EROSION PREDICTION OF PURE METALS AND CARBON-STEELS

A survey of the existing erosion theories and their agreement with test results on erosion of pure meta s an carbon steels is presented. It was found that the best correlation can be achieved with the use of Beckmann and Gotzmann's erosion theory. The program for computing the crosion rate of metals is based on the modified Beckmann and Gotzmann model. The respective data bases for most common abrasives and steels have been prepared. This program allows the prediction of the erosion rate over the range of impact angles from 0-degrees to 90-degrees and impact speeds from 10 to 200 m s-1 with an overall accuracy of +/- 30% for annealed and heat treated carbon steels and +/- 50% for pure metals.
