Aluminum oxide ceramics with hydroxyapatite

摘要

The invention relates to a method for producing hydroxyapatite coated ceramics components. In a first step of the inventive method the ceramic component is provided with a Ti coating and in a second step a hydroxyapatite is applied to the Ti coating. The invention further relates to hydroxyapatite coated ceramic components produced according to the inventive method.

主权项

1. A method for producing a hydroxyapatite-coated ceramic core component having a Ti-containing layer comprising the steps of:
coating a ceramic core component comprising aluminum oxide with a titanium-containing layer, wherein the titanium-containing layer comprises at least one of Ti or a TiAl6V4-alloy, wherein the titanium-containing layer is up to 5 μm thick, subjecting said titanium-containing layer to a sand blasting process to achieve a roughness of Ra 40 to 50 μm, and applying hydroxyapatite to the roughened titanium-containing layer to form the hydroxyapatite-coated ceramic component having a Ti-containing layer.
