Abstract
This tool design provides a hardened or abrasive surface to essentially scratch the stronger material of a dissimilar metal joint. The abrasive tip is located on the pin of a traditional friction stir tool, such that the temperature and pressure of the FSW process allows the softer material from the dissimilar stack to flow into and around the roughened surface of the harder base material.
