| 英文摘要 | Absorbing materials have gained great applications for the capability of electromagnetic (EM) reflection reduction. So far, it is still very challenging to simultaneously achieve high-temperature resistance and broad working band in one design. This work reports a composite coating to realize this goal by using refractory Al2O3 coating and high-temperature conductive FeCrAl by atmospheric plasma spraying (APS). The reflection reduction mechanism is the phase cancellation instead of absorption. By spraying the FeCrAl structure on the surface of Al2O3 coating, it can behave as resonators to produce a phase difference. Here, with a thin thickness of 1.7 mm, the composite coating shows stable wideband EM reflection reduction from room temperature up to 700 degrees C, which originates from the excellent conductivity of FeCrAl and the steady dielectric property of Al2O3. In addition, a protective layer is employed to isolate the contact between the structural layer and the outside high-temperature environment, which prevents the conductive structure from corrosion and greatly enhances the practicability and feasibility for daily maintaining. Sample characterizations show that these layers are prepared of low porosity and closely bonded to form the composite coating. The EDX mapping scan results and micro-structure analysis demonstrate that the composite coating can exhibit excellent stability at high temperatures. Meanwhile, XRD results at different temperatures indicate the phase structure of Al2O3 coating is not damaged. This study provides a route to achieve temperature insensitive EM reflection reduction over a wide frequency range and enlighten a promising future of this material system. |
