Considerable work has been carried out on overlay bond coats in the past several decades
because of its excellent oxidation resistance and good adhesion between the top coat and …

MCrAlY bond coats with high oxidation resistance are essentially important for improving the
life-time of thermal barrier coatings (TBCs). In this study, highly oxidation resistant MCrAlY …

Long-life thermal barrier coatings for high-performance gas turbines require MCrAlY bond
coats with high oxidation resistance. In this study, the oxidation resistance of bond coats was …

The high-temperature corrosion behavior of NiMoCrW and CoNiCrAlY base coatings
produced by high velocity oxy-fuel technique (HVOF) has been analyzed in dry air …

CoNiCrAlY coatings were deposited on IN-738 LC substrates using HVOF technique. The
microstructure of these coatings is composed of a single γ phase. A two-step high vacuum …

In this paper, the microstructure evolution of two as-cast CoNiCrAl bond coat alloys after
various isothermal heat treatments were investigated. The CoNiCrAl bond coat alloys were …

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

This paper investigates the β-phase coarsening behaviour during isothermal heat treatment
of free-standing CoNiCrAlY (Co-31.7% Ni-20.8% Cr-8.1% Al-0.5% Y, all in wt%) coatings …

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 …
