Bionic coatings have wonderful mechanical properties, and are used in micro-electronic mechanical systems (MEMS) as a method to prolong their service lives. The authors studied the design process and performances of a kind of bionic coatings. The mechanical properties of different integrated coatings were analyzed with a finite element method. Two kinds of systems, i) with gradient coatings and ii) with integrated coatings, were studied. The results of stress distribution show that systems with the integrated coatings have more advantages over the gradient coating systems. And the effects of friction on subsurface stress field were also analyzed.
