Passivation of surgical instruments, implants and other medical devices made of stainless steel
To achieve optimum corrosion protection, it is imperative that stainless-steel instruments and implants be subjected to sufficient passivation. This applies in particular after marking by means of etching or laser. There are several methods to restore or improve the formation of a passive layer. Electropolishing, nitric acid and other methods have yielded the desired results in the past, but were also associated with various environmental and safety problems.
