The possibility of analytical determination abrasive particle impact velocity with the surface of any synthetic polymeric material with shock-abrasive processing in a low-temperature cooling for maximum efficiency of the process, ceteris paribus. The dependences for the calculation of such initial axial velocity of the abrasive particles in which at any distance from the nozzle of the jet device for shock-abrasion provided by the minimum time between two successive blows particles, which carried out an intense loading of the material increases its depreciation per unit of time and providing maximum the performance of the process.

This paper examines the structure and properties of worn mid-motor blades on heavy-duty motor graders operating in Yakutia. The wear characteristics of mid-motor blades at low temperatures are revealed, and operational data are analyzed. The chemical composition, structure, and properties of motor grader blades from two different manufacturers were analyzed. The results showed that the working parts of heavy road construction equipment are characterized by the presence of a finely dispersed, needle-like structural component, which undergoes appropriate heat treatment.
