GRAPHALLOY(reg) graphite/metal alloy self-lubricating bushings and bearings work in hostile environments from cryogenic to 750F, even in solvents and acids, and solve difficult applications to extend machinery service life and lower maintenance costs in pumps, mixers, ovens and furnaces, dryers, and dampers. GRAPHALLOY materials do not melt on cold flow and provide a low coefficient of friction. The material is corrosion-resistant in most liquids including sulfuric acid and caustics, and does not gall when run with close tolerances against rotating metal elements.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
