#$%^&*AU2020101306A420200813.pdf#####Abstract of Description This invention discloses a core-shell structure MAX@MOm/AOn composite electrical contact reinforced phase material and the method for preparing it; the described MAX@MOm/AOn composite electrical contact reinforced phase material has a core-shell structure, the core is made of MAX phase material, and the shell is made up of oxide particles MOm and AO, or composite oxide layer MOm/AOn corresponding to the MAX phase material of the core; this invention also discloses the Ag/MAX@MOm/AO composite electrical contact material prepared by the above MAX@MOm/AOn material and the method for preparing it. After the MAX@MOm/AO composite electrical contact reinforced phase material prepared by this invention is compounded with the Ag matrix, the three-dimensional MAX plays the role of supporting the entire composite block structure, and the oxide particles MOm and AO, or the composite oxide layer MOm/AOn limits the interface diffusion between the Ag and MAX, maintains the conductivity of the composite material, and resists arc impact and absorbs arc energy to delay arc erosion damage in the process of electrical contact service.Drawings of Description Figure 1 -Ace V Spot Maqn Dot WDa 10 pmn 20 0 kV 3 0 3000x FE 7 ?
