The invention belongs to the field of surface engineering technology and biological materials and particularly provides a nickel-titanium alloy support surface treatment method. The nickel-titanium alloy support surface treatment method is characterized by comprising the following steps that (1), a nickel-titanium alloy support is firstly polished using waterproof abrasive paper to remove a surface initial rough state, and then the nickel-titanium alloy support is cleaned in acetone and deionized water and dried by blowing to obtain a bright surface; (2), an anode oxidation technology is adopted to remove nickel in nickel-titanium alloy; and (3), a magnetron sputtering method is adopted, an auxiliary function of an electroacoustic energy conversion device is utilized, and a titanium nitride thin film layer is formed on the surface of the nickel-titanium alloy support by magnetron sputtering. The nickel-titanium alloy support surface treatment method has the beneficial effect that by means of intermittent sound wave control, the adhesion of surface layers attached to metal wires is effectively enhanced.
