High-temperature Oxidation Resistance of Al2O3-Au Laminated Composite Coating Prepared on TiAl-based Alloy

High-temperature Oxidation Resistance of Al2O3-Au Laminated Composite Coating Prepared on TiAl-based Alloy

Novel composite coatings consist of Al2O3 micro-layers alternating with Au nano-layers have been prepared on TiAl-based alloy by magnetron sputtering. The results of high-temperature cyclic oxidation test at 900 °C for 200 h revealed that the multi-sealed α-Al2O3 and Au layers effectively suppress t...
