OPTIMIZATION OF ELECTRON-BEAM DEPOSITION OF YSZ COATINGS: THE EFFECT OF THE SUBSTRATE ROTATION SPEED
We present the results of depositing a ceramic layer of thermal barrier coatings, based on yttria-stabilized zirconia, in the forevacuum range of pressure on a sample imitating a hot path blade of a gas turbine engine. The changes in the morphology of the coating cross section are shown for a sample rotation speed of 0 to 20 rpm. As a result, the rotation speed was selected to ensure that the thickness nonuniformity did not exceed 10%.
