Abstract
Coatings TiCaPCON–Ag with the silver content of 1,0 and 2,5 at.% were obtained by magnetron sputtering. Two types of substrates with different roughness were used for their deposition, notably, polished titanium (average roughness Ra = 20 nm) and the surface modified by pulsed electric-spark treatment (Ra = 8 μm). Structural studies showed that the introduction of silver into the composition of coatings leads to the formation of nanoparticles 5–10 nm in size on their surface. The yield kinetics of silver from coatings into the physiological solution is investigated by mass spectrometry with inductively coupled plasma. It is shown that the yield of silver ions into the biological medium can be controlled due to varying the substrate surface roughness.
