Mechanical Pretreatment of Surface of Aluminum Alloy D16-T by Shot Peening

The paper describes the influence of shot-peening onto aluminium alloy D16-T surface. There are estimates focusing into microgeometry of the shot peened surfaces, their roughness and a size of selected shot peened material - the corund Based on the results of measurements, the evaluation was oriented on the curve of roughness, functionality of the surface roughness R-a and the necessary quantity of shot peening material q(nR) of estimated material depending on the grain size d(z).
