Abstract

The studies of the surface relief, structure and phase composition of silumin surface layer modified by the electric explosion of the aluminium conductor with the weighed sample of yttrium oxide were done by the methods of modern physical material science (atomic-force and transmission electron microscopy) in the research. It is stated that the multi-layer structure which consist of the highly porous coating inhomogeneous in thickness, the liquid phase alloying layer and the thermal effect layer, is formed in the top layer. It is revealed that the top layer possesses a submicro- and nanodimentional multi-phase structure. The particles of silicon, Y 2 O 3 , YSi 2 and Y 2 Si 2 O 7 are the hardening phases of this structure. It consists of the cellular crystallization structure being characterized by the inhomogeneity in the distribution of the alloying elements.
