Joining between metal and polymer has attracted significant attention recently due to its advantage of great weight reduction and excellent integrated physical/chemical properties. In this study, specially designed biomedical additive manufactured porous TC4 titanium alloy plate was successfully joined to ultra-high molecular weight polyethylene (UHMWPE) plate by friction spot welding (FSpW). The z-axial load (Fz) evolution has been measured with load cell, and welding temperature (Tw) near TC4/UHMWPE interface has been measured with thermocouple. High tensile shear strength (~3000 N) has been realized through strong mechanical interlocking. Good macro-penetration of UHMWPE into TC4 porous structure (up to 80% filling rate) and sound micro-interlocking between metal and polymer were obtained. Relationship between Tw/Fz and joint quality has been unveiled for the fabrication of defect-less joints.
