Prospects of using metallic nanocoatings to improve the operational characteristics of welded joints
The potential of employing nanostructured metallic multilayer to increase the durability and extend the service life of welded joints of metal structures is analyzed. Using a nickel and copper-based multilayer nanocoating as an example, a notable increase in the durability of the welded joint of up to 300...600% is observed. Corrosion tests reveal that the use of nickel and copper nanostructured metallic multilayer leads to the localization of corrosion processes at the "base metal-nanocoating" boundary. Considering the significant improvement of fatigue characteristics of welded joints and lower corrosion rate compared to welds without lamination, Ni-Cu nanocoatings can be used on offshore structures, provided that the condition of the protective anti-corrosion coating is monitored to mitigate the risk of galvanic corrosion at the base metal-nanolamination boundary.
