〈div〉〈p〉In this work, an enhanced room-temperature plasticity was achieved in a Zr〈sub〉62.8〈/sub〉Cu〈sub〉15〈/sub〉Co〈sub〉9.2〈/sub〉Ti〈sub〉6〈/sub〉Al〈sub〉7〈/sub〉 glassy alloy through the application of micro-arc oxidation (MAO) treatment. After treated for 15 and 30 min, the glassy alloy specimen exhibited an enhanced plastic strain of 5.5% and 7.9%, respectively. Both the introduction of nucleation sites for shear band at the coating/substrate interface owing to stress concentration and the physical constraint effect for the propagating shear bands from the in-situ formed coating are responsible for the enhanced plasticity. This finding may open a new avenue for developing ductile metallic glasses from a surface modification aspect.〈/p〉〈/div〉
