How to make surgical instruments last

Surgical instruments today are not made to last. I see more and more “instrument pitting.” Pitting a short for “pitting corrosion.” This results in small holes in the metal making it weaker and more likely to break.

What causes pitting corrosion?

For a defect-free “perfect” material, pitting corrosion is caused by the environment–how instruments are stores, how much moisture is in the air, etc. These conditions can contain chemical species such as chloride. Chloride is particularly damaging to the passive film–oxide–so pitting can initiate at oxide breaks.

How to protect your instruments?

I discovered how to remove the pitting before it can destroy the instrument. By removing the pitting on the surface back to the original surface of an instrument will prolong the life and save you from buying new instruments.
