(1) The iron-based metal sample is firstly grinded by using 180-mesh sand paper until the surface roughness Ra is less than 5 mu m, then is finely grinded by using 1000-mesh sand paper until the surface roughness Ra is less than 0.5 mu m, and is then placed in a condition of containing 50g/L, na of NaOH 2 CO 3 Ultrasonic treatment is carried out in 25g/L of composite solution at 60 ℃ for 30min, the composite solution is taken out and rinsed, then is placed in 3-5% dilute hydrochloric acid solution for washing for 25-40s until dense small bubbles just appear on the surface of a sample, and is taken out and rinsed cleanly;
(2) Adding 1-3mg of black phosphorus nano-sheets with the number of layers being less than 5 into 5mL of absolute ethyl alcohol, performing ultrasonic dispersion for 30min, and slowly dropwise adding into a coating solution at the stirring speed of 300rpm, wherein the coating solution comprises the following formula: 22-26g/L of nickel sulfate, 29-31g/L of sodium hypophosphite, 18-22g/L of sodium citrate, 9-11ml/L of lactic acid, 8-12g/L of ammonium acetate, 26-32mg/L of thiourea and 4-6mg/L of sodium dodecyl sulfate; adjusting the pH of the coating solution to 4.4-4.8, and the temperature of the coating solution is 84-86 ℃;
(3) Placing the sample subjected to surface activation in the step (1) into the coating solution prepared in the step (2), reacting for 70-90min at the stirring speed of 300rpm, taking out, rinsing, drying, placing into a tube furnace, introducing nitrogen for protection, heating to 350-450 ℃, preserving heat for 55-65min, and cooling with the furnace to obtain the product.
