Although metals provide good mechanical properties§such as fracture toughness, fatigue resistance and§strong load bearing properties, they are still§susceptible to encountering surface abrasion and§wear. These local deformations on metal surfaces§cause passive film instability or breakdown and the§subsequent cascading events result in spontaneous§electrochemical interactions to regain§electrochemical stability. This transient phenomenon§often leads to corrosion, defined as the electrochemical attack on metal surfaces. Tribology§studies done in metal implant applications have shown§that corrosion is accelerated during mechanical§events such as fretting and wear.§This study presents two commonly used medical implant§applications, modular hip tapers and cardiovascular§stents. We present a test setup for each of these§implants to estimate the effects of fretting corrosion.
