Improved corrosion resistance properties of CSS-42 L alloy fabricated by strengthening grinding process
The present study focuses on the influence of the strengthening grinding process (SGP) on the corrosion resistance of CSS-42 L alloy. To this end, the surface and cross-sectional characteristics of samples before and after SGP treatment were examined. In this regard, the surface morphology, roughness, microstructure, and phase content were analyzed. The results demonstrate a dense surface layer and a high surface roughness in SGP-treated samples. Through electrochemical and salt spray tests, it is confirmed that SGP treatment for 3 and 6 min improves the corrosion resistance of samples. It was found that the highest corrosion resistance can be achieved after SGP treatment for 6 min. The enhanced corrosion resistance of the SGP-treated samples originates from the synergistic effects of various factors, including surface roughness, dislocation density, the presence of compressive residual stress, the precipitation of Cr-phases, and the deformation of a dense surface layer.
期刊介绍：
Journal of Engineering Research (JER) is a international, peer reviewed journal which publishes full length original research papers, reviews, case studies related to all areas of Engineering such as: Civil, Mechanical, Industrial, Electrical, Computer, Chemical, Petroleum, Aerospace, Architectural, Biomedical, Coastal, Environmental, Marine & Ocean, Metallurgical & Materials, software, Surveying, Systems and Manufacturing Engineering. In particular, JER focuses on innovative approaches and methods that contribute to solving the environmental and manufacturing problems, which exist primarily in the Arabian Gulf region and the Middle East countries. Kuwait University used to publish the Journal "Kuwait Journal of Science and Engineering" (ISSN: 1024-8684), which included Science and Engineering articles since 1974. In 2011 the decision was taken to split KJSE into two independent Journals - "Journal of Engineering Research "(JER) and "Kuwait Journal of Science" (KJS).
