摘要
A new coating with Er2SiO5 as inner layer and LaMgAl11O19 (LMA) as top layer was designed and deposited on C/SiC composites by atmospheric plasma spraying to improve the oxidation resistance of the substrate at high temperature. Microstructure, oxidation protection and failure mechanism of the Er2SiO5/LMA coating during dynamic thermal cycling (DTC) were investigated. The results showed that a good interfacial bonding between the substrate and the coating was present before and after DTC test. Weight loss for the sample coated on one-side was 4.5% after 11 cycles of heating for 85 min, and for the uncoated sample was as high as 20.6%. Failure mechanism of the coating resulted from the liquid sintering of the coating and the formation of bubbles between the substrate and the coating. (c) 2013 Elsevier B.V. All rights reserved.
