摘要： A method of forming an oxide coating for reducing the accumulation of radioactive species on a metallic surface exposed to fluids containing charged particles is disclosed. The method includes preparing an aqueous colloidal suspension containing about 0.5 to about 35 weight percent of nanoparticles that contain at least one of titania and zirconia, and about 0.1% to about 10% 2-[2-(2-methoxyethoxy)ethoxy]acetic acid (C7H14O5) or polyfluorosufonic acid in water, depositing the aqueous colloidal suspension on the metallic surface, drying the aqueous colloidal suspension to form a green coating, and then heating the green coating to a temperature of up to 500° C. to densify the green coating to form an oxide coating having a zeta potential less than or equal to the electrical polarity of the charged particles so as to minimize deposition of the charged particles on the metallic surface. The nanoparticles have a diameter of up to about 200 nanometers.
