摘要： The present disclosure relates to a NiTi alloy surface cutting process and a roughness adjustment method. Aiming at defects of difficult machining and unsatisfactory machining performance of Ni—Ti alloys, the present disclosure provides a surface cutting process of a difficult-to-machine nickel-titanium alloy, in which firstly, the nickel-titanium alloy is transformed from a two-phase state to a single-phase state using its transformation characteristic, and electrochemical nickel removal treatment is carried out on a surface of the alloy in the single-phase state so as to obtain a porous surface layer, and then a surface material with the porous surface layer is cut. The method provided by the present disclosure can effectively reduce machining difficulty of alloy materials, and can also obtain alloy workpieces with adjustable roughness, which is of great significance for NiTi alloy machining.
