Study of two-layer composition zirconium dioxide-nichrome plasma coatings
The subject of this paper is the study results of the plasma jet parameters and the fractional composition of the initial powder influence on the characteristics of the two-layer composition coatings of the shielding elements, based on nickel-chromium and zirconium dioxide. Optimization based on obtaining the maximum rate of use of the powder (CIP) is carried out. The microstructure investigation results of of the cross sections of coatings obtained are performed using scanning electron microscopy. The cross sections microstructure of ZrO2 coating and intermediate Ni-Cr layer is examined.
