In recent years, coating of metal orthopedic implants with bioactive layers to promote fixation with bones has become increasingly common. Calcium phosphate coatings on the Nitinol surface were formed using two low-temperature methods: sol-gel and electrochemically assisted deposition. The coatings formed were characterized using: X-ray diffraction analysis, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, and Fourier transform infrared spectroscopy. Cyclic voltammetry studies were carried out in the deposition solution to determine parameters for electrodeposition and to understand electrochemistry of deposition. The barrier properties and corrosion resistance of coatings were tested in the physiological Hanks' solution using electrochemical impedance spectroscopy. The sol-gel deposited coating consisted of two phases, hydroxyapatite and tricalcium phosphate (TCP). Apatite coatings containing TCP offered the opportunity to create a grafting material with high bioactivity and bioresorbility. The electrodeposited coating consisted of Ca-deficient HAp which resembles to biological HAp.
