Abstract

This article investigated the corrosion failure of galvanized steel that had been exposed to a metalworking lube. The investigation included metallographic preparation (sectioning, mounting, and polishing), microstructural analysis, optical microscopy, zinc coating thickness measurements, fluid pH measurements, microbiological testing, and Fourier Transform InfraRed spectroscopy. The results from this investigation showed that the failure that occurred was due to microbial corrosion.
