Abstract
The work is devoted to the study of some aspects of the formation of metal-matrix composites with a chromium matrix and nanodiamond reinforcing particles and determination of their working temperature in the case where nanodiamond agglomerates are significantly crushed. Methods for producing composite materials with the chromium matrix and nanodiamond reinforcing particles have been developed. Thermal analysis of the samples of the obtained composites has been carried out using differential scanning calorimetry, and the phase composition of the material has been determined. Mechanical alloying has been used to form the composite material, which made it possible to significantly reduce the size of nanodiamond agglomerates. Reducing the size of carbon material particles to the nanolevel leads to a significant decrease in the temperature of the onset of chromium carbide synthesis, namely to 450–500°C.
期刊介绍：
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques publishes original articles on the topical problems of solid-state physics, materials science, experimental techniques, condensed media, nanostructures, surfaces of thin films, and phase boundaries: geometric and energetical structures of surfaces, the methods of computer simulations; physical and chemical properties and their changes upon radiation and other treatments; the methods of studies of films and surface layers of crystals (XRD, XPS, synchrotron radiation, neutron and electron diffraction, electron microscopic, scanning tunneling microscopic, atomic force microscopic studies, and other methods that provide data on the surfaces and thin films). Articles related to the methods and technics of structure studies are the focus of the journal. The journal accepts manuscripts of regular articles and reviews in English or Russian language from authors of all countries. All manuscripts are peer-reviewed.
