Embodiment 1
[0083] This embodiment provides a preparation method of MAB phase ceramic-metal layered composite material, the preparation method comprising the following steps:
[0084] (1) Preparation of MAB phase slurry:
[0085] (a) Dissolving PMMA in anisole, stirring at 450r / min for 3h to clarification, obtaining an anisole solution of PMMA with a concentration of 12wt%;
[0086] (b) mixing the MoAlB powder with a particle diameter D50 of 12 μm and the anisole solution of PMMA obtained in step (a), stirring at 450 r / min for 3 h to disperse evenly, and obtaining a MAB phase slurry with a volume fraction of 15%;
[0087] (2) Spray the MAB phase slurry obtained in step (1) on the surface of aluminum foil with an average thickness of 18 μm, and the spray thickness is 10 μm;
[0088] (3) drying and solidifying the aluminum foil sprayed with the MAB phase slurry in step (2), and then laminating to obtain a laminated blank, the number of laminated layers is n≥2, and n is a positive integer; ...
