Advanced Nanocrystalline Cobalt Alloys and Composites as Alternatives for Chromium and Nickel Plating in Repair Operations

reportActive / Technical Report | Accesssion Number: AD1135595 | Open PDF

Abstract:

Integran Technologies Inc., in collaboration with Cirrus Materials Science and Corrdesa, successfully completed SERDP Project WP-2609, in which a cost-effective nanostructured cobalt phosphorus (nCoP) composite alloy was successfully developed for the repair and refurbishment of damaged components for use within the US Department of Defense (DoD). Validation testing performed in the project demonstrated that the novel nanostructured composite coatings meet and/or exceed the properties and performance of electroplated nickel coatings and Electrolytic Hard Chrome (EHC) and can be successfully applied to steel and aluminum components.
