Embodiment 1
[0030] The Zn-Al-Ni anti-corrosion functional impregnation layer of the present embodiment is prepared by the following preparation process parameters and steps:
[0031] 1) Substrate treatment: Put the substrate into the ultrasonic cleaning device for cleaning for 20 minutes to remove the oil stain on the surface of the substrate. After the substrate is taken out and blown dry, the substrate is put into the shot blasting equipment, and the steel shot with a diameter of 0.2mm is used to The substrate is shot blasted for 10 minutes to remove the rust on the surface of the substrate;
[0032] 2) Infiltration agent configuration: According to the infiltration agent formula (100 parts in total): 35 parts of zinc powder (400 mesh), 15 parts of aluminum powder (325 mesh), 1 part of nickel powder (300 mesh), 0.5 part of rare earth (400 mesh) (Mass percentage is 30% La, 55% Ce and 15% Nb), Al 2 O 3 48.48 parts of powder (200 mesh) were respectively weighed and mixed evenly with a po...
