Friction Welded Insert and Processes for Inserting the Insert into a Substrate

摘要

A method for attaching an insert to a substrate includes: rubbing the insert against the substrate; forming a heat-affected zone in the substrate; forming plasticized substrate material from friction resulting from the rubbing; moving the insert to a first depth in the heat-affected zone in the substrate; moving the insert to a second depth in the heat-affected zone in the substrate where the first depth is deeper than the second depth; flowing the plasticized material against the insert; and releasing the insert.

1. An insert, comprising:
a body, having an engaging portion and a free portion located opposite the engaging portion; a side portion of the body defining a retention cavity, the retention cavity being located closer to the engaging portion than the free portion; a junction between the retention cavity on a side of the portion defining a rounded surface; and a protrusion extending from a surface on the engaging portion.
