Solid particle erosion on the material surfaces is a very common phenomenon in the industrial field, which greatly affects the efficiency, service life, and even poses a great threat to life safety. However, current research on erosion resistance is not only inefficient, but also limited to the improvement of hardness and toughness of materials. Inspired by typical scorpion (Parabuthus transvaalicus), biomimetic functional samples with exquisite anti-erosion structures were manufactured. Macroscopic morphology and structure of the biological prototype were analyzed and measured. According to above analysis, combined with response surface methodology, a set of biomimetic samples with different structural parameters were fabricated by using 3D printing technology. The anti-erosion performance of these biomimetic samples was investigated using a blasting jet machine. Based on the results of blasting jet test, as well as regression analysis and fitting, the optimal structural parameters were obtained. In addition to the static test conditions, the optimal biomimetic sample was also eroded in rotating condition and showed excellent erosion resistance property. The presence of bump and groove structures, on the one hand, reduced the eroded area of biomimetic sample surface. On the other hand, they made the airflow turbulent and consequently reduced the impact energy of solid particles, which significantly improved the erosion resistance of biomimetic materials. This study provides a new strategy to improve the service life of components easily affected by erosion in the aviation, energy and military fields.

材料表面的固体颗粒侵蚀是工业领域中非常普遍的现象，极大地影响效率，使用寿命，甚至对生命安全构成极大威胁。但是，目前对耐蚀性的研究不仅效率低下，而且还局限于提高材料的硬度和韧性。受典型蝎子（Parabuthus transvaalicus的启发），制造出具有精美抗腐蚀结构的仿生功能样品。分析并测量了生物学原型的宏观形态和结构。根据以上分析，结合响应面方法，通过3D打印技术制备了一组具有不同结构参数的仿生样品。使用喷砂机研究了这些仿生样品的抗腐蚀性能。根据喷砂试验的结果，以及回归分析和拟合，获得了最佳的结构参数。除静态测试条件外，最佳仿生样品在旋转条件下也被侵蚀，并表现出优异的耐腐蚀性能。一方面，凹凸结构的存在，减少了仿生样品表面的侵蚀区域。另一方面，它们使气流紊乱，从而降低了固体颗粒的冲击能，从而显着提高了仿生材料的耐腐蚀性。这项研究提供了一种新的策略，以改善容易受到航空，能源和军事领域侵蚀影响的组件的使用寿命。
