This study is devoted to investigation the
influence of technological parameters of impulse shot peening,
impact energy E, ball diameter d and distance between dimples
x on the geometric structure of the surface of objects made of
titanium alloy Ti6Al4V. It was found that impulse shot peening
changed the topography of the surface after milling. For most
impulse shot peening conditions, there was an increase in the
surface roughness parameters Sa, Sz, Sp and Sv, the exception
being the use of a ball with d = 12.45 mm for impulse shot
peening. For all analyzed conditions, the surface material ratio
Smr was higher after impulse shot peening than after milling (it
increased by approx. 3 times to approx. 600 times), which most
likely means increased abrasive wear resistance. The waviness
parameter Wz was lower after impulse shot peening than after
milling (Wz decreased from 10% to 90%)
