A Study on the Occurrence of Discouloration / Blackening / Dezincification / Corrosion on 7.62 mm Ball Ammunition Manufactured by Ordnance Factory Varangaon
Year: 2025
Type: article
Abstract: : This study examines the persistent degradation of 7.62 mm ball ammunition from Ordnance Factory Varangaon (OFV), characterized by unwanted changes in appearance and structural integrity. Using a combined analytical and qualitative approach, the research assesses the success of modified protective treatments, the role of sulfur-based contaminants, and the effects of storage and packaging. Key results demonstrate that sulfur, originating from packaging and wax, is a significant cause of surface blackening. Furthermore, while the new protective coating process requires thorough confirmation, relying solely on immersion cleaning proves insufficient for preventing recurring corrosion. The research concludes by suggesting ways to refine the protective coating process, investigate new cleaning techniques, and establish a system of continuous assessment to enhance product quality and user satisfaction. This research provides insights into quality management within ammunition manufacturing, emphasizing the need for robust evaluation, process verification, and innovative approaches to solve longstanding corrosion and degradation problems.
