This work presents a study on an alternative coating method based on electrochemical techniques which are designed to form a crystalline hydroxyapatite layer very similar to the process corresponding to the formation of natural bone. In this study, a sample electrochemical method of coating the solid surfaces of zinc, with a film of apatite, was developed. The hydroxyapatite deposit was investigated by means of scanning electron microscopy, X-ray diffraction, infrared spectroscopy, and chemical analysis. The data suggest that the method utilized in this work can be successfully applied to obtain deposition of uniform coatings of crystalline hydroxyapatite on zinc substrates. As a result, both the lattice parameters a and c of the apatite layer decreased with increasing Zn fraction.
