Resumen:
In humid environments, the formation of biofilms and microfouling are
known to be the detrimental processes that first occur on stainless
steel surfaces. This is known as biofouling. Subsequently, the
conditions created by metabolites and the activity of organisms trigger
corrosion of the metal and accelerate corrosion locally, causing a
deterioration in, and alterations to, the performance of devices made of
stainless steel. The microorganisms which thus affect stainless steel
are mainly algae and bacteria. Within the macroorganisms that then
damage the steel, mollusks and crustaceans are the most commonly
observed. The aim of this review was to identify the mechanisms involved
in biofouling on stainless steel and to evaluate the research done on
preventing or mitigating this problem using nanotechnology in humid
environments in three areas of human activity: food manufacturing, the
implantation of medical devices, and infrastructure in marine settings.
Of these protective processes that modify the steel surfaces, three
approaches were examined: the use of inorganic nanoparticles; the use of
polymeric coatings; and, finally, the generation of nanotextures.
