  W pracy przedstawiono ocenę odporności kawitacyjnej 17 materiałów. Do opisu odporności kawitacyjnej zaproponowano nowy wskaźnik liczbowy uwzględniający długość okresu inkubacji, maksymalną prędkość niszczenia oraz czas po którym wystąpi maksymalna prędkość niszczenia materiału. Zaproponowany wskaźnik porównano ze wskaźnikiem δcav, który reprezentuje całą krzywą erozji kawitacyjnej materiału.
