Remelting of M-CrAlY Air Plasma Sprayed Coatings by Means of Aluminium Cold Rolling and Conventional Heat Treatment

Popis výsledku v původním jazyce

Air plasma spray technique was used to produce NiCrAlY and CoNiCrAlY coatings on the Inconel 713 LC substrate. A certain amount of imperfectly melted powder particles, voids and oxides was also present in plasma sprayed coating microstructure. The aluminium sheet of 99,999 purity was cladded by means of cold rolling onto the coating surface. After the cladding of aluminium was the samples annealed at the temperatures of 650, 660 and 700oC for different dwell time in argon atmosphere. It was found that the temperature significantly affects the aluminium, which enable to create the NiAl and NiAl phases within the original plasma sprayed coating region. Annealing time also affects remelting of the Inconel 713 LC substrate surface. The microstructure of coatings was recorded by scanning electron microscope. Coating thickness and amount of voids were measured by means of image analysis. The microstructure of coating was recored by scanning electron microscope. Coating thickness and amount o
