LASER CLADDING WITH COBALT-BASED HARDFACING ALLOYSA. FRENK and J.-D. WAGNIÈRE
Centre de Traitement des Matériaux par Laser, Ecole Polytechnique Fédérale de Lausanne, CH-1015 Lausanne, Switzerland
Preliminary results aimed at designing Co-based hardfacing alloys specifically for the laser cladding process are reported. Three alloys, ranging from hypo- to hypereutectic were deposited using scanning velocities between 1.7 and 170 mm/s. The microstructures and the dry sliding wear resistances of the clads were investigated. First trends relating composition to dry sliding wear resistance were deduced.
