Abstract
The microstructure of NiAl coating formed by air plasma spraying of ball milled NiAl30 powder is studied in this paper. Numerous chemical and structural inhomogeneities were determined by light microscopy, microhardness measurements, SEM, TEM, and EDX analysis. The coating is formed by a mixture of phases including α-Al and γ-Ni based solid solutions, β-NiAl, martensitic NiAl, and γ'-Ni3Al intermetallic compounds. Amorphous, partially crystallized and crystallized fine grained Al2O3 oxides with spinel structure were also determined.

Key words
NiAl coating, air plasma spraying, microstructure, TEM studies, intermetallic phases
