[0026] Example 1:
[0027] 1): Surface pretreatment: 400-1200 for copper samples # After grinding the sandpaper step by step, put the sample in the acetone solution for ultrasonic assisted degreasing and cleaning for 3 minutes, then rinse with deionized water and blow dry for later use.
[0028] 2): Pretreatment of the deposition electrode surface: select pure Ni (purity greater than 99.9wt%, the same in the following examples) and pure Cr (purity greater than 99.9wt%, the same in the following examples) electrode rods (both diameters are 3mm) Put it in acetone solution for ultrasonic assisted degreasing and cleaning for 5 minutes, then rinse with deionized water and blow dry for later use.
[0029] 3): Coating preparation process: use the selected copper sample as the substrate material, as the cathode in the deposition process, connect the cathode of the power supply device, use the Ni rod as the deposition electrode, set the deposition process parameters, and the deposition voltag...
