NASA needs heaterless gearboxes to enable cold capable mechanisms for missions to icy bodies and extreme cold environments like Europa; missions like a Europa lander will not have solar panels or nuclear sources for power generation and will have to meet mission objectives on battery power.
The problem to be solved is to make metal alloys that combine the benefits of metals and ceramics into a single material, optimally suited for wear-resistant applications. Such an optimal material would (1) have a higher toughness than ceramics, (2) have higher wear-resistance than any metals (approaching ceramics), (3) have low processing temperatures so that net-shaped forming is possible, (4) be machinable, and (5) be robust to extreme environments.
BMG Gears project’s unique material solution is a metallic glass with mechanical properties very similar to ceramics; it is high in strength, wear resistant, and holds up to extreme temperatures. Bulk metallic glass is moldable for reduced component cost after the initial tooling investment, and existing industry infrastructure supports alloy and component supply change, providing another opportunity for cost savings as well as opportunities for partnering with industry.
