Known methods for surface treatment such as sand blasting, shot peening do not provide the required quality. Size of abrasive particles during handling of these methods are within 0.3-3 mm, resulting in a surface roughness after processing produces no higher than 3.2 micrometers, there is hardening of the surface layers of the parts. Negative factors include the fact that the large particles clog the small surface defects and as a result their diagnosis became difficult. Traditional methods of surface preparation of blanks lately giving way to new treatment technologies. In particular, modern inkjet technology of surface treatment is using, which minimizes the use of chemicals. We propose to carry out surface treatment by wateqet treatment. Processing the workpiece surface is exposed directed jet of pulp (slurry) consisting of a mixture of abrasive particles and water accelerated by compressed air onto the surface. Destruction of contaminants under the action of the jet is substantially erosive process. Chip technology allows to clean the surface of the metal and nonmetal of organic and inorganic contaminants, to give the new surface adhesion properties, provide the required surface roughness, to improve the appearance of products, to create a surface layer of compressive stress, etc. The proposed technology is versatile, has technological flexibility, compatibility with the existing process. Experimental studies on the influence of the main technological factors during blasting of hot-rolled steel sheets (the air pressure in the nozzle, the air flow performance when blasting the surface) are performed, graphical functions of received processing results of the parameters of technological regimes are presented. As an abrasive pomegranate concentrate used. It was found that with increasing pressure and airflow performance of the cleaning process is growing.
