Formation of Hypereutectic Aluminium-based Alloys or Nickel Aluminides Using Sacrificial Nickel Coatings

Popis výsledku v původním jazyce

The contribution is focused on hypereutectic alloys or nickel aluminides formation, where was utilized the unconventional method consisted of (i) sacrificial coating deposition onto the substrate and (ii) subsequent heat treatment. The 99.7 wt.% Ni powder was used to produce the nickel coating, by means of high velocity oxyfuel spraying, onto the 99.999 wt.% Al sheet surfaces. Then the as-sprayed samples were heat treated up to the temperatures of 700, 900 and 1200oC. The heating/cooling rate of the samples of 5oC / min was set up. The hypereutectic alloys or nickel aluminides formation was investigated by using differential thermal analysis, metallography and scanning electron microscopy. To estimate the chemical composition of phases the energy dispersive microanalysis was used. The resulting microstructure of Al-Ni hypereutectic alloys originated up to the temperature of 900oC is of aluminium matrix and Al3Ni eutectic. Instead of that, the nickel aluminides were produced at the temp
