MEDICAL PVD COATINGS (TiN)
Protection and durability for implants and surgical instruments
Biocompatibility is a crucial requirement for Titanium Nitride (TiN) coatings, which are applied to implants, abutments, and surgical instruments in the medical industry. These coatings provide not only exceptional protection but also contribute significantly to the safety and effectiveness of medical devices.
Metals used in biological environments are constantly at risk of corrosion, as biological fluids can be highly corrosive to metals. Metal ions released through corrosion can have severe consequences, including:
- Loss of function due to the degradation of mechanical properties;
- Contamination of surrounding tissues and the body with toxic metal ions, potentially causing significant health issues.
These risks make PVD coatings essential for medical components that come into contact with the human body. Such coatings are particularly vital in fields like surgery, orthopedics, dentistry, and orthodontics.
Surgical instruments such as scalpels, blades, and cannulas benefit greatly from the exceptional properties of TiN coatings: they provide smooth glide, high biocompatibility, and enhanced abrasion resistance. For tools like drills, reamers, and surgical bone taps, the high-quality surface finish improves cleanability and extends the lifespan of the instruments.
PVD coatings create an inert surface barrier that protects materials from corrosion, increases wear resistance, and maintains cutting edges for longer. The low friction coefficient of the coating also prevents tissue adhesion to instruments, improving both efficiency and safety in medical applications.
