Analysis of energy dissipation in fretting corrosion experiments with materials used as hip prosthesis

This paper analyses energy dissipation of fretting corrosion in total hip prosthesis. Fretting corrosion is arisen between metallic prosthesis and bone and/or bone cement, leading to aseptic loosening. In this study, fretting corrosion tests are conducted in Ringer's solution. Stainless steel (...

Description
Summary:This paper analyses energy dissipation of fretting corrosion in total hip prosthesis. Fretting corrosion is arisen between metallic prosthesis and bone and/or bone cement, leading to aseptic loosening. In this study, fretting corrosion tests are conducted in Ringer's solution. Stainless steel (316L) and poly (methyl methacrylate) are used for total hip prosthesis. Various potentials are applied in fretting corrosion tests and then dissipated energy is determined with number of cycles. Results show that dissipated energy is rapidly accumulated during the initial running-in period and accumulation of dissipated energy change can be expressed with a power-law form. After the initial running-in period, dissipated energy is linearly accumulated with respect to number of cycles. It is identified that a parameter in the power-law relation can describe the influence of applied potentials in fretting corrosion. In addition, the parameter shows relation to wear volume measured in stainless steel. ► Energy dissipation of fretting corrosion in total hip prosthesis is investigated. ► Dissipated energy is rapidly accumulated during the initial running-in period and accumulation of dissipated energy change can be expressed with a power-law form. ► A parameter in the power-law relation can describe the influence of applied potentials in fretting corrosion. ► The parameter shows relation to wear volume measured in stainless steel.
