Embodiment 1
[0041] Electrodeposition preparation of iron-cobalt alloy soft magnetic thin film:
[0042] 1. Carry out mechanical pretreatment on the deposition matrix material: rough grinding with sandpaper to remove burrs, oxide layers, etc. on the surface of the sample, and reduce the surface roughness;
[0043] 2. Pre-treatment of the copper substrate sample:
[0044] Alkaline cleaning and pickling are carried out sequentially on the copper substrate samples. The components of the alkaline cleaning solution for degreasing and rust removal of the substrate are: sodium hydroxide 35g / L, sodium dihydrogen phosphate 8g / L; the temperature of the alkaline cleaning for degreasing and rust removal is controlled at 50°C, and the time is controlled at 8 minutes;
[0045] The sample is electropolished, and the formula of the solute in the electropolishing solution is: citric acid 20g / L, ammonium citrate 46g / L;
[0046] The process parameters of the electrolytic polishing are as follows: the elect...
