A strongly localized interaction of microplasma discharges with samples of a nickel-chrome (Ni-Cr) alloy is experimentally studied. In a near-surface layer of the specimens, a remelted area is created, which is characterized by strongly modified physicochemical properties of the material. This modification of the near-surface layer of Ni-Cr samples significantly improves their adhesion with different materials (ceramics, plastics, etc.) when durable composite structures are created.
