主　　题：Corrosion resistance 

摘      要：The main justification for using stainless steels in the production of surgical instruments is their exceptional corrosion resistance and wide range of mechanical qualities, making them very suitable for a wide variety of applications. Typically, stainless steel surgical instruments are used and reused until they degrade. Corrosion is the primary factor leading to the failure of metallic surgical instruments. Corrosion may manifest either gradually or aggressively when the protective layer that forms on the surface of the metallic material is compromised. Corrosion-induced surface flaws may facilitate the contamination of instruments by holding residual substances, which can subsequently result in post-surgical infections. The objective of this study was to examine two prospective coatings, titanium nitride (TiN) and titanium carbonitride (TiCN), that may be applied on surgical tools to reduce the possibility of surface degradation. © 2024, Politechnica University of Bucharest.
