Corrosion resistance and biocompatibility of SrHAp/ZnO composite implant coating on titanium

- The SrHAp/ZnO coating was formed on Ti substrate by CED for the first time.
- The SrHAp/ZnO layer was dense and uniform, with a flocculent morphology.
- The SrHAp/ZnO coating showed higher corrosion resistance than pure HAp coating.
- The SrHAp/ZnO coating was better to enhance the biocompatibility compared with the bare Ti.
