The "Nickel Molybdenum Hard Chrome Alternative" topic under AFWERX aims to advance an innovative solution for replacing hexavalent chromium use in aerospace applications, such as landing gear actuators. Hexavalent chromium is known for its adverse health and environmental impacts, and the Department of War (DoW) faces regulatory mandates to eliminate its usage. The U.S. Army is tasked with phasing out hexavalent chromium by 2030, and similar efforts are underway in Navy facilities with a target elimination date of 2039. The focus of this project is to develop and validate the Maxterial H-max nickel molybdenum plating chemistry as an alternative to traditional hard chrome plating. Initial Technology Readiness Level (TRL) at the project start is estimated to be TRL 4, indicative of technology validated in a lab environment. The anticipated target TRL at the completion of Phase II is TRL 7-8, demonstrating system prototype demonstration in an operational environment. Desired outcomes include the identification, development, and validation of a robust alternative plating process that meets performance criteria for fatigue resistance, durability, and corrosion resistance in aerospace components. Additionally, the solution should support DoW modernization priorities in advanced materials and manufacturing while complying with environmental regulations and enhancing operational readiness. The required efforts will be divided into specific phases: Phase I: This phase will conduct full-scale fatigue testing, performance evaluation, and validate the plating process under simulated operational conditions. Deliverables will include comprehensive performance reports, validation of scalability (installing a dem/val tank), and a transition plan detailing how the process will be integrated into existing manufacturing protocols. DAF - 18 The minimum deliverables for the project will include: Validated Maxterial H-max formulation Fatigue and performance test data Operational readiness assessment Compliance analysis with existing DoW policies Transition plan By end of topic D2P2 completion, the anticipated benefits are to provide the DoW with a viable, environmentally safe alternative to hard chrome plating used in the aerospace industry, significantly reducing health hazards, and ensuring compliance with future regulations while enhancing durability and performance of critical aerospace components.
