Simultaneous damage tests of cavitation erosion and slurry wear were carried out for Stellite, SCMnH11,TiNi shape memory alloy, and SUS304. The volume loss rate of the simultaneous damage is higher than that of slurry wear without cavitation for SUS304. On the other hand, the volume loss rate of the simultaneous damage is lower for satellite and SCMnH11,thus deceleration phenomenon appears. The simultaneous damage has no effect for TiNi shape memory alloy which subject to phase transformation due to cavitation bubble collapse pressure. It was concluded that work hardening by cavitation bublle collapse pressures is responsible for the deceleration phenomenon by simultaneous damage.
