Abstract Scope |
Additive manufacturing (AM) techniques such as directed energy deposition (DED) and selective laser melting (SLM) are starting to gain momentum to produce parts used in structural and biomedical applications. With the advent of newer manufacturing techniques and parameters, it has become important to study the effect of these on the corrosion resistance and development of micro-galvanic cells that could lead to localized dissolution from specific active locations. This work aims to study the corrosion and tribo-corrosion behavior of stainless steel 316L manufactured using DED and SLM in conditions simulating the inflamed joint after a total hip/knee replacement to attempt to identify unfavorable microstructural features. The individual effect of hyaluronic acid, bovine serum albumin and γ – globulin on the passive film characteristics will be studied to determine the effect of the manufacturing technique on these properties. |
