“…According to some previous researches, erosion were complicatedly in uenced by many affecting factors, which can be classi ed into 3 categories, (i) particle properties such as hardness or particle shapes of impact particles (ii) impacting conditions such as impact velocity or impact angle, (iii) target material properties such as mechanical properties or microstructure of target material [1][2][3][4][5][6][7][8][9] . It is also reported that there are correspondent impact angle dependences for different kinds of iron and steel materials, the impact angle dependences usually vary according to hardness, particle diameters and shapes of impact [10][11][12][13] . In order to make it clear the impact dependence of ductile material, brittle material and spheroidal graphite cast iron, the erosion by repeated particles impact were simulated by means of single particle impact of 2D FEM models 14,15) .…”

The results showed that the impact angle dependence of erosion can be re ected using the sum of equivalent plastic strain on the impacted surface 10) . However, the 2D FEM is too dif cult to simulate impact particle with all kinds of shapes except axisymmetrical shapes, but 3D FEM has abilities to build impact particles with complex shapes so as to explain erosion mechanism through Von Mises stress veri cation.…”

Erosive wear (or erosion) is a phenomenon where the material surface is damaged and removed by the continuously impacting of particles. According to researches on erosion, three types of parameters affect erosion, namely, particle properties, impacting condition, and target material properties.This study investigated the impact angle dependence of erosion by 3D Finite-Element-Method (FEM).In the FEM analysis, the velocity of impact particles was set as 20 m/s and the analysis duration was 0.01 ms. The size of the target material was 10 × 10 × 10 mm. The parameters of the target materials were set same as spheroidal carbide cast iron (SCI) and spheroidal graphite cast iron (FCD). The impact particle was spherical shaped steel grits with a diameter of 700 μm. The impact angle was changed from 10 degree with a 10 degree interval, up to 90 degree. To verify the analytical results, single particle impact tests was conducted at the same time.The results showed no difference in the equivalent plastic strain and Von Mises stress for spheroidal carbide cast iron with increasing impact angle, respectively. Both the equivalent plastic strain and Von Mises stress of FCD were largest around 60 80 degree. In addition, both the experimental and analytical results of the materials showed the same tendency. Therefore, by focusing on the plastic deformation of the material surface, it is possible to verify impact angle of dependence by 3D FEM analysis. The results of analysis indicate that spherical carbides can restrain the plastic deformation of the eroded surface. [Fig. 1 3D model.

“…There are a number of reports concerning the effects of microstructural constituents on the erosion behavior of cast irons [1][2][3][4][5][6], of which some are designed to investigate the influence of graphite [7][8][9]. From these studies, free graphite is generally considered nothing more than a notch except one report [5], and can therefore reduce the effective area in rendering resistance to irons under the erosion stream [7,8].…”
