Medical Coating
Creating More Effective Medical Instruments
Enhancing Applications Across the Medical Industry Worldwide
The Armoloy Corporation helps medical professionals protect their high-precision devices and instruments with our biocompatible medical coatings.
ME92, initially designed for surgical instruments, is the preferred solution for use in lab environments, cleanrooms, and a wide range of medical applications, and it’s also well-suited for food processing equipment. This preference arises from the process’s exceptional cleanliness and minimal exposure to contact materials. ME92 improves lubrication properties, is chemical resistant, easy to clean, and strengthens metal surfaces for wear and corrosion applications as well. With multi-value attributes and benefits, ME92 prolongs the lifespan of critical equipment, enhances performance consistency, and effectively eliminates contamination risks. The ME92 process also offers multiple sheen and color variations to cater to non-reflective applications and meet aesthetic preferences.

The Science Behind ME-92
How it Works
The design of the Armoloy’s ME-92 pure biocompatible chromium coating makes it uniquely engineered to serve the medical industry. Applied with the utmost precision, this coating is completely inert and developed in a highly sanitized facility free of latex to meet all necessary compliance measures.
The process for developing ME-92 medical coating will begin by obtaining customer’s individual production requirements—including finish, deposit thickness, and more. When developing the ME-92 coating, our team of experts utilize electrolytic plating and a low-temperature process to uniformly apply the pure metallic chromium. This process ensures that the integrity of the application’s material remains intact.
By bonding the coating to the application’s material, Armoloy ensures absolute adhesion and high ductility. This means that the coating will not only prevent chips, flakes, and peels, but also any separation from the material under stress. The end result is a dramatic improvement to the instrument’s appearance and performance—as well as its longevity by:
- Increasing wear and corrosion resistance
- Improving surface hardness and chemical resistance
- And eliminating galling
