Surface Topography of Chromium Coatings after Pneumatic Ball Peening

Abstract:

The paper presents the results of measurements of surface topographies of chromium coatings after pneumatic ball peening. The studies were conducted on steel samples. Four pneumatic ball peening parameters were changed: ball diameter, shot peening pressure, distance between nozzle and workpiece and time of machining. The changes of 3D surface parameters were analysed. The correlation analysis was applied in order to obtain minimum number of parameters describing shot peened surface. Connection between fatigue strength and selected surface topography parameters was investigated.
