New Coating Solutions for Biomedical Applications

Crystallized calcium carbonate, CaCO₃, is a mineral phase that occurs in nature as aragonite. It is well known that CaCO₃ shows excellent chemical interaction and intensive binding in direct contact to bone structures. This paper discusses the development of a plasma spraying process that shows promise for producing dense calcium carbonate layers with good adhesion properties. Tests reveal that the resulting coatings are fully biocompatible and have faster resorption times than plasma sprayed hydroxyapatite. Paper includes a German-language abstract.
