In a method for preparing a gradient hardened titanium alloy. A steel momentum block and a cleaned titanium alloy plate are sequentially placed into a steel base with a through hole from bottom to top, a cross sectional size of the through hole is matched with cross sectional sizes of the steel momentum block and the titanium alloy plate, and a height of the through hole is matched with a total thickness of the steel momentum block and the titanium alloy plate. An explosive frame is fixed on a top edge of the steel base, a high explosion velocity explosive with an explosion velocity of 7000 m/s or more pressed into a plate-shaped structure is placed in the explosive frame, and detonation is caused at one end of a top surface of the explosive to perform impact treatment on the titanium alloy plate, thereby obtaining the gradient hardened titanium alloy.
