Mechanical and High Temperature Oxidation Properties of Cold Sprayed CoNiCrAlY Coatings for Thermal Barrier Coating

High-temperature degradation of plasma sprayed thermal barrier coating systems

Thermal barrier coating systems (TBCs) are used in gas turbines to prevent high-temperature degradation of metallic materials in the combustor and turbine. One of the main concerns regarding TBCs is poor reliability, and accurate life prediction models are necessary in order to fully utilise the beneficial effects of TBCs. This research project aims at developing deeper understanding of the deg...

The Study of High Temperature Oxidation behavior of Different Microstructures of HVOF Thermally Sprayed Coatings

Improvement of thermally sprayed coating properties by microstructure modification has been considered as a significant solution. Therefore, in this research the effect of dissolved oxygen content and post heat treatment on the formation and distribution of secondary phase particles, particularly in nano-scale in the coatings during spraying and after that were studied. Ni-5 wt% Al powders were...
