Influence of heat treatment and anodizing on the corrosion behaviour of additive manufactured AlSi10Mg alloy
Additive manufacturing (AM) processes produce complex and multifunctional items by layering pre-alloyed powder. Among them, direct metal laser sintering (DMLS) process encourages creation of distinct microstructures and internal phase distributions. These microstructures possess substantial influence on corrosion performance and mechanisms of corrosion resistance-improving surface treatments, such as anodizing. Hence, this study emphasize on corrosion performance of anodized and unanodized heat-treated AlSi10Mg samples manufactured through DMLS method. As built AlSi10Mg samples were subjected to stress relieving and T6 heat-treatment. The heat-treated samples were further subjected to anodizing process in H2SO4 electrolyte solution. Microstructural characterization of unanodized and anodized heat-treated samples was performed through microscopy analysis. In addition, corrosion experiments were performed in 1 M H2SO4 solution on anodized and unanodized heat-treated samples to determine Ecorr, Icorr and corrosion rate values. The corroded samples are further characterized to understand different failure mechanisms.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
