摘要
Copper alloys were studied for oxidation resistance and mechanisms between 550 and 700degreesC, in reduced- oxygen environments expected in rocket engines, and their oxidation behaviors compared to that of pure copper. They included two dispersion- strengthened alloys ( precipitation- strengthened and oxide-dispersion strengthened, respectively) and one solution- strengthened alloy. In all cases the main reaction was oxidation of Cu into Cu(2)O and CuO. The dispersion- strengthened alloys were superior to both Cu and the solution-strengthened alloy in oxidation resistance. However, factors retarding oxidation rates seemed to be different for the two dispersion- strengthened alloys.
