Modumetal introduced its zinc-based alloy, NanoGalv, part of its new class of nanolaminated materials with broad application in structural parts, coatings and claddings, thermal barriers, and armor. NanoGalv outperforms conventional galvanization processes by more than seven times, reducing the need for replacement parts over the life of metal components and associated risk of wear and failure. “Nanolaminated materials” refers to a class of materials comprising nanometer-scale particles deposited in layers that vary in composition, phase, microstructure, or a combination thereof. To create nanolaminated coatings, zinc-based metallic alloys are applied electrochemically, at room temperature, to steel substrates to enhance corrosion resistance and base-material-mechanical properties. The unique metal attributes achieved by nanolamination not only impart improved performance characteristics but also overcome intrinsic-material-property tradeoffs (i.e., hardness and toughness, creep and fatigue, corrosion, and wear) that are typically encountered in homogeneous materials. By balancing the tradeoffs in conventional material performance, nanolaminated materials have the potential for broad application as surface coatings, claddings, bulk materials, or as near-net-shape parts. The deposition process can be controlled to produce nanoscale layers with unique interfacial properties resulting in enhanced corrosion-resistance, elastic-modulus, strength, hardness, and fracture-toughness combinations uniquely different from conventional material processing.
