High Speed Laser Cladding Repair Process Development

This project seeks to expand upon the exploratory project, 18-02-RM-03 results to more fully vet the capabilities of HSLC and investigate additional additive repair applications that are challenging due to strength requirements, distortion requirements, and wear requirement. Limitations to the performance of the developed HSLC system will also be addressed, including design of a nozzle with HSLC in mind that incorporates additional cooling and improved powder focus. The technology solution that will be delivered at the end of the project is HSLC material system repair techniques, including a new powder nozzle design, and a general process guide to describe application of the repair methods. This project will reduce primary feedstock by 0.014 million metric tons (MMT) steel, 13.8 PJ energy reduction, 0.8 MMTCO2e. Assumptions based on preliminary results of 18-02-RM-03.
