polyhedral, whereas quartz sand was almost spherical (Figures 7(a)-(d)). After erosion, the abrasives were damaged, and all four abrasives had broken into abrasive particles of different sizes... carbide (33.5 mm and 15.15 mm3, respectively), and both the lowest for quartz sand (14.0 mm and 3.70 mm3, respectively), as shown in Table 5 and Figure 11. Erosion depth and volume increased......
of Ministry of Education (Jilin University), Changchun 130022, China)Abstract:A new approach which adopted the idea of coupling bionics to improve erosion resistance was presented, by taking the desert.... And contrast tests were carried out at the best and worst test points of erosion resistance for four samples. Contrast tests show that the erosion resistance trend occurs in such order with the best......

of nickel in the samples was replaced by manganese for economic reason. Erosion–corrosion tests were conducted under 2wt% sulfuric acid and 15wt% quartz sand. The results show that the matrix of cast...Erosion–corrosion behavior of austenitic cast iron in an acidic slurry mediumKe Yang1,Lan Sun2,Yu-zhen Liu2,Hong-yuan Fan21.
