Columns More âsmall thinkingâ with big paydays Willard C. (Bill) Capdevielle, P.E., Contributing Editor In my February 2021 column, I introduced a nanotech product called NanoGalv ® offered by Modumetal (www.modumetal.com). NanoGalv ® is being clad onto fasteners to give them strong anti-corrosive properties. This month, I want to cover a similar product offered by ModumetalâNanoPlex®. This product is very similar to NanoGalv ®, employing the same nano-laminated alloy structure, as shown in Fig. 2 in my February 2021 column. However, unlike the zinc-nickel alloy used in NanoGalv®, NanoPlex® is a cobalt-nickel nano-laminate alloy. NanoPlex ® enjoys superior corrosion resistance, as well as enhanced wear resistance in the harshest subsurface environments.
