“…All these features enable the application of DLC coatings with prospective potential. In a related study, hemocompatibility of La 2 O 3 -doped DLC films increased with increasing of sp 2 -bonded C content (91). In an earlier study, tetrahedral amorphous carbon (ta-C) showed improved anticoagulation compared to LTIC (74).…”

“…Furthermore, the platelets on the MAO coating were unevenly dispersed, with some regions exhibiting higher platelet density than those on the HA-containing coating. Generally, the sample with less platelet density adhering on the surface indicates improved blood compatibility [46]. The SEM micrographs also provided information on the morphology of adhered platelets and their activation state.…”

Ceramic coatings containing hydroxyapatite (HA) were fabricated on a biodegradable Mg 66 Zn 29 Ca 5 magnesium alloy through micro-arc oxidation by adding HA particles into the electrolytes. The phase composition and surface morphology of the coatings were characterized by X-ray diffraction and scanning electron microscopy analyses, respectively. Electrochemical experiments and immersion tests were performed in Hank's solution at 37 • C to measure the corrosion resistance of the coatings. Blood compatibility was evaluated by in vitro blood platelet adhesion tests and static water contact angle measurement. The results show that the typical ceramic coatings with a porous structure were prepared on the magnesium alloy surface with the main phases of MgO and MgSiO 3 and a small amount of Mg 3 (PO 4 ) 2 and HA. The optimal surface morphology appeared at HA concentration of 0.4 g/L. The electrochemical experiments and immersion tests reveal a significant improvement in the corrosion resistance of the ceramic coatings containing HA compared with the coatings without HA or bare Mg 66 Zn 29 Ca 5 magnesium alloy. The static water contact angle of the HA-containing ceramic coatings is 18.7 • , which is lower than that of the coatings without HA (40.1 • ). The in vitro blood platelet adhesion tests indicate that the HA-containing ceramic coatings possess improved blood compatibility compared with the coatings without HA. Utilizing HA-containing ceramic coatings may be an effective way to improve the surface biocompatibility and corrosion resistance of magnesium alloys.
