The application of PVD coatings on in vivo medical devices is mainly to enhance wear resistance, biocompatibility and to stop ionic spillage, etc. The application of PVD coatings in medical devices started in the late 1980s and has been widely used in a variety of medical devices, including orthopaedic implants, pacemakers, surgical forceps, etc. In the case of in vivo medical devices, the application of PVD coatings is particularly critical as they provide a protective layer of wear and corrosion resistance, which is particularly important for long-term implantation in the human body.
The application of PVD coatings is particularly critical in in vivo medical devices, as it provides a wear and corrosion resistant protective layer, which is especially important for medical devices that are implanted in the human body over a long period of time. In addition, PVD coatings offer excellent compatibility with blood and act as a chemical barrier to stop ion spillage from the alloy material, which is critical to reducing biological rejection and improving the biocompatibility of the device.
PVD coatings are available in a wide range of colours and hardnesses, including titanium nitride (TiN) and chromium nitride (CrN), to meet the performance needs of different medical devices.
