Abstract

A quantitative analysis of calcium phosphate (CP) layers deposited on metallic titanium substrates was carried out by X-ray fluorescence spectrometry (XRF) in order to evaluate the osteogenic capability of metallic biomaterials. The titanium substrates were prepared by NaOH and heat treatments, and then, they were soaked in Hanks' balanced saline solution (HBSS) at 310 K, leading to the deposition of a CP layer on the sample surface. The resulting samples were analyzed by XRF, and the amount of Ca and P in the CP layers was determined by inductively coupled plasma optical emission spectrometry (ICP-OES). As a result, calibration curves were obtained for determining the amounts of Ca, P and the CP deposition; the XRF quantification of the CP layers was carried out with good accuracy.
