1. A method of treating or maintaining an apparatus, the method comprising:
subjecting at least one treated component of an apparatus to electrochemical corrosion protection, the at least one treated component having surfaces treated with a coating of a treatment composition of a colloidal particle dispersion having inorganic nanoparticles with an average particle size from 500 nm or less that exhibit properties of Brownian motion, at least some of the inorganic nanoparticles being ionically charged nanoparticles, and wherein at least some of the ionically charged nanoparticles reside on the surfaces when the at least one treated component of the apparatus is subjected to the electrochemical corrosion protection.
