MATERIAL REPAIR PROCESS USING LASER AND ULTRASOUND

摘要

A process for repair of a surface (32) of a substrate (30) including the application of an energy beam (40) and vibratory mechanical energy (42) to the surface in a region of a discontinuity (34) in order to form a renewed surface (48) on the substrate. A powdered flux material (36) may be disposed over the discontinuity and melted in order to trap and remove contaminants (28) into a layer of slag (46). The vibratory mechanical energy may be applied to dislodge contaminants within the discontinuity, to add friction heat to the discontinuity, to assist in the flotation of the slag, to remove solidified slag, and/or to provide stress relief of the renewed surface.

主权项

1. A process for repair of a surface of a substrate, the process comprising:
imparting mechanical vibratory energy to the surface in a region of a discontinuity; melting a portion of the surface including the discontinuity with an energy beam to form a melt pool; and allowing the melt pool to solidify to form a renewed surface on the substrate without the discontinuity.
