A New Configuration for Coaxial Energetic Deposition
As part of a DOE funded small business innovative research (SBIR) grant, AASC has developed a new configuration for coaxial energetic deposition coatings called Hollow External Cathode Coaxial Energetic Deposition or HEC-CED.
An article titled "New configuration for efficient and durable copper coating on the outer surface of a tube" was published in Physical Review Accelerators and Beams that details the technique using cathodic arcs generated on the inner surface of a large cylindrical cathode to coat the outside of a stainless steel cylinder with a well adhered copper film. Tests showed the HEC-CED process produced a film with superior adhesion over films deposited using electroplating.
The process can be tailored to coat any irregular cylindrical substrate and can be used to deposit any metal film including niobium to produce superconducting hardware. Please read our article for additional information about this exciting development.
