| 英文摘要 | Fe-based amorphous coating attracted great interest in a novel thermal barrier application for the design of advanced vehicle engines, especially when modified by ceramic addition. In this work, we focused on the ceramic content of a previously developed FeCrNbBSi/YSZ composite coating to tailor the thermal insulation and mechanical properties. The composite coatings synthesized by atmospheric plasma spraying (APS) comprise of well-formed amorphous matrix and dispersed YSZ splats. A nanoscale and amorphous interfacial layer forms between the metallic and ceramic splats due to the separate melt and rapid solidification of sprayed particles. Increasing YSZ additions significantly improve the thermal insulation ability of the composite coatings, granting the FN-30Y (FeCrNbBSi-30%YSZ) coating an extremely low thermal conductivity of 2.72 W/(m center dot K) at 600 degrees C, whose underlining mechanism is revealed as the suppression of electron thermal conductivity and the contribution of interfacial thermal resistance. Benefited from the formation of nanoscale interfacial layer to alleviate interfacial flaws, the moderate YSZ additions only induce a limited sacrifice of the fracture toughness, rendering the FN-20Y (FeCrNbBSi-20%YSZ) coating to maintain a high value of 3.40 MPa center dot m1/2, but excessive additions dramatically hamper the mechanical property of composite coating. The present results emphasize the importance of establishing balanced properties of Fe-based amorphous composite coating for thermal barrier application and provide an inspiration for future works aiming to tailor the performance of extensive metal-matrix composite coatings. |
