In this research, the cavitation erosion and dry sliding wear behavior of X5CrNi18-10 austenitic stainless steel has been analyzed through many tests. Cavitation erosion tests have been made for 180 minutes for the two samples and then for an extended duration of 1800 minutes for the surface which exhibited the best behaviour. All this tests were made using a cavitation experimental stand with the following main parameters for the ultrasonic generator (frequency: 20 ±0.5 kHz and amplitude: 50 μm). Dry sliding wear test has been made using a tribometer with the parameters: applied force 10 N, line speed 15 cm/s and distance 750 m. The analysed X5CrNi18-10 austenitic stainless steel had showed very good cavitation erosion behaviour, but a low dry sliding wear resistance compared to other steels as can be seen in the obtained results presented as cumulative mass loss and cavitation erosion rate for the cavitation erosion tests and as coefficient of friction and wear rate for the dry sliding wear test.
