| Summary: | Title screen A coating on the basis of silver-containing hydroxyapatite (silver-hydroxyapatite) was deposited by radio frequency (RF) magnetron sputtering. X-ray diffractometry, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and ellipsometry were used to analyse the change in structure and stoichiometry of the coatings upon the change of the negative electrical bias (-50 V and -100 V) on the substrate. The chemical composition of the sputter-deposited coating was identical to the target. However, an increase in the negative electrical bias on the substrate led to a decrease of the coating thickness. In addition, the average size of the grains decreased from 55 ± 15 nm (grounded substrate) up to 30 ± 10 nm when an electrical bias of -100 V was applied. Silber-dotierte Hydroxylapatit-Beschichtungen wurden durch RF-Magnetron Spritzen hergestellt. Die Abhängigkeit der Schichteigenschaften (Struktur, Stöchiometrie) von der elektrischen Vorspannung (-50 V und -100 V) wurde durch Röntgenbeugung, Rasterelektronenmikroskopie, energiedispersive Röntgenspektroskopie und Ellipsometrie untersucht. Die chemische Zusammensetzung der Beschichtungen war identisch mit der Zusammensetzung des Targets. Eine Erhöhung der elektrisch negativen DC-Vorspannung auf dem Substrat führte zu einer Abnahme der Schichtdicke. Die mittlere Korngröße betrug 55 ± 15 nm bei einem geerdeten Substrat und 30 ± 10 nm bei einer elektrischen Vorspannung von -100 V. |
