Abstract

Pt-modified aluminide coating has attracted great attention due to its advantage of the integrated property in resisting both high temperature oxidation and hot corrosion. By the presence of Pt, the spallation trend of the grown oxide scale and the detrimental effect of S can be restrained at a very low level. Besides, Pt could promote α-Al₂O₃ formation and stabilize β-NiAl phase. Thus Pt-modified aluminide (Pt-Al) coating has been widely used in some crucial applications requiring reliability and extended service life. There are mainly PtAl₂, β-(Ni, Pt)Al and γ/γ′-NiPtAl phases existing inside Pt-Al coating. In this work, a single phase PtAl₂ coating was prepared on a Ni-based K38G superalloy through pulse-electroplating of Pt and pack aluminization under stepped heating mode. At 1100 ℃ , the isothermal oxidation behavior of the single phase PtAl₂ coating was evaluated by thermogravimetric analysis (TGA). Cyclic oxidation test of the PtAl₂ coating was performed within a vertical muffle furnace at the same temperature. The results indicate that the singular PtAl₂ coating possesses quite good isothermal oxidation resistance. However, its resistance against cyclic oxidation is very poor. The cyclic stress induced by repeated heating and cooling has caused visible detachment of PtAl₂ coating layer, and the spallation of PtAl₂ in further would lead to a premature failure of the whole coating system. Partial spallation of PtAl₂ layer, including undesirable consumption of Al inside β-NiAl nearby the spallation acts the main reason responsible for the final failure. Accordingly, it is not appropriate to apply single phase PtAl₂ coating in the high temperature services involving stress and load. The degradation mechanism of the singular PtAl₂ coating is investigated by discussing the stress generated from cyclic heating and cooling.

Key words: Ni-based superalloy Pt-Al coating thermogravimetric analysis (TGA) isothermal oxidation cyclic oxidation
