Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

High-frequency magnetron sputtering (HFMS) at various plasma powers has been applied to obtaining hydroxyapatite (HA) coating with amorphous and crystalline structure on VT1-0 titanium. The results concerning the influence of thermal treatment on the coating under isothermal holding for 1 h at 700–1000°C are presented. Structure, phase composition, topography and morphology of the formed hydroxyapatite coatings have been analyzed by X-ray phase analysis, scanning electron microscopy, energy-dispersive spectroscopy, atomic-force microscopy, and IR spectrometry. It is found that, depending on discharge power and temperature of isothermal annealing, molecular bonds are formed that are typical for HA accompanied by variations in phase and elemental compositions.
