Abstract

This study aims to numerically investigate the erosion response and underlying damage mechanisms of SKD11 tool steel under varying particle impact angles and velocities. The study utilizes the Single Particle Finite Element Analysis (FEA) method with a Cowper-Symonds Strain Rate Material Model. In this study, SiO₂ particles measuring 0.7 mm in diameter were selected as the erodent, while the target material, SKD11, was sized at 1x1x0,5 mm. The impact angle was varied at 30, 60, and 90 degrees, and the impact velocity was set at 25 and 50 m/s. The simulation results indicate that SKD11 exhibits the highest resistance to erosion at lower impact angles. Erosion severity increases markedly as the impact angle rises, reaching a maximum at 60°. Moreover, different impact angles lead to distinct erosion mechanisms on the material surface. Increasing the particle velocity further intensifies erosion, with material failure and removal observed at 50 m/s. These findings provide insight into the combined effects of impact angle and velocity on erosion behavior and contribute to improved prediction and design of erosion-resistant SKD11 components.
