Abstract

The influence of laser remelting on the structure and properties of Al₂O₃ - Ni and ZrO₂ - Ni oxide layers plasma sprayed upon the Ni-base alloys has been examined. It has been stated that in the process of laser remelting there is a disappearance of open and close porosity, glazing, and formation of differentiated layer structure from the sample surface to the place of fusion with the substrate. It causes the decrease in the oxide layer thickness and increase in its adherence to the substrate, and its high temperature corrosion resistance in sodium sulphate, especially after additional diffusion chromoaluminizing.
