This discloses protection against crevice corrosion of titanium surfaces, such as cells, piping and equipment used in a chlor-alkali membrane process, by employing in the areas in which titanium is subject to crevice corrosion a coating or film cast from a "paint" dispersion containing a fluorocarbon binder material, e.g. perfluorosulfonic acid polymer, a platinum group metal oxide, e.g. ruthenium oxide, and optionally a valve metal oxide e.g. titanium oxide; and a carrier agent, e.g. ethanol and water mixture. |
