    Abstract

    Modeling of cumulative erosion-time curves by the transient response method is based on the response curve of first-order servo systems to a step input. According to this model, it is possible to accurately model erosion-time curves by means of three parameters: Maximal erosion level, MDEF (MDE denotes mean depth of erosion) (μm), time constant, τ (h), and time lag (h). This method is adequate for ranking of materials by their erosion resistance and ranking of erosion test methods by their intensity. These rankings are performed for five metallic reference materials and seven erosion test methods for 22 erosion tests.
