Preliminary Proof-of-Concept Testing of Novel Antimicrobial Heat-Conducting "Metallic" Coatings Against Biofouling and Biocorrosion.

ABSTRACT: NiMo (nickel-molybdenum) and NiMo with embedded CeO₂ nanoparticles (NPs; 100 nm) were tested as antimicrobial coatings (~15 μm thickness) on titanium (Ti) surfaces using an electrochemical process for heat exchanger applications onboard marine vessels. Preliminary static biofouling and biocorrosion (also known as microbiologically influenced corrosion) assessments were carried out in glass bottles using pure-culture Desulfovibrio vulgaris, a sulfate-reducing bacterium (SRB), in deoxygenated ATCC 1249 medium at 37°C, and using an alga (Chlorella vulgaris) mixed with general heterotrophic bacteria (GHB) in enriched artificial seawater at 28°C. It was found that the coating containing NiMo/CeO₂ NPs were much more effective than NiMo in preventing SRB biofil
