摘要	A MCrAlX-type coating has been prepared by electrospark deposition (ESD) and its isothermal oxidation behavior studied. The results indicate that deposition rate and surface roughness of the coatings increase with increasing spark pulse energy. A splattered porous morphology was observed in the surface layer, and underneath this, a uniform superfine columnar gamma phase structure with a column width of about 0.6 mu m. When exposed at 1000 degrees C, theta-Al(2)O(3) formed rapidly in the early oxidation stage. After 100 h oxidation, a large amount of theta-Al(2)O(3) was still present, and a dense and adherent, thin alpha-Al(2)O(3) scale had formed beneath it. (C) 2009 Elsevier B.V. All rights reserved.
