Metallic Medical Device Corrosion Testing and Failure Analysis

Failure Analysis & Metallurgical Characterization

We investigate failure mechanisms in implants and surgical components using fracture analysis, microstructural evaluation, and chemical testing. These insights support root cause identification, quality improvement, and design optimization.

Corrosion Testing in Simulated Body Fluids

Electrochemical tests are performed under simulated physiological conditions. This is done to determine corrosion rates, damage progression, and comparative performance across different materials, coatings, and surface treatments.

Pitting & Crevice Corrosion Evaluation

Using methods like cyclic potentiodynamic polarization (ASTM F2129) and crevice corrosion protocols (ASTM F746), we assess susceptibility to localized attack—critical for the long-term integrity of orthopedic, spinal, and cardiovascular implants.

Galvanic Coupling Analysis

Modern implant systems often combine dissimilar metals. We evaluate galvanic interactions in accordance with ASTM F3044, identifying vulnerable interfaces in modular designs and mixed-metal assemblies.

Metal Ion Release Testing

We perform ion release and leaching studies following ASTM F3306 to measure the release of potentially harmful metal ions under physiological conditions. This data supports toxicological assessments and regulatory submissions.

Customized Testing Protocols

When standard methods fall short, we develop application-specific protocols that incorporate real-world mechanical, chemical, and environmental stressors to evaluate device performance and material degradation over time.
