Manganese-cobalt spinel coating as well as preparation method and application thereof
The invention relates to a manganese-cobalt spinel coating as well as a preparation method and application thereof, and belongs to the technical field of solid oxide fuel cell materials. The manganese-cobalt spinel coating disclosed by the invention is coated on a base body containing a Cr element, and comprises a binding layer on the base body and a structural layer on the binding layer, the binding layer is prepared from the following components: a manganese cobalt spinel material, MnCr2O4 and Cr2O3; the structural layer is made of a manganese-cobalt spinel material; the chemical formula of the manganese-cobalt spinel material is Mn < 1 + x > Co < 2-x > O < 4 >, xlt; 2. The manganese-cobalt spinel coating is prepared by adopting a laser cladding method, so that the phase change of manganese-cobalt spinel can be effectively avoided, and the conductivity of the manganese-cobalt spinel coating and the binding force of the manganese-cobalt spinel coating and a metal matrix are improved; and the diffusion of the Cr element can be effectively controlled, and the problem that the cathode and an electrolyte material are poisoned by the Cr element is avoided.
