A unique parallel-plate flow chamber has been engineered to assess the corrosion properties of implant materials in biological environments under shear flow. This parallel-plate flow chamber provides a novel approach to investigate hypotheses regarding cellular-material-mechanical-force interactions that influence the success or failure of implant devices. The results of the current study demonstrated that physiological stresses (0.5-50 dynes/cm2) from laminar flow from cell culture media did not significantly alter corrosion rates of stainless steel, providing baseline information for an extensive study of the cellular-material-mechanical-force interactions. Furthermore, this study demonstrated that this device is electrochemically stable and provides reproducible results within test parameters. In addition, the results were not significantly different from corrosion tests on bulk samples. Therefore, this system will be useful for investigating cell-material interactions under shear stress for implant alloys or other opaque materials. This information is currently lacking. The results of the present study also support further development of this test system to assess cellular responses to these materials under shear stresses.
