Surface treatments by acid etching and passivation

Technology designed for the medical, dental and traumatology sectors

In the medical implant and orthopedic device sector, the quality of the surface treatment is critical to ensuring biocompatibility, corrosion resistance, and implant stability. At BRIO Ultrasonics, we develop passivation and acid etching machines specifically designed for the manufacturing processes of dental implants, orthopedic components, and other high-precision medical devices.

Our solutions enable controlled acid etching and passivation processes that remove surface contaminants, promote the formation of stable passive layers, and prepare the implant surface to optimize its performance in the body. These processes are especially relevant for materials such as titanium, titanium alloys, and medical-grade stainless steels.

BRIO Ultrasonics passivation machines are designed to meet the demanding requirements of the implantology and traumatology sectors, integrating:

Automated and manual multi-stage processes for acid etching, rinsing, neutralization and passivation.
Precise control of parameters such as temperature, time, chemical concentration, and agitation.
Compatibility with cleanrooms and medical manufacturing environments.
Building materials highly resistant to acids and aggressive chemicals.
Automatic handling systems for baskets or parts holders, which guarantee repeatability and traceability of the process.
Integration with cleaning, anodizing, electropolishing or other lines.
Filtration systems, chemical control and bathroom management.
PLC control and recording of process parameters for traceability.

With our experience in surface treatments for the medical sector, we help manufacturers achieve safe, repeatable processes that comply with the quality standards of the healthcare sector.
