Localized Galvanic Corrosion of Welded Aluminum Alloys and Al-Boron carbide Compsites Local galvanic corrosion cells created during welding or due to reinforcement of aluminum alloys using composite materials create powerful electrochemical cells that initiate pitting or intergranular corrosion that can lead to stress corrosion cracking. The projected studies will target two areas "the distinctive localized galvanic corrosion of welded aluminum alloys as well as new aluminum composites for nuclear applications".

焊接铝合金和al -硼碳化物复合材料的局部电偶腐蚀在焊接过程中或由于使用复合材料增强铝合金而产生的局部电偶腐蚀细胞会产生强大的电化学细胞，引发点蚀或晶间腐蚀，从而导致应力腐蚀开裂。预计的研究将针对两个领域：“焊接铝合金的独特局部电偶腐蚀以及用于核应用的新型铝复合材料”。
