摘要
Abstract
The oxidation kinetics at 960 ℃ of RTCr28Ni15 and RTCr18Ni4 used for grate in garbage incinerator were studied by weight gain method.The microstructure, cross section, composition and the oxidation resistance mechanism of these two alloys' oxidation films generated after heating at 960 ℃ for 100 h were analyzed by using of XRD, SEM and EDS.The results show that both the oxidation curves of RTCr28Ni15 and RTCr18Ni4 increase fast at the first stage and then slow down,but the oxidation rate of RTCr18Ni4 is faster than RTCr28Ni15.There is no protective oxidation film that forms on surface of RTCr18Ni4, so its oxidation resistance at 960 ℃ is weak.However RTCr28Ni15 is totally oxidation iesistant at 960 ℃ due to the protectiveoxidation film formed on its surface and its oxidation resistance is superior to RTCr18Ni4.关键词
