Abstract
Alloys of cast Co‐Cr‐Mo, wrought Co‐Cr‐W, wrought Co‐Ni‐Cr‐Mo (MP35N), Ti‐6% Al‐4% V, and graphite were incorporated in specimens which simulated both a couple and a crevice corrosion condition. These specimens were implanted in a dog for 30 months. Post‐sacrifice examination showed no substantial evidence of corrosion activity on the surfaces of the metals except for a tarnish film on the titanium alloy specimens. The presence of the tarnish film is taken as some evidence of corrosion activity and this correlated with a thicker average fibrous membrane, cellular activity in and near the fibrous membrane, and some increased vascularity. These must be regarded as preliminary observations.This publication has 3 references indexed in Scilit:
