Metal-on-Metal Hip Replacement Electrochemical Data Under Simulated Walking

Raw electrochemical data for a 28mm Metal-on-Metal Total Hip Replacement bearing articulated under an ISO walking profile. The data includes open circuit potential and anodic polarization measurements at different cycle frequencies and daily living cycles, with processed results comparing anodic current to theoretical minimum film thickness. The dataset was contributed by Andrew R. Beadling from the University of Leeds.

Use Cases

• Modeling the relationship between electrochemical activity and lubrication film thickness based on the described anodic current and film thickness calculations.
• Analyzing the effect of articulation frequency on corrosion behavior using the raw OCP and anodic polarization data.
• Validating simplified 2D models and Hamrock-Dowson equation expressions for implant tribology using the provided processed results.

Strengths

• Data is collected under a standardized ISO walking profile, providing a controlled experimental context.
• Includes both raw electrochemical measurements (OCP, anodic polarization) and processed results linking current to film thickness.
• Focuses on a specific 28mm Metal-on-Metal Total Hip Replacement bearing, a clinically relevant implant size.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
