This application relates to a wire rod, an arc-sprayed wire, and a preparation method thereof, belonging to the technical field of arc-sprayed materials. The chemical composition of the wire rod, by mass fraction, is: C: 0.08%~0.14%, Si: 0.10%~0.60%, Mn: 1.50%~2.00%, P≤0.020%, S≤0.020%, Cr≤0.10%, Ni≤0.10%, Mo≤0.05%, Cu≤0.10%, Ti≤0.010%, Al≤0.020%, N≤0.010%, TO≤0.010%, with the remainder being Fe and unavoidable impurities. The wire is prepared by optimizing the chemical composition of the alloy wire rod through processes such as smelting, continuous casting, rolling, surface treatment, rough drawing, copper plating, and fine drawing. The mass fraction of Cu is 0.10%~0.25%, and the other elements are the same as those in the wire rod. This wire material has excellent wear and corrosion resistance and adhesion strength to the aluminum alloy substrate. It can form a stable protective coating on the inner wall of the engine cylinder, taking into account both the advantages of engine lightweighting and high performance requirements, and effectively supporting long-term service.
