中文摘要:
自然有机体拥有的某些特别函数被在他们的身体表面上在多重典型特征上面联合经常形成。在生物系统由联合现象启发了,有非光滑的机械性质和微结构特征的联合效果的中等碳钢标本被激光处理制作。有简历的标本的热疲劳行为模仿的联合表面被调查并且比较。结果证实了那模仿的方法有的如此的一份简历改进中等碳钢标本的热疲劳性质上的有益的效果。在简历后面的相关机制为解释提高的热疲劳抵抗的模仿的联合效果 preliminarily 被讨论。
英文摘要:
Some kinds of particular functions possessed by natural organisms are often formed by coupling up the multiple typical features on their body surfaces. Inspired by the coupling phenomenon in biological system, the medium carbon steel specimens with the coupling effect of non-smooth mechanical prop- erty and microstructural features were fabricated by laser processing. Thermal fatigue behavior of specimens with biomimetic coupling surface was investigated and compared. The results confirmed that such a biomimetic method has the beneficial effect on improving the thermal fatigue property of medium carbon steel specimens. The related mechanisms behind the biomimetic coupling effect for explaining the enhanced thermal fatigue resistance were discussed preliminarily.
