Abstract
The effect of the electron beam physical vapor deposition CoCrAlY and CoCrAlY/ZrO2 + 8wt.%Y2O3 coatings with different thickness of the cera mic layer on the life of the nickel base alloys were investigated. Coa tings with a ceramic layer improved the time to failure of the base al loy. The dependence of the stress-rupture properties of alloys with th ree layers of metal/ceramic coating on the thickness of the zirconia l ayer is expressed by the curve with the maximum corresponding to a 100 mu m thickness.
