Apatite Coating

Sand-blasting treatment and chemically biomimetic growth are important methods improving the interface adhesion strength and formation of osteoconductive coatings for implants. In the present study, these methods were employed to generate bone-like apatite coating on Ti6Al4V spinal fusion devices. The surface morphology, elements and microstructure were analyzed using SEM, AFM, EDS, XRD and TEM. The results showed that bone-like apatite layer formed after sand blasting treatment and chemically biomimetic growth. Also the dimensional accuracy of device after the treatment could meet the implantation requirement of the device. The coating adhesion test suggests that rough surface after sand-blasting can improve the coating adhesion strength. The study will facilitate further the engineering application of chemically biomimetic growth in surface modification of Ti6Al4V implants and the medical application of spinal fusion device.

In order to improve the osteoblast growth and bacteria resistance, Zn-containing hydroxyapatite (Zn-HA) and titanium oxide (TiO2) composite coatings were prepared to improve binding between coating and Ti substrate. TiO2 film was prepared on the surface of Ti by micro-arc oxidation (MAO) and Zn-HA coating was deposited on TiO2 using sol–gel technique. Phase structure, composition and microstructure of the surface coatings were analyzed by X-ray diffraction (XRD) and Energy Dispersive Spectrometer (EDS), respectively. The adhesion strength between the coatings with different Zn content was measured by tensile testing. The results showed that there was no significant influence of Zn content on adhesion strength between coating and Ti substrate.

This study investigates how roughness and coatability of sheet moulding compound (SMC) components can be improved by modifying the surface morphology of the compression tool. A modular tool was developed that allowed to mould SMC work pieces simultaneously with different tool surfaces. In this study, mainly the tool roughness was modified using various surface treatments. Three different SMC formulations were applied to mould 2D components using the modular system. It was found that the demoulding was affected by both the tool morphology and the SMC formulations. Contamination of the tool by SMC material could be reduced by chrome-plating. The morphology of the tool was transferred to the SMC work piece if the structures were larger than 5 µm. The adhesion strength of a coating system differed for the three SMC formulations. While two of them showed generally good coatability, the coating adhesion on the third formulation decreased with increasing roughness of the tool used for moulding.
