Nano-Structured Composite Making on the Basis of Boron and Chromium Using Metallothermy Method

The paper presents results of the investigations in respect of nano-structured composite creation on the basis of boron and chromium using metallothermy method. Structure and phase and composition of powder media obtained from oxides with the help of metallothermy method have been studied. It is revealed that such media contain nano-stractured elements in their composition. It is shown that a thermo-diffusion treatment of products using nano-structured powder media in comparison with conventional ones increases their operational resistance by several fold.
