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.

A description of the equipment and possibilities of surface morphology analysis on a new profilometer model 130 with a Russian-made nanometer attachment has been given. The analysis of the fracture surface of car steering rod material is carried out by means of the developed methodology for studying the morphology of the breaks of a metal samples with a nanometer resolution. The nature of the fracture is determined as fragile mode I. A fracture core at the composite insert boundary in the steel material of the steering rod was revealed.
