A plasma-accelerated polymer projectile drives shock waves into metal surfaces to create deeper compressive residual stress at lower cost.
Shock-wave cavitation embeds nanoparticles on a diamond wheel to overcome the air barrier and improve grinding-zone lubrication and cooling.
A vibrating housing accelerates larger shots inside coil springs to raise internal compressive residual stress without excessive surface roughness.
Low-velocity solid medium cleans jet engines without surface damage, resolving the trade-off between cleaning effectiveness and component integrity.
