OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 25 No. 4 2023 Finally, future work should be reasonably conducted together with finite element analysis on local level to explicitly study particle-particle and particle-surface interactions and consider material properties in details. Such studies will be needed also for the estimation of erosion resistance of different types of coatings. Conclusions The numerical study made it possible to determine that: 1. The described approach allows to obtain a good agreement with the qualitative experimental data expressed in erosion crater profile and quantitatively, compared by integral non-dimensional erosion rate values for the studied conditions. 2. The calculated erosion rate under high-speed normal particles impact weakly depends on the turbulence model choice, including GEKO and its parameters; 3. On the contrary, the calculated wear rate significantly depends on the empirical erosion model choice and its calibrating coefficients. 4. The erosion rate profile and integral erosion rate are highly affected by the particle shape. The growth of drag due to change of the particle shapes leads to erosion rate decrease. For the studied conditions, shape factor values of ≈ 0.25 give the best agreement with the experimental data qualitatively and quantitatively. References 1.
