Common alloys: 316L stainless, cobalt‑chrome, titanium (Ti‑6Al‑4V). Corrosion mechanisms: fretting at modular junctions, crevice under plates, galvanic with dissimilar metals. Clinical sequelae: metal ion release, ALVAL, osteolysis, trunnionosis in THA. Prevention: material pairing, surface finish, avoiding fluid‑filled crevices, firm taper assembly.
