Results of X-Ray Studies of Electro Erosive Tungsten-Free Hard-Alloy Powder Material

The purpose of the work was to study the phase and elemental compositions of new tungsten-free hard-alloy powder materials produced by electro erosive dispersion in an oxygen-containing medium. To produce new tungsten-free hard-alloy powder materials, an experimental laboratory setup for electro erosive dispersion was used X-ray spectral microanalysis (elemental composition study) was carried out by means of a QUANTA 600 FEG scanning electron microscope with a built-in EDAX analyzer. X-ray diffraction analysis (the study of the phase composition) was carried out using a Rigaku Ultima IV X-ray diffractometer. The results of X-ray diffraction analysis and X-ray spectral microanalysis of the new electro erosive tungsten-free hard-alloy powder materials obtained in an oxygen-containing medium showed that the main elements are Ti, Ni, C, O, Mo, and the main phases are TiC, MoNi3, Ni2O3, Ni, and Mo.
