Reduction of particle embedding in solid particle erosion of polymers

► Embedded Al2O3 particles after AJM on ABS, PTFE, PDMS and PMMA were quantified. ► Methods to reduce particle embedding were investigated. ► Cryogenic AJM greatly reduced embedding of Al2O3 particles in ABS, PTFE and PDMS. ► The best method for reduction was by freezing after blasting with glass beads.
