Influence of Proteins and Building Direction on the Corrosion and Tribocorrosion of CoCrMo Fabricated by Laser Powder Bed Fusion

“…Still, they can also increase the chemical degradation rates affecting corrosion and tribocorrosion. ,− They also seem to play an important role in the formation of so-called tribolayers, which can reduce the coefficient of friction (COF). , Proteins are very variable and may influence the tribocorrosion behavior of CoCrMo alloys in multiple ways and as a function of the microstructure. Recent review papers on additively manufactured biomaterials have underscored the necessity for comprehensive research efforts to address critical questions in this field. − To the best of our knowledge, there have not been any systematic studies on the tribocorrosion behavior of CoCrMo as a function of manufacturing and protein type.…”
