The present application relates to the technical field of electrodeposited chromium plating, in particular to a trivalent chromium plating layer with a pearl shell biomimetic structure and a preparation method thereof. By regulating the composition of plating solution and electrodeposition process, stable periodic concentration polarization is induced to form potential composition distribution along the thickness direction of amorphous precursor plating layer; after annealing at 350-450 DEG C for 0.5-1 h, the potential composition modulation is explicit and phase transition occurs, and the pearl shell biomimetic layered structure is constructed in situ. The plating layer presents a periodic and alternating arrangement of natural pearl shell "hard-soft" multilayer stacked biomimetic layered structure in microcosm, wherein the chromium layer is a metallic chromium crystalline layer with a thickness of 5-30 nm; the carbon / carbon-chromium mixture layer is amorphous or nanocrystalline with carbon enrichment and in-situ formed chromium carbide phase, with a thickness of 1-3 nm. The total thickness of the plating layer is 5-30 microns, and the number of layers reaches 300-1800 layers. The structure can hinder crack propagation and improve load transfer, so that the plating layer has high hardness and wear resistance. Moreover, the process is environmentally friendly and controllable, and is suitable for mechanical parts, molds and functional surface protection.
