《Si对MCrAlY涂层微观结构及性能的影响(英文)》
Three kinds of Co Cr Al Y alloy powders with Si mass concentrations of 2%and 5%were designed and prepared by VIGA-16 vacuum atomization furnace in the study.Their chemical composition is listed in Table 1.The Co Cr Al Si Y coating,in a thickness about 0.2 mm,was prepared on a GH907substrate in a diameter of 22 mm by using GTV-K2 high velocity oxygen fuel apparatus.A constant oxidation test at 1050°C was performed in a muffle furnace.An automatic cycle thermal shock test machine was applied to investigate the coating thermal shock resistance at 1050°C.After keeping for 10 min in the high temperature test facility,the samples were taken out and quenched in(20±5)°C water for 1 min.For each thermal shock cycling step,the sample appearance was photographed.In addition,scanning electron microscopy(SEM)was used to gain knowledge of the micro structure and surface oxide film of the alloy powder and coatings.The distribution of different elements in the powders was analyzed by EDS.
