BIO TDC® Surgical Plating

Surgical plating is used to improve the performance and service life of reusable medical instruments and devices. Depending on the coating system, benefits may include improved wear resistance, corrosion protection, reduced friction, enhanced cleanability, and greater durability under repeated sterilization cycles.

For surgical applications, coatings must also maintain sharp cutting edges, support smooth instrument movement, reduce glare under operating room lighting, and withstand repeated exposure to autoclaving, cleaning chemicals, and other decontamination processes. BIO TDC® Surgical Plating combines a biocompatible micronodular chromium surface with high hardness, corrosion resistance, lubricity, and low-friction characteristics, making it well-suited for demanding medical environments.

BIO TDC helps reduce friction, resist galling, improve wear resistance, and protect against corrosion caused by repeated cleaning and sterilization. The coating’s thin, uniform deposit helps preserve critical dimensions, sharp cutting edges, and mating surfaces while providing a durable, easy-to-clean chromium surface.

Its engineered micronodular structure also helps reduce the real area of contact between moving components, supporting smoother operation and long-term surface performance in high-cycle medical applications.

Yes. BIO TDC is designed for reusable medical instruments and devices exposed to repeated sterilization and cleaning cycles. The coating is compatible with steam autoclave sterilization, STERIS SYSTEM 1 processing, STERRAD sterilization systems, and other medical cleaning environments that can contribute to corrosion and surface degradation.

Micronodular thin dense chrome coatings utilize a controlled nodular surface structure that helps reduce the real area of contact between mating surfaces. This engineered topography can help lower friction, improve wear resistance, and reduce the potential for adhesive wear and galling.

In medical applications, the micronodular surface also supports cleanability and long-term surface durability while maintaining the dimensional precision required for surgical instruments and medical devices.

BIO TDC is commonly applied to reusable surgical instruments, orthopedic tooling, endoscopic components, robotic surgical assemblies, veterinary surgical instruments, and medical manufacturing tooling.

Typical applications include forceps, clamps, retractors, scissors, drills, reamers, cutting instruments, and other precision medical components requiring biocompatibility, corrosion resistance, wear protection, and sterilization durability.

When evaluating surgical coating providers, medical manufacturers typically consider coating consistency, dimensional control, biocompatibility testing, process validation, inspection capabilities, sterilization compatibility, and experience supporting medical device production.

A qualified surgical coating supplier should be able to provide repeatable coating performance, engineering support, quality documentation, and the process controls necessary to support both prototype and production medical applications. For applications requiring biocompatibility, sterilization resistance, and precision dimensional control, contact Armoloy’s engineering team to help evaluate whether BIO TDC is the right fit for your medical device or surgical instrument.
