Abstract
High-intensity electron beam treatment of ZrO2 + (6 – 8) % Y2O3 coating surface synthesized on GH33 alloy by EB-PVD was done. It is shown that the electron-beam exposure leads to smoothing of the coating surface and formation of nanoscale structures conducive to multiple (more than one and a half times) increasing of modified layer microhardness.
