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 
D 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-0.8 
Tm ratio between the densities of the particle flux and 
the obstacle material, 0.3-3; diameter of the particles, 40-3000 
m. A formula for generalizing experimental data on the erosion 
of materials by particles incident on their surface at different angles 
has been obtained.
