Abstract

In this research, nanolayered TiN layers were deposited on dental materials (titanium alloy, Co-Cr alloy, Yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) and stainless steel (AISI 316) raw materials) by RF magnetron sputtering. Microstructure, surface topography, nanomechancial properties and elastic properties of TiN coated dental materials were analyzed using by atomic force microscopy (AFM). Stoichiometric ratio of N/Ti is ½. Penetration depth is arranged 5 nm, 10 nm, 15 nm and 250-400 nm. Nanomechanical and Young modulus were determined by depth sensing indentation test. Furthermore, nanohardness value of the stainless steel samples were increased to level of Y-TZP samples by TiN coatings..
