Comparison Study on the Properties of the CaP Coatings Formed by RF-magnetron Sputtering of the Mg- and Sr-substituted β-tricalcium Phosphate and Hydroxyapatite

This article describes the influence of Mg and Sr substitutions in the structure of β-tricalcium phosphate and hydroxyapatite powder targets on the deposition rate of coatings formed via RF-magnetron sputtering and their properties. It was revealed that even low doses of ionic substitutions in β-tricalcium phosphate significantly affect deposition rate, morphology and physico-chemical properties of respective coatings. Similar doses of these substitutions in hydroxyapatite are not enough to influence the deposition rate, but they affect coating properties.
