A drill-string liner element includes at least one hardbanding layer. The hardbanding layer includes one or more strands of filler metal, each having a width between 1 and 5 millimeters and deposited in adjacent manner to form a substantially continuous layer over a zone of the element. The hardness in the thickness of the layer varies by less than 10 HRC over the zone.
