Title: LASER CLADDING USING FLEXIBLE CORD OF HARDFACING MATERIAL WITH DIAMOND
Abstract:
A method of hardfacing a component (30) includes generating a laser beam (60) and directing the laser beam (60) to an area of a wear surface of the component (30). The method includes feeding a flexible cord (10) of a cladding material into the laser beam (60) to melt the flexible cord (10) and produce a bead (40) of the cladding material on the wear surface. The flexible cord (10) includes an inner metal wire (26) surrounded by an agglomerate of abrasion and wear-resistant material that contains diamond particles (20). The method further includes moving the laser beam (60) and the flexible cord (10) along the wear surface to produce a cladding layer over the wear surface of the component (30).
