The Manufacturing Processes Engineering research group at the University of Cordoba has validated a new method for the removal of anti-adherent fluoropolymer coatings using a continuous-wave (CW) Nd:YAG laser. The research focused on the factors involved in the removal process of coatings made of fluorinated ethylene propylene (FEP) and polytetrafluoroethylene (PTFE). The researchers compared stripping processes for FEP and PTFE nonstick fluoropolymer coatings, analyzed the qualities of each coating and the coating’s degree of influence on the energy efficiency and rate of...Read full articleRelated content from Photonics MediaARTICLESHybrid Additive Manufacturing Process Improves CoatingsA team at the Fraunhofer Institute for Production Technology (IPT) has introduced an additive manufacturing (AM) process that combines wire-based and powder-based laser cladding.
