- Summary:
- A surface phenomenon associated with the localized excessive growth of phosphate crystals on electrogalvanized (EG) steel is investigated. The excessive phosphate growth (id est, "nubbing") is found to correspond to pitting of the EG zinc coating during the degreasing process. In an industry first, alkaline degreasers of varying type are studied using electrochemical analysis and a correlation is found between the EG steel pitting potential and nubbing severity of pre-treated EG steel. Electrochemical analysis of lab-prepared degreaser samples confirms that degreaser pH is primarily responsible for pitting severity. Pretreatment parameter changes are discussed as being able to prevent such a phenomenon
