Abstract: A welded assembly includes a first object, a second object, and an interlayer. The interlayer is an ESD coating deposited on the first object, and the second object is welded to the coating. The second object may be a material that has thermally sensitive properties, such as a shape-memory material. The second weld may also be made by ESD. The interlayer may be made of more than one layer. The layer or layers may be deposited of a material chosen for its compatibility with one, the other, or both of the material of the first object and the material of the second object.

Abstract: A welded assembly includes a first object or substrate, an interlayer, and a subsequent layer deposited on the interlayer. The interlayer is an ESD coating deposited on the first object, and the subsequent layer is deposited by ESD on the interlayer. The subsequent layer is made of a different materials from the substrate. Both the interlayer and the subsequent layer are subject to peening. In one case the interlayer has a lower either a lower thermal conductivity or a lower electrical conductivity than the substrate and the subsequent layer. In another example, the subsequent layer has a cermet content of greater than 40 % by wt.
