High-throughput laser cladding in action. This image show the output of a 4 kilowatt direct diode laser system (Coherent 4000L) applying a Tungsten Carbide blend on a seal area to provide a highly wear resistant surface. Image courtesy of F.W. Gartner Thermal Spray.
Laser Cladding technology allows for complete metallurgical bonding with minimal HAZ (heat affected zone) and dilution, along with a reduction in other undesirable side effects such as oxidation and decarburization.
