Anti-Erosion Function in Animals and its Biomimetic Application

Material failure is usually caused by corrosion, wear and mechanical damage. According to previous researches, erosion wear holds about 8% of regular wear in industrial production. In the present work, a new approach, which adopted the idea of coupling bionics to improve erosion resistance of machine parts, was presented. Simulation by ANSYS/LS-DYNA finite element software was applied to predict the relative erosion severity, and experiment optimum design theory was employed to design experiment scheme. Silica sand of particle size 105 µm–830 µm was used as the erodent. The erosion tests were carried out to validate the simulation results obtained. It is shown that the simulation results are in agreement with those of the experiment. The morphologies of eroded surface were examined by scanning electron microscope, and the possible wear mechanism was discussed.
