Embodiment 1
[0031] The surface of the nickel-titanium alloy medical metal stent is coated with a magnetic nickel-cobalt-tungsten metal film loaded with fluorouracil drug. The operation steps are:
[0032] 1. Prepare a composite chemical plating solution, which is an aqueous solution, and the components and content contained therein are: nickel sulfate (NiSO 4 ·6H 2 O) 8.4g / l, cobalt sulfate (CoSO 4 ·6H 2 O) 28.1 / l, sodium tungstate (Na 2 WO 4 )4.6g / l, sodium hypophosphite (NaH 2 PO 2 ·H 2 O) 18.2g / l, sodium citrate (Na 3 C 6 h 5 o 2 ) 29.4g / l, ammonium sulfate ((NH 4 )2SO 4 ) 66g / l, fluorouracil (5-fluoro-2,4(1H,3H)-pyrimidinedione) 250mg / l, pH 8.98;
[0033] 2. Take a nickel-titanium alloy wire biliary medical metal stent with a diameter of 0.2 mm (Youyan Yijin New Materials Co., Ltd. φ10×70, 00-N01-21) as the base material, and carry out alkali treatment in sequence. Washing, pickling, sensitization, activation treatment;

Embodiment 2
[0039] The surface of the 316L stainless steel medical metal stent is coated with a magnetic nickel-cobalt-tungsten metal film loaded with methotrexate. The operation steps are:
[0040] 1. Prepare a composite electroplating solution, which is an aqueous solution, and the components and content contained therein are: nickel sulfate (NiSO 4 ·6H 2 O) 52.5g / l, cobalt sulfate (CoSO 4 ·6H 2 O) 42.1g / l, sodium tungstate (Na 2 WO 4 ) 13.1g / l, sodium hypophosphite (NaH 2 PO 2 ·H 2 O) 53.2g / l, boric acid (H 3 BO 3 ) 34.4g / l, methotrexate 100mg / l, pH 4.5;
[0041] 2. Take a pair of 316L stainless steel biliary medical metal stent (φ10×70) with a diameter of 0.2mm as the base material, and carry out alkali cleaning, pickling, sensitization and activation treatment in sequence;
[0042] 3. Place the composite plating solution prepared in step 1 in a temperature-controllable plating tank, and adjust the temperature of the composite plating solution in the plating tank to 30° C.; ...
