Corrosion sensors and methods of their use for monitoring corrosion of a material of interest. The corrosion sensors are adapted to be placed in the environment containing the material of interest during the period when corrosion is taking place. The corrosion sensors include a power source, a visual indicator and an electrode contained on a support. Changes in the electrical resistance of the electrode facilitate a display on the visual indicator including changes in color or brightness. Some corrosion sensors have power sources activated by directing a light source or other electromagnetic radiation source at the corrosion sensor. Some corrosion sensors have visual indicators containing thermochromic or electrochromic materials that are responsive to changes in voltage drop or current flow across the visual indicator. Some corrosion sensors have tracking devices to provide tracking information about the corrosion sensor. Some corrosion sensors have proximity sensors to inhibit the display on the visual indicator when not in proximity of a trigger.

Visually indicating corrosion sensing

A package for facilitating the protection of metallic surfaces against corrosion and including a blend of corrosion inhibitor and surface-conditioning component such as a degreaser, descaler, and/or anti-static component in liquid state impregnated into a substrate such as a wipe for simultaneous and direct application to the surface of the article being protected. The corrosion inhibitor component is preferably an amine salt of carboxylic acid, triazole, an alkali metal salt of aldonic acid, or alkanolamine salts of fatty acids, an alkali metal or alkanolamine salt of aromatic sulfonic acid, or blends thereof. The substrate is preferably a wipe fabricated from a fabric such as soft cotton, but may also include other wipe materials such as woven or non-woven polyolefin fabric, or non-woven materials such as paper toweling.
