High-temperature oxidation and hot-corrosion behaviour of EB-PVD β-NiAlDy coatings

? Cr/Dy doped ?-NiAl coatings were produced by electron beam physical vapor deposition. ? The microstructures of the Cr/Dy doped ?-NiAl coatings were characterized. ? The effect mechanisms of Dy and Cr on the cyclic oxidation of the NiAl coatings were investigated. ?

High temperature corrosion behaviour of a gradient NiCoCrAlYSi coating II: Oxidation and hot corrosion

The high temperature oxidation and hot corrosion behaviour of a NiCoCrAlYSi coating and a gradient coating were investigated. The gradient coating showed better performance of re-healing alumina scale due to its possession of more ? phase as Al reservoir.

Effect of pre-oxidation on the hot corrosion of CoNiCrAlYRe alloy

? The preoxidized specimen produces a uniform and protective oxide scale with good adhesion in hot corrosion. ? The time of pre-oxidation is crucial for subsequent performance of alloy in corrosion. ? Sulfur penetrating to substrate is trapped by Ni5Y phase to form stable yttrium sulfide.

The structure and high temperature corrosion performance of medium-thickness aluminide coatings on nickel-based superalloy GTD-111

?The coating grows inwardly during slurry silicoaluminizing process. ?The presence of silicon in aluminide structure increased the oxidation resistance. ?No catastrophic failure observed for the Si?aluminide coating in the oxidation test. ?The Si?

Hot corrosion behaviour of Ni3Al in sulphate–chloride mixtures in the atmosphere

Hot corrosion of Ni3Al intermetallic compound in the presence of sulphate?chloride mixtures was studied. A comminuted Ni3Al mixed with NaCl?Na2SO4, NaCl?Li2SO4, LiCl?Na2SO4, LiCl?Li2SO4 additions was oxidized in the air up to 1000?
