Currently, the service temperature of the MCrAlX coating (M= Ni, Co, or NiCo; X= minor
elements such as Y, Ce, Si, Ta) either as an overlay or as a bondcoat in some critical …

The present work is undertaken to determine the ability of the small punch test to determine
mechanical properties of CoNiCrAlY, a two phase bond-coat material found in thermal …

In this paper, the microstructure and thermophysical properties of two CoNiCrAl bond coat
alloys with differing Al contents were investigated. Two CoNiCrAl alloys with compositions of …

This paper studied the effects of internal oxide contents on the high temperature oxidation
and β-phase depletion behaviour of high velocity oxygen fuel (HVOF) thermally sprayed …

The β-phase depletion kinetics in MCrAlY coating alloys at different Al contents has been
investigated by diffusion simulations and comparing with available experimental data. The …

This paper investigates the microstructural evolution and fracture mechanism of the P91
steel during small punch tensile tests. Disc specimens, 8 mm in diameter and 0.5 mm in …

This paper details an investigation of the effects of oxide stringers on the β-phase depletion
behaviour in thermally sprayed CoNiCrAlY coatings. Vacuum Plasma Sprayed (VPS) …

Un-melted particles in thermally sprayed coatings are usually classified as impurity
elements. Such impurities have a strong influence on the coating behaviour due to their …

This paper investigates the high temperature oxidation behaviour of combustion flame
sprayed CoNiCrAlY coatings. Three CoNiCrAlY coatings with different fractions of internal …

Small punch tensile (SPT) tests have been carried out for a CoNiCrAlY coating at room
temperature (RT), 500° C and 700° C. Highly re-producible results have been obtained for …
