Аннотация

TiSiN thin films were deposited on Ni-Cr dental alloy in order to enhance the corrosion resistance in artificial saliva with and without fluoride content. The TiSiN films were prepared using reactive cathodic arc method at two different substrate bias voltages (-50 V and -200 V). For the corrosion evaluation, artificial saliva with pH=5.2 was chosen, because this is a critical value for mineral dissolution of dental tissue which can affect the dental alloys. A content of 0.1 % NaF was added to the artificial saliva to simulate the effect of fluoride based hygiene products. The TiSiN coated Ni-Cr alloys exhibited a higher corrosion resistance than the Ni-Cr substrate, irrespective of the testing environment. The best corrosion resistance was found for the TiSiN deposited at -200 V.
