An Improved Method for Determination of the Cavitation Erosion Resistance by a Weibull Distribution



The improved method for determination of cavitation erosion resistance is based on the erosion strength concept and the Weibull cumulative distribution function. Cavitation erosion resistance is the ratio between the erosion intensity, which is the external load, and the erosion rate, which is the response of the eroded material. The time at which this erosion rate is determined is t200, i.e., when the average eroded thickness reaches 200 µm. This time ensures that the cavitation erosion resistance of both the boundary layer and the base material can be determined. The improved method is simple, easy to apply, and overcomes the drawbacks of the normalized erosion method and the erosion strength method. In this case, cavitation erosion resistance is an independent, measurable value with units of stress.
