    "device_name": "Modumetal Nanolamination",
    "goal": "Increase the strength and corrosion resistance of steel and other metals by up to tenfold, enabling longer-lasting infrastructure and lighter vehicles.",
    "problem_addressed": "Limited strength and corrosion resistance of conventional steel leading to premature failure of bridges, oil-field equipment, and other structural components.",
    "concept_summary": "Modumetal uses a multi-ion electroplating bath combined with precise current-profile control to deposit nanometer-scale alternating layers of different metals, ceramics, or polymers. The resulting nanolaminated coating (functionally graded) can be up to a centimeter thick, dramatically improving strength, wear, corrosion, and high-temperature performance of the underlying metal.",
    "detailed_description": "The process is an advanced form of electroplating where a bath containing more than one metal ion is used. By varying the electrical current at precise moments, layers only several nanometers thick and of differing composition are deposited, creating a nanolaminated structure. The technology also incorporates electrophoretic deposition and a Layered Electrophoretic And Faradaic (LEAF) method to blend metal, ceramic, and polymer phases, enabling functionally graded coatings that stop crack propagation and provide corrosion barriers. Parts up to meters in length have been produced, and a coating up to 1 cm thick can be applied in a single step. The company claims the process cost is comparable to conventional treatments such as galvanization.",
