Self‐crack healing ability and strength recovery in ytterbium disilicate/silicon carbide nanocomposites
Source abstract
Abstract
Abstract The SiO 2 volatility and SiC recession in hydrocarbon‐rich combustion atmosphere is the main problem of SiC‐reinforced ceramics when they are utilized as coating materials for gas turbine blades. The composite of Yb 2 Si 2 O 7 ‐Yb 2 SiO 5 /SiC is expected as a self‐crack healing material that can avoid this problem because the monosilicate can react with the SiO 2 glass to form disilicate and hence further reinforce the composite. In this study, the composites, fabricated with various morphology of SiC nanofillers, were precracked and then heat‐treated in an oxidizing environment to activate their crack healing behavior. The healing effect as a function of filler morphology and annealing time was investigated. Healing mechanism and future applications of these composites were also discussed.
