| 中文摘要 | NiCoCrAlY coatings were prepared on superalloy K4I7G using arc ion plating (Alp), then some specimens coated with NiCoCrAlY were aluminized using a pack cementation method. The high temperature oxidation and hot corrosion behavior of the ordinary and the aluminized NiCoCrAlY coatings were studied. The results indicated that alpha-Al(2)O(3) scales grew on both coatings during oxidation at 1000 degrees C and 1100 degrees C in air, and the aluminized NiCoCrAlY coating always showed lower oxidation rates and lower degradation rates. The hot corrosion tests were carried out by applying salt films of 25 wt.% K(2)SO(4)+ 75 wt.% Na(2)SO(4) mixture on the specimens and exposing in air at 900 degrees C. The aluminized NiCoCrAlY coating showed a longer lifetime by forming a continuous Al(2)O(3) scale. But, cracks and spallation of the oxide scales occurred on the ordinary NiCoCrAlY coating after 80 h. (C) 2011 Elsevier B.V. All rights reserved. |
