| 英文摘要 | The traditional MCrAlY coatings face severe hot corrosion issue under the effect of NaCl. Therefore, Al-gradient NiSiAlY coatings were obtained by multi-arc ion plating and a following annealing. With a further pre-oxidation, a thin layer of dense alpha-Al2O3 was formed on the coating. Subsequently, hot corrosion test was performed on the as-annealed and pre-oxidized coatings at 750 degrees C. The dense alpha-Al2O3 layer formed by pre-oxidation could effectively protect the underlying coating from NaCl-induced hot corrosion and improve the hot corrosion resistance of the coatings. By pre-oxidation, the total mass gain was reduced by 75% from 2.1 mg/cm(2) to 0.4 mg/cm(2) after 168 h of hot corrosion test. |
