【Abstract】 Bionic coatings have wonderful mechanical properties, and are used in micro\|electronic\|mechanical systems (MEMS). The authors have studied the design process and performances of some bionic coatings in their mimicking of the bamboo structure and conch shell system. The mechanical properties of different integrated coatings and gradient coatings were analyzed, and the stress fields for different coating systems were obtained using a finite element method. The results of numerical calculation showed that the integrated coating structure has advantages over the gradient layer system; and that the surface friction has significant influence on the stress field for both integrated coatings and gradient coatings. The advantages of conch shell and trough shell were exploited to design the thin films for the MEMS units. The prospects of bionic coatings are discussed.更多还原
