Calcium phosphates (CaP), as a group of materials, include the main form of calcium found in the human body as an inorganic component of bones and the main component of dental enamel. Calcium ions and phosphate ions are the source of material for the mineralized formation of bone. Due to their similarity to bones, biocompatibility, and biodegradability, CaP materials are commonly used in the development of new implants for the regeneration of solid tissues. There are different CaP phases that differ in physicochemical properties (such as composition, crystal structure, density, solubility, pH stability range in aqueous solutions, etc.), while in solid tissues CaP appears as biological apatite. In the field of medicine, various CaP materials, with hydroxyapatite being the most prevalent, are used in the form of powders, granules, coatings, etc. CaP coatings have a wide range of applications in medicine, specifically in the fields of orthopedics and dental medicine as bioceramic coatings on metal bone implants or on dental implants. Due to their chemical similarity to bones and teeth, CaP bioceramic coatings have applications in tissue regeneration, fracture treatment and joint replacement. Since titanium alloys exhibit good corrosion resistance, they are considered highly biocompatible. However, to increase their bioactivity, which is crucial for connecting implants to surrounding bone, surface modification is required, where the common principle is the application of a bioactive material coating. Therefore, bioceramic CaP coatings are used as coatings on titanium and titanium alloy metal implants to improve osseointegration. The electrodeposition method is a process of depositing metal or other material coatings onto the surface of a conductive substrate using an electric current. The electrodeposition method represents a relatively simple way to prepare CaP coatings (including hydroxyapatite coatings). Other significant methods for obtaining CaP include plasma spraying, sol-gel deposition, biomimetic deposition, etc.
