Effect of Oxidation and Mechanical Properties of Low Thermal Conductivity Material Coated

Published on Sep 28, 2020

In this study the mechanical properties of air plasma sprayed YSZ, AlCrO3+YSZ AlCrO3+50% YSZ thermal barrier coating (TBC) coatings were evaluated and also compared with each other. The synthesized AlCrO3 is blended to commercial YSZ on ratio of bare and 1:1wt, 1:2 wt, were coated on IN718. The thermal barrier coatings on IN718 material were characterized by mechanical properties and oxidation behaviour was studied. The AlCrO3 is added as binding element to YSZ to improve the mechanical properties of TBC. The results of mechanical properties and oxidation graph are incorporated in this report. This work clears new pathways to achieved without bond coat to good adhesive strength and resist thermal expansion for TBCs
