Enhanced high-temperature corrosion resistance of (Al2O3–Y2O3)/Pt micro-laminated coatings on 316L stainless steel alloy
Source abstract
Abstract
Abstract A 7-layer (Al2O3–Y2O3)/Pt micro-laminated coating was successfully prepared on 316L stainless steel alloy by magnetron sputtering. High-temperature cyclic oxidation and hot corrosion tests were adopted to investigate the high-temperature corrosion resistance of the coating. It is revealed that the (Al2O3–Y2O3)/Pt micro-laminated coating which effectively suppressed the inward diffusion of oxygen and corrosive fused salt to an extremely low level can significantly improve the high-temperature corrosion resistance of alloy substrate. The great mechanical properties of such coating were attributed to the brittle/ductile laminated composite structure by means of multilayer toughening and release mechanisms.
