“…From the micrograph there is not apparent microcrack on the surface. That is because mild steel is a typical ductile material and is therefore eroded at a low impact angle, which has also been observed in the previous researches [9,10] .…”

A three levels orthogonal table-L 9 (3 4 ) was used, namely, impact angle, rotating speed, erodent size, and surface configuration were considered. The three bionic surface configurations are pit, groove, and ring. The experimental results indicate the experiment factors affecting erosive rate are, in their sequence of contribution, erodent size, impact angle, configuration, and rotating speed; the erosive rate increased with increase in rotating speed, erodent size; the erosion resistance of the sample with ring structure is higher than that of the other two samples. Based on this result, regression orthogonal experiment was carried out to select the optimal erosion resistance condition with respect to the ring bionic surface configuration. Regression equations between erosive rate and experimental factors of ring surface configurations were obtained.

“…General method to reduce erosion is to enhance the wearability of material surface by means of using wear resistant materials or coating material with better wearability, resulting in cost increase [7][8][9][10][11][12][13][14] .…”

“…There have been several attempts to correlate erosion resistance with various mechanical properties of polymers and composites [11][12][13][14][15][16][17][18][19]. The dependence of erosion rate up on mechanical properties is complicated because deformation caused by erosive particles is associated with high strain rates about 10 5 to 10 6 s −1 and the stress state is complex [13].…”

“…Composite materials are increasingly used in a wide variety of areas as alternatives to conventional polymers, metals, and alloys. Numerous parameters [1][2] including impingement velocity, impingement angle, type, size and shape of the eroded element, nozzle geometry, stand-off distance, temperature, dry and wet conditions, environment, roughness and hardness of the surface, and fiber orientation are related to erosive damage of the target surface. Repeated impact of materials under different test parameters cause material loss and reduce material life.…”

Abstract. Composite materials are used in a wide range of applications. The erosion properties of combination of glass, jute and carbon fiber-reinforced polyester were analyzed in this study. Randomly-shaped silica (SiO 2 ) particles of various sizes (300-355μm, 355-500μm, and 500-600μm) were selected as the erosive element. Impingement angles between 15-90°, impingement velocities between 30-50 m/sec, and stand-off distances of 15-25 mm at ambient temperature were selected. During experiment, the maximum erosion of the tested composite occurred at 60° impingement angle, indicating a semi-ductile nature of the test material. Erosion increased with impact velocity and decreased with stand-off distance. In a dimensional analysis, erosion efficiency (η) and the relationship between friction and erosion were established. Test results were evaluated using Taguchi"s concept to minimize the observations needed, and ANOVA was used to identify interactions between tested parameters and to identify the most significant parameters. The S/N ratio indicates that there is only percentage of deviation between the predicted and experimental results. In further, sophisticated analyses and GMDH methods were employed, and surface damage was examined using scanning electron microscopy (SEM) to examine the nature of the wear behaviour.
