Modification of galvanic coating "tin-bismuth" by carbon nanotubes to improve the corrosive resistance
It was registered that carbon nanotubes "Taunit" in the content of the "tin-bismuth" deposition alloy electrolyte on copper demonstrate the inhibiting effect, thus expanding the area of the passive state of copper, which leads to increase in the corrosion resistance effect of the coatings.
The obtained results revealed that the corrosion current in the presence of CNT in comparison with the coating obtained without the CNT additive drops by 99%, and the potential of the corrosion shifts into the positive area. At the concentration of 50 mg/l of the CNT "Taunit" in the electrolyte maximum values of corrosion resistance are achieved.
