A 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. According to the team, the hybrid process produces protective tool coatings that are more wear-resistant, resource-efficient, and cost-efficient than those produced via conventional laser cladding methods. The hybrid process is also more flexible than a purely wire-based approach to cladding.
Laser cladding produces 3D structures through laser metal deposition (LMD); during LMD, the surface of the workpiece is heated with a laser beam while a filler material in the form of powder or wire is fed into the melting pool area. When the filler melts, it builds a…READ MORE
