Abstract:
Research and design of different components of molybdenum-cobalt alloy, including Mo-3Co alloy, Mo-6Co alloy, Mo-9Co alloy and pure molybdenum alloy. The weight loss of pure molybdenum alloy, Mo-3Co alloy, Mo-6 Co alloy and Mo-9Co alloy at 400 °C, 600 °C, 800 °C, 1000 °C after 1-hour oxidation was systematically analyzed. Observing the surface of the oxide layer, it was found that the Mo-6Co alloy was vigorously oxidized at 800 °C and 1000 °C to form volatile MoO3. As the cobalt content increased, the weight loss rate of the samples showed a downward trend at different oxidation temperatures. Granular oxides were formed when the Mo-6Co alloy sample was oxidized at 400 °C; when oxidized at 600 °C, scaly oxides were formed; when oxidized at 800 °C and 1000 °C, blocky or flaky oxides were formed. Addition of the element of cobalt can obviously alleviate the oxidation of molybdenum-based alloy specimens at high temperature.
