    摘要:

    以新型定向凝固鈷基高溫合金ＤＺ４０Ｍ為基體，研究其低壓化學(xué)氣相沉積鋁化物涂層的循環(huán)氧化行為，發(fā)現(xiàn)該涂層具有較高的抗循環(huán)氧化性能，涂層與基體結(jié)合良好。涂層退化主要是由外表面氧化膜的愈合消耗Ａｌ源所造成，沉積滲劑中加入Ｔｉ可加速涂層的退化。

    Abstract:

    The cyclic oxidation behavior of aluminide coatings made by low pressure chemical vapor deposition on to a new Co base superalloy DZ40M has been investigated. It was found that these coatings bonded well to the matrix well. Coating degradation when it occurs is due primarily to a depleting Al source as the oxide scale on outer surface is heated during cyclic oxidation. This degradation will be accelerated if Ti is added to the aluminizing reagent during deposition.
