Electrochemical Corrosion Testing of Cobalt Chromium Alloy for Implantable Devices

Cobalt chromium alloy is a preferred material in implantable medical devices due to its superior strength, biocompatibility, and resistance to corrosion. However, to ensure long-term performance inside the human body, thorough electrochemical corrosion testing is essential.

At TCR Engineering, we perform electrochemical corrosion testing of cobalt chromium alloys in full compliance with ASTM F2129-17 and ISO 5840-1:2020-21 standards. These international standards guide the evaluation of corrosion susceptibility under simulated physiological conditions, critical for implant safety and durability.

• ASTM F2129-17 involves cyclic potentiodynamic polarization testing to assess the localized corrosion behavior of small medical implants.

• ISO 5840-1:2020-21 provides general testing requirements for cardiovascular implants, such as heart valves, including material evaluation protocols.

Our testing environment simulates physiological conditions—mimicking human body temperature, pH, and saline concentrations—to accurately measure electrochemical parameters like corrosion potential, breakdown potential, and repassivation potential.

Lead Time: 10–12 working days after receipt of the sample.

This testing ensures the alloy maintains its structural and chemical integrity throughout its in-body service life and meets global regulatory standards. It's an essential part of the validation process for manufacturers developing implantable medical devices.

By offering precise, standards-based testing with timely delivery, TCR Engineering helps ensure the safety, reliability, and approval readiness of your implant-grade materials.
