International Journal of Electrochemical Science, 2012 The isothermal oxidation behavior of a second generation Ni-base single crystal superalloy was investigated in air at 1000°C and 1100°C. The microstructures of the oxide morphology and the crosssection area of the specimens after oxidation were analyzed ...

Beneficial Effect of Pt and of Pre-Oxidation on the Oxidation Behaviour of an NiCoCrAlYTa Bond-Coating for Thermal Barrier Coating Systems [PDF]
, 2011 The oxidation behaviour of a thermal barrier coating (TBC) system is a major concern as the growth of the thermally grown oxide (TGO) layer on the bondcoating creates stresses that greatly favour the thermal barrier spallation.

Effect of modification by Pt and manufacturing processes on the microstructure of two NiCoCrAlYTa bond coatings intended for thermal barrier system applications [PDF]
, 2010 Few studies have already shown that Pt influences the diffusion of aluminium and therefore the microstructure of β-NiAl or γ-Ni/γ′-Ni3Al materials. Besides, several works have revealed that the addition of Pt to MCrAlY (M = Ni and/or Co) improves the ...

Slip analysis in a Ni-base superalloy [PDF]
Acta Materialia, 2005 A Ni-base superalloy single crystal with Gamma/Gamma' structure was tested at room temperature along the , and directions. Consistent with previously reported investigations, this alloy did not obey the Schmid law and the CRSS (critical resolved shear stress) was noticeably lower for the -oriented samples.
