Originální abstrakt

The samples in present study were prepared by air plasma spraying (APS) of CoNiCrAlY coatings onto the nickel-based superalloy INCONEL 713LC substrate surface. Immediately, after the spraying was onto the CoNiCrAlY coatings outer surface pressed an high purity aluminium sheet by means of uniaxial cold pressing techniue. After that the samples were annealed at the temperature of 650 C for different dwell-time in argon-flow atmosphere. The modified CoNiCrAlY coatings enriched by aluminium were produced. Moreover the voids, imperfectly melted powder particles, and oxide scale present in original plasma sprayed coating microstructure were eliminated. The scanning electron microscope (SEM) was used to record the modified coatings microstructure. Changes in chemical composition were studied by means of energy dispersive microanalysis (EDX).
