Abstract
The microstructure and wear resistant performance of plasma-sprayed Al2O3-Y3Al5O12 (YAG) coating were investigated. As-sprayed Al2O3-YAG coating was chiefly composed of amorphous phase, which may reveal superplastic feature in supercooled liquid region (from 503.0 °C to 906.5 °C). The as-sprayed Al2O3-YAG coating exhibits fine plasticity and toughness under the following conditions: a load of 2000 N, a rotational speed of 500 rpm and worn surface temperature above 500 °C, which significantly contributes to relieve accumulated coating stress and maintain the coating integrity. Therefore, plasma-sprayed Al2O3-YAG coating possesses excellent wear resistance under severe conditions.
