What does passivation provide to surgical instruments?

• A. A shiny finish for aesthetic appeal
• B. A corrosion-resistant finish
• C. A method for sharpening blades
• D. A weight balance to the instruments

Answer: (B)

Passivation is a chemical treatment process applied to stainless steel and other metals to enhance their resistance to corrosion. It involves the creation of a thin, protective oxide layer on the surface of the instruments. This oxide layer serves as a barrier against environmental factors such as moisture and certain chemicals that can lead to rust and degradation of the material.

By improving the corrosion resistance, passivation directly contributes to the longevity and durability of surgical instruments, ensuring they remain safe and effective for use in surgical procedures. While the process may lead to some improvements in appearance, its primary function is to enhance the material's protective qualities. Therefore, the correct answer highlights the essential role passivation plays in maintaining the integrity and performance of surgical instruments in a clinical setting.
