- •
Cavitation erosion was investigated on Cu samples with a high speed submerged cavitating jet.
- •
Small-diameter (0.4–0.6 mm) water cutting nozzles were used.
- •
The erosion rate and weight loss were calculated after long term exposure (1800 s).
- •
Effect of the standoff distance, nozzle diameter and angle of attack were investigated.
- •
Maximum erosion rate in function of these parameters were determined.
- •
Microscopic analysis of the erosion damage is presented.
