ABSTRACT:
A layer of material is interposed between a metallic texture coating and the substrate of a component of a prosthetic implant, the layer being bonded to the substrate and, in turn, receiving the metallic texture coating so as to deter propagation of fatigue-induced cracks from the metallic texture coating into the substrate.
