Abstract Metallic implants are used in surgery to treat bone defects or to replace hard tissues. In principle, all metallic implants are subject to corrosion and mechanical wear after implantation. Often, it is difficult to achieve a strong mechanical interlocking between the implant and the surrounding bone, and a potential risk for implant rejection exists. A metallic implant with a biocompatible coating, such as calcium phosphate (CaP), allows the combination of the good mechanical properties of the metal and the good biological properties of the biocompatible coating. This improves the ability of an implant to be intergrated with the host tissues. The most frequently used techniques to prepare biocompatible coatings are plasma spraying, micro-arcoxidation, pulsed laser deposition, electrophoretic deposition, biomimetic crystallization techniques and sol-gel method. These methods have limitations: the elemental composition imbalance, the difficulties in controlling the phase composition, the low value of the adhesive strength of the coating, the limitations in the choice of the base materials, etc.
