Wear resistance of the samples has been also tested on a friction machine. Microstructure of specimens made of X12M, R18, R6M5K5steel has been studied using optical and electron metallography. Samples after dynamic alloying have been subjected to diffusion nitriding. The study has used an explosive method for creation of a high-speed flow of SiC + Ni and Al2O3 particles. Therefore a task for studying an effect of high-speed particle flows on structure change in tool steels and improving their performance properties has been set in the paper.
The effect exerted by particles moving at very high speeds can have both negative (in spacecrafts) and positive character (dynamic processing of tool steels). The influence of high-speed particle fluxes on changes in the structure and properties of materials has been widely studied currently.
