Recent development of calcium phosphate based coating on titanium alloy implants
Titanium alloy implants are widely employed in biomedical devices and components, especially as hard tissue replacements as well as orthopaedic applications, owing to their favourable properties such as high-strength to weight ratio, low density, low Young’s modulus and biocompatibility. However,...

| Summary: | Titanium alloy implants are widely employed in biomedical devices and components, especially as
hard tissue replacements as well as orthopaedic applications, owing to their favourable properties such as
high-strength to weight ratio, low density, low Young’s modulus and biocompatibility. However, metallic
implants cannot meet all of the clinical requirements. Therefore, in order to increase their clinical success and
long term stability in the physiological environment, surface modification is often performed. This review
focuses on the latest achievements in the field of surface modification techniques including sol-gel, thermal
spray, magnetron sputtering, electrophoretic deposition and micro-arc oxidation of biocompatible calcium
phosphates (CaP) based ceramics coatings for metallic implants with emphasis on the structure, morphological
characterization, phase transformation and coating composition. A reflection on the results shows that
CaP coatings can be grown with the each type of techniques and a stronger fixation can be enhanced with CaP
fabrication on metallic implants. Advantages and limitations of the aforementioned techniques of CaP-based
coatings from the point of view of the process simplicity as well as the most important challenges of each coating
techniques are highlighted. Further, the most promising method for CaP deposition was identified and a
specific area for improvement was discussed. |
