Abstract

The present study aims at a detailed evaluation of mechanical, tribological, and high temperature oxidation resistance (at 1000 °C under isothermal condition) properties of YSZ, and Al2O3 based thin films developed by pulsed laser deposition technique. The mechanical and tribological properties of YSZ and Al2O3 thin films showed significant improvement with increasing the deposition temperature during pulsed laser deposition process. The kinetics of oxidation was reduced due to pulsed laser deposition and Al2O3 coating offered a superior oxidation resistance property as compared to YSZ coating. However, the deposition temperature has no significant effect in reducing the TGO growth rate of the pulsed laser deposited thin films.<br/><br/>Publisher Statement: NOTICE: this is the author’s version of a work that was accepted for publication in Ceramics International.
