The fine structure of coatings on the basis Ni-Al formed by the magnetron method

Phase composition, fine structure and surface morphology of intermetallic coatings are investigated by X-ray analysis and TEM. It is shown that Ni3Al is the main phase of the intermetallic coating for all the investigated samples. There is a NiAl phase in the samples of the first type. Three types o...

Zusammenfassung:Phase composition, fine structure and surface morphology of intermetallic coatings are investigated by X-ray analysis and TEM. It is shown that Ni3Al is the main phase of the intermetallic coating for all the investigated samples. There is a NiAl phase in the samples of the first type. Three types of grains, differing in size, are discovered in the structure of nanocrystalline coatings: dislocation free, dislocation, and fragmented. The internal stresses, obtained by TEM and X-ray analysis, have close values.
