Effect of diffusion barrier on the high-temperature oxidation behavior of thermal barrier coatings

Microstructural characteristics and degradation mechanism of the NiCrAlY/CrN/DSM11 system during thermal exposure at 1100 °C

“…MCrAlY (M = Ni and/or Co) coatings, with good balance between oxidation-resistance, corrosion resistance and ductility, are widely utilized on blades and other high temperature components in gas turbine engines both as standalone coatings and as bond coats for thermal barrier coating systems (TBCs) [1][2][3]. During long-term service at high temperature atmosphere, the protection effect of MCrAlY coatings is impaired by elemental interdiffusion between the coatings and the substrate [4][5][6].…”

Thermal-shock resistance of LnMgAl11O19 (Ln=La, Nd, Sm, Gd) with magnetoplumbite structure

“…A major disadvantage of YSZ is the limited operation temperature (1200 • C) for long-term application. Below 1200 • C, one of important factors that influence the lifetime of the TBCs is the thermally grown oxide (TGO) formation at the bond coat-ceramic topcoat interface [2,10]. At higher temperatures, the non-transformable phase (t -phase) of YSZ transforms to the equilibrium tetragonal (t) and cubic (c) phases.…”

Influence of Metal-Layer Thickness on Annealing behaviors of a NiCoCrAl/YSZ Multiscalar Microlaminate produced by EB-PVD

“…Electron beam physical vapor deposition (EB-PVD) is usually used for fabricating coatings and films [7][8][9][10]. Furthermore, it is also an effective way to produce large-sized metal foils for various applications due to the high deposition rate [11,12].…”
