Abstract
A process for resurfacing a monocrystalline or directionally solidified metallic piece, having a thickness (Ws), in which a laser beam and a flux of metallic powder, whereof the nature is the same as that of the metallic piece, is applied to the piece to produce at least one layer of metal, monocrystalline or directionally solidified, from the piece, the laser beam being sent out at a power “P”, and moving along the piece at a speed “v”, wherein the laser beam and the flux of powder are applied coaxially on the piece and the P/v ratio is within the range defined on the figure.
