The preparation method for a nano composite coating having a shell-simulated multi-arch structure includes: constructing a discontinuous metal seed layer using a vacuum plating technology; and inducing the deposition of a continuous multi-arch structure layer utilizing the discontinuous metal seed layer, thereby realizing the controllable orientated growth of the nano composite coating having the shell-simulated multi-arch structure. The nano composite coating having the shell-simulated multi-arch structure is of a red abalone shell-simulated nacreous layer aragonite structure, meanwhile has high hardness and high temperature resistance, has excellent performances such as high breaking strength, low friction coefficient and corrosion and abrasion resistance in seawater under the condition of maintaining good breaking tenacity, is simple and controllable in preparation process and low in cost, has unlimited workpiece shapes, is easily produced on large scale, and has huge potential in the fields of new energy, efficiency power, ocean engineering, nuclear energy, and micro-electronic/optoelectronic devices.
