AETC has experience and industrial expertise in addressing various aspects of ultra-high temperature tribological applications where the movement of an object defined as armatures is induced by the Lorentz Force. In catering to this exciting technology of the future, we have developed durable high-temperature coatings on the exterior of armatures, modified the construction of rails, and coated the legacy copper rails with electrically conductive graphite coatings with glass-like binders, to enable armature launch durability and reliable non-stick properties for fast forming molten metal. The things which we have learned from this application are increasingly useful in our work with automotive brake producers. Our technological solutions are solving some of the most difficult tribological challenges of mobile applications.
In 2010-11, American Energy Technologies Co. and its partners from Georgia Institute of technology (Atlanta, GA) took part in a cutting edge R&D effort, which was aimed at solving the short-term issues of high wear of rails in the US NAVY’s electromagnetic rail gun launchers. The wear is due to strong electromagnetic forces that erode copper rails at high temperatures, and as a result of high velocity-induced friction.
We developed a unique, thermally and electrically conductive coating with ceramic-like properties. The latter was applied onto copper rails and on EMRG armatures used by this technology platform. AETC dispersions effectively fought the meltdown of aluminum and prevented damage to copper rails, as well as the thermo-chemical oxidation of Copper as a result of reaction with high temperature gas being formed during the armature launch.
AETC’s lubricating, thermally stable and electrically conductive coatings were successfully evaluated by the EMRG technology platform.
