Abstract

Laser cleaning technology is a promising technology for selective removal of coatings from substrates to facilitate re-use and recoating. A leading coating of interest for reduced friction and operating forces is Diamond like Carbon (DLC) coating. This paper reports on the energy requirements and associated unit process scope 2 emissions for the DLC laser removal process to facilitate re-use of tooling in a circular economy. This work can assist in providing a greater understanding of the energy requirements and of energy consumption and emissions reduction strategies for the DLC removal process. This is important for the transition to net-zero emissions in manufacturing.
