Similarity Criteria for Dusting of Plastic Materials

We propose a system of similarity criteria and criteria formulas that have made it possible to generalize the available experimental data on the erosion of plastic materials (metals) by particles, impacting with them at a right angle, with a root-mean-square error of 30%. The experimental data analy...

Description
Summary:We propose a system of similarity criteria and criteria formulas that have made it possible to generalize the available experimental data on the erosion of plastic materials (metals) by particles, impacting with them at a right angle, with a root-mean-square error of 30%. The experimental data analyzed have been obtained under the following conditions: velocity of the particles, 10-300 m/sec; temperature of the obstacle, room temperature-0.8T^sub m^; ratio between the densities of the particle flux and the obstacle material, 0.3-3; diameter of the particles, 40-3000 μm. A formula for generalizing experimental data on the erosion of materials by particles incident on their surface at different angles has been obtained.[PUBLICATION ABSTRACT]
