The invention belongs to the technical field of nano materials, and in particular relates to a method for preparing a calcium fluoride coating on the surface of titanium and alloy thereof. In the method, the nano calcium fluoride coating is directly generated in situ on the surface of the titanium or the titanium alloy by one step method in electrolyte containing calcium ions and fluorine ions through micro-arc oxidation. The nano calcium fluoride coating prepared by the method has the nano crystal structure, is closely combined with a matrix, has the phase mainly comprising calcium fluoride and titanium oxide, can induce fluorapatite to deposit on the surface thereof after the calcium fluoride coating is soaked in simulated body fluid for less than 14 days, has good bioactivity and can be applied to the fields such as biomedical materials and the like.
