Metallic biomaterials are commonly used in both
medical devices and the human body. It is effectively
used as a surgical intervention in the treatment of
different parts of the human body. The environment in
the human body differs physically and chemically. The
fluid in the body (physiological environment) creates a
corrosive environment for metal implants because it
contains various aggressive ions. Corrosion of
biomaterials leads to loss of surface functions and
structural integrity. The released corrosion products
cause allergic reactions, local pain and swelling. For
this reason, it is necessary to characterize the corrosion
properties of metallic biomaterials. In this study, 316L,
CP-Ti, Ti45Nb and Ti6Al4V were selected among the
metallic biomaterials and their corrosion and flow
accelerated corrosion (FAC) resistance were
investigated. The tests were performed in Simulated
Body Fluid (SBF) by taking Open Circuit Potential
(OCP) and Potentiodynamic Polarization (POTDYN)
measurements. Flow accelerated corrosion (FAC) tests
were performed using a peristaltic pump at a flow rate
of 10 ml/s. XRD analyzes of the four groups of
materials used were made. The corrosion and FAC
performances of these samples were compared.
