Abstract:

This investigation examines the analyses of solid particle erosion which have been formulated for both ductile and brittle materials. The solid particle erosion process can be described qualitatively for several materials from microscopic examinations of the eroded surfaces, however most of the available erosion analyses are based on material removal models which do not represent the physical processes of material removal as they are presently known. A number of published results have been generally accepted by the erosion community without proper scrutiny of the basis for the conclusions reached. Some of these inconsistencies are pointed out and the various analytical approaches used in describing solid particle erosion phenomena are summarized. The need for an adequately characterized solid particle erosion testing capability is indicated due to the range of test parameters which have been found recently to significantly influence the measured erosion rates. Meaningful advancement in the field is strongly dependent on the development of a reliable experimental data base and experimentation which isolates and clarifies a particular feature of the material removal process.
