Bioactivity of Plasma Sprayed Calcium Silicate/ZrO2 Composite Coatings
In this work, 30wt％ calcium silicate, including wollastonite and dicalcium silicate, were mixed with 70wt％ ZrO2, respectively. The composite powders were deposited onto Ti-6Al-4V substrates to prepare wollastonite/ZrO2 and dicalcium silcate/ZrO2 composite coatings using plasma spraying technology. The bioactivity of coatings was evaluated using simulated body fluid soaking test. After the composite coatings were soaked in simulated body fluid for a certain period, apatite was formed on the surface of the wollastonite/ZrO2 and dicalcium silcate/ZrO2 composite coatings. In addition, the ZrO2 in composite coatings may protect the calcium silicate in the coatings from dissolving in simulated body fluid.
