Summary:In accordance with one embodiment of the present disclosure, a method for preventing corrosion of a plasma-exposed yttria-coated constituent from ambient acidic hydrolysis wherein the plasma-exposed yttria-coated constituent includes a hydrolysable acid precursor is disclosed. The method may include: removing the plasma-exposed yttria-coated constituent from a semiconductor processing assembly; binding the plasma-exposed yttria-coated constituent with flexible moisture wicking material; hydrolyzing the hydrolysable acid precursor with an overwhelming aqueous admixture to form a vitiated acidic compound, wherein the flexible moisture wicking material pulls the vitiated acidic compound away from the plasma-exposed yttria-coated constituent with capillary action; dehydrating the plasma-exposed yttria-coated constituent with additional flexible moisture wicking material to pull a latent amount of the vitiated acidic compound away from the plasma-exposed yttria-coated constituent; and isolating the plasma-exposed yttria-coated constituent from ambient moisture in a moisture obstructing enclosure.
