The paper presents the preliminary research results that were aimed at working out a technology of the surface roughness reduction by means of plastic working methods. The intermetallic phase NiAl and Ni3Al coatings that were plasma sprayed on a flat bar made of non-alloy steel (C45) were chosen for the research. The coatings underwent plastic working with the use of press. Three specific loads were used: 500, 800, 1100 MPa. The treated coatings exhibited 70% lower surface roughness as compared to thermally sprayed layers. However, high values of relative strain of coatings ( = 0.21 – 0.62) were obtained. Plastic working resulted in the decrease of corrosive potential values and increase of corrosive current density.
