1. A NiTi alloy surface cutting process, comprising: treating a NiTi alloy at a martensitic transformation temperature to obtain a martensitic single-phase NiTi alloy; removing Ni from the martensitic single-phase NiTi alloy in an electrochemical manner with the martensitic single-phase NiTi alloy as a working electrode so as to obtain a porous surface layer; cleaning, with a distilled water, and placing the martensitic single-phase NiTi alloy having the porous surface layer at the room temperature to restore the martensitic single-phase NiTi alloy to a two-phase state, and then cutting surface material with the porous surface layer.
