The Effect of Technological Parameters on Intensity of Shot Peening Process of 51CrV4 Steel

In the paper the effect of selected technological parameters of shot peening on process intensity of 51CrV4 steel was presented. The experiments were conducted according to statistical 3-level completed plan PS/DC 32. Technological parameters were changed in the range: shot peening time t = 1-3 min and pressure p = 0.2-0.4 MPa. In the article the analysis of experiment reproducibility, impact parameters significance and adequacy of equation were done. As the result of investigations the adequate equation was obtained describing the effect of technological parameters. Significant influence on process intensity was found in case of pressure and interaction of both analyzed technological parameters. The biggest energy of stream shots was gained at the maximum pressure of 0.4 MPa and the shot peening time of 3 minutes. As the result of analysis according to design of experiment (DOE) the adequate equation describing the dependencies between technological parameters and process intensity was found.
