| 中文摘要 | Natural andalusite powders were heated at high temperature in air allowing mullitization. The mullitized powders were spray-dried and then air plasma sprayed to form mullite coatings. Microstructure and phase composition of the plasma-sprayed mullite coatings were investigated by means of scanning electron microscopy and x-ray diffraction. The effect of spraying power on the microstructure and phase composition of the mullite coatings was investigated. It has been found that spraying power has signif- icant effect on the content of amorphous phase in the mullite coatings. At the same time, good adhesion is reached between the mullite coating and the bound coating (NiCrAlY) and between the bound coating and the substrate. The mullite coating deposited at a spraying power of 22.5 kW is free of cracks. The processes reported here are applicable to preparing mullite coatings used in high-temperature environment. |
