Honeybee Robotics, a New York-based spacecraft technology and robotics company, selected Solar Atmospheres to provide heat treatment for drivetrain components for its robotic explorer, which will perform drilling and sampling operations on Venus. The components are comprised of a specialized alloy, Ferrium C61. The alloy is designed as a high-strength, high fracture toughness carburizing-grade steel capable of high-temperature applications in corrosive environments. Solar Atmospheres developed the processing conditions required to optimize the properties for the specialty alloy. The drivetrain components are vacuum carburized at 1825°F, high-pressure nitrogen gas quenched, frozen at -150°F and tempered in a vacuum at 900°F.
