Electrochemical antibacterial composite coatings Sn – Ni – TiO 2

A technological process has been developed for obtaining composite electrochemical coatings based on a tin-nickel alloy containing TiO2 nanoparticles with antibacterial properties.
Achieved effect:
Tin-nickel-titanium dioxide coatings have increased corrosion resistance (more than 200 hours in a salt spray chamber), microhardness, endurance, adhesion to a metal base, decorative appearance, high bactericidal activity (80-85%) with respect to test cultures at low exposure time. Maximum bactericidal activity is observed against St. Aureus bacteria (85%). With an increase in exposure time, the bactericidal activity of the coatings increases to 100%.
Application:
This coating can be used for surfaces in public places: handrails, handles, turnstiles, etc.; for medical supplies; for food industry equipment; as a functional soldering coating in the manufacture of printed circuit boards.
