Abstract:
INTRODUCTION
Shot peening is achieved by directing a powerful shot stream
at components.The stream’s power depends upon the
velocity, flow rate and density of the shot and carrier fluid
(normally either air or water). Much of the power of the shot
stream is absorbed when it strikes a component causing dents,
compressive residual stress and surface work-hardening. The
force exerted on components is rarely considered – but is
very important. This force can easily be measured, giving an
insight into the relative contributions of shot and carrier fluid.
