Abstract:
A method of manufacturing a composite article including a ring-shaped single piece substrate having an outer surface and a depression comprising a groove disposed circumferentially in the substrate outer surface and comprising a first material and an inlay within said groove comprising a second material, the method comprising:(a) preheating the single piece ring shaped substrate; (b) contacting the depression in the outer surface of the single piece ring shaped substrate with the inlay second material in the form of a metal wire; (c) heating the inlay second material proximate a point of contact with the substrate causing the second material to liquify and flow into the depression; and (d) moving the point of contact along the depression in the surface of the substrate while continuously feeding and heating the metal wire second material into the depression proximate the point of contact with the substrate to cause it to flow into the depression, moving the point of contact further comprising rotating the ring shaped substrate a plurality of revolutions about an axis of rotation of said ring shaped substrate to move the point of contact along the groove and to at least partially fill the groove with the liquefied metal wire.
