Abstract:
1. An article suitable for arc-welded metallurgical bonding, the article comprising: a first part having a lower surface; and a second part having an upper surface, the lower surface of the first part disposed at the upper surface of the second part to provide for a faying surface thereat; wherein the faying surface comprises a plurality of channels having a depth equal to or greater than about 1 micron and equal to or less than about 1000 microns, the article being suitable for arc-welded metallurgical bonding at the faying surface; wherein the plurality of channels comprises a repetitive pattern of channels arranged along a path of the faying surface in a direction of the metallurgical bonding action; wherein the repetitive pattern of channels comprises a pattern of intersecting linear lines, curvilinear lines, or both, with the intersection of the intersecting lines or a point of curvature of the curvilinear lines arranged proximate to and along a path of the faying surface in the direction of the metallurgical bonding action.
