Wear and Corrosion Resistance Improvement of CoCrMo alloy by Tantalum Based Coatings
… short lifetime of the prosthesis. Medical grade CoCrMo alloy is one of the most common materials used for femoral head fabrication. Unfortunately, the implant fails usually after 15 years of service due to the excessive wear of the polyethylene liner and corrosion of the metallic ball which …

The effects of simulated inflammatory conditions on the corrosion and fretting corrosion of CoCrMo alloy
<p>In vivo corrosion of CoCrMo alloy and its potential adverse effects on the body have been recognized as major concerns in recent years. While the underlying concepts of general and mechanically-assisted corrosion have been well documented, recent report of inflammatory cell-induced corrosion …

Synthesis and Characterization of Ag and Cu doped DLC Thin Films for Anti-microbial Applications
… thin films were deposited on biomedical grade CoCrMo alloy discs using DC magnetron sputtering. The concentrations of Ag and Cu in the DLC matrix were controlled by varying the pulsed DC power to the Ag and Cu targets. The films' chemical composition, morphology, and bonding states of the films …

Voltage Effects on Cells Cultured On Metallic Biomedical Implants
… work, changes in the interfacial properties of a CoCrMo biomedical alloy (ASTM F-1537) in phosphate-buffered saline (PBS) (pH 7.4) at different voltages was studied. Step polarization impedance spectroscopy technique was used to apply 50 mV voltage steps to samples, and the time-based current …

Iatrogenic Electrocautery Damage and Cellular-Based Corrosion of Total Joint Arthroplasty Biomaterials
… functional deficit. Cobalt-Chromium-Molybdenum (CoCrMo) alloy is one of the most used materials in Total Joint Arthroplasty (TJA) implants due the material’s high strength, high corrosion resistance, and biocompatibility. The release of metal ions and potential occurrence of metallosis in TJA has …

Tribological and Structural Characterisation of Ceramic on Metal Hip Replacements
… alumina (ZTA)), were articulated against as-cast CoCrMo alloy cups. The diameter was changed from 38 mm to 60 mm to explore the effect of diameter on the tribological performance. Three distinct wear tests were undertaken to allow a direct comparison between materials and sizes. These were; wear …

Investigating Synovial Fluid Electrochemical Properties Against Orthopaedic Alloys
<p>Introduction. Cobalt-chromium-molybdenum (CoCrMo) femoral components are widely used in total knee arthroplasty (TKA). However, recent retrospective clinical trials associate moderate adverse local tissue reactions (ALTRs) with CoCrMo release in the knee. Additionally, gaps persist in our …
