| Abstract Scope |
This presentation reviews the development of the GVSC Military Standard (MILSTD) which defines the requirements for validation of material selection, qualification, and inspection of a metallic feedstock deposition on a metallic substrate, for components that will be repaired by Direct Energy Deposition (DED). This standard shall be applied, but is not limited, to: the validation of a deposited feedstock for remanufacturing damaged and/or dimensionally discrepant components, restoration of worn and/or corroded components, and coating of component surfaces for performance enhancement such as corrosion, wear, and thermal protection. This standard addresses system capabilities for validation. Testing methods that address the development of parameters when inputs are unknown and methods for validating deposition quality and properties are discussed. A discussion on how and why the U.S. Army is perusing AM, and how the U.S. Army is overcoming such issues of transferring a set of validated parameters from one DED system to another. |
