigated. A complex scale composing of CuO, Cu2O, CuCr2O4 and Cr2O3 formed on the PM Cu-25Cr alloy, a continuous Cr2O3 layer beneath a complex scale appeared on the MA Cu-20Cr, but MS Cu-20Cr produced a simple scale including outer layer CuO and inner layer Cr2O3. The mass gain of MS Cu-20Cr is less than that of MA Cu-20Cr, and their mass gains are much less than that of the PM Cu-25Cr. Fined level of the microstructure has a significant effect on their oxidation behaviors in binary two-phase Cu-Cr alloys.
