RELIEF OF A SURFACE, STRUCTURE AND PHASE CONSTITUTION OF A ZONE ELECTROEXPLOSIVE ALLOYING METALS
Methods scanning and transmission electron microscopy thin foils lead researches of a relief of a surface,a structure and structural-phase conditions of a zone electroexplosive aluminizing and borualuminizing iron,and also coppering and borocoppering iron and nickel.It is established that owing TO overheating and the subsequent boiling up melting on an external surface of a zone alloying are formed pores.Mechanical interaction with melting the condensed particles of a jet causes occurrence on a surface of sites with the advanced morphology of a relief.It is shown that the maintenance of alloying elements and the synthesized phases with depth decreases.At coppering it is expressed more strongly,than at aluminizing.At binary alloying the gradient of structural-phase conditions on depth is more,than at single-component alloying.Features of three characteristic layers are considered: Thin superficial layer of the synthesized phases with nanocrystalline or quasiamorphous structure,an intermediate layer with structure cellular crystallization and a frontier layer at the bottom of a zone alloying with a high degree of plastic deformation.In some cases on border with a basis the thin layer with nanocrystalline structure and a low degree alloying found out.
