The method of making an implant consists on coating of a supporting structure () with synthetic hydroxyapatite by immersing the supporting structure () in a suspension () and triggering of a cavitation in a portion of the suspension () being in contact with the supporting structure (). The suspension () is formed by a liquid external phase, advantageously water, and internal phase, i.e. particles of synthetic hydroxyapatite having an average particle size not exceeding 100 nm and containing structural water in an amount from 2 to 6% by weight. The implant is coated with the above described hydroxyapatite subjected to cavitation and a thickness of 50 nm to 1000 nm, advantageously 50 nm to 300 nm.

Method for manufacturing bone implants and bone implant

A composite coating and method for preparing the composite coating on titanium implants for tissue culture and tissue engineering is provided. The implants are characterized in that the titanium component to be coated is placed in a aqueous solution containing calcium cations, phosphate anions, and dispersed carbon nanoparticles (such as single layer graphene oxide or graphene oxide) in an amount of about 0.05%-1.50% by weight relative to the total weight of aqueous solution. The dimensions of the dispersed graphene oxide should be around, but not limited to, 300-800 nm (X-Y), while their thickness is about 0.7-1.2 nm. The aqueous solution with carbon nanoparticles is prepared by mixing for at least 72 h in temperature in range 20-35&#xb0; C. and sonicated before electrodeposition process. In the prepared solution is further placed titanium which acts as cathode element (may be the implant), and anode which can be, for example, a platinum rod. Between the cathode and anode is set a potential from &#x2212;1.3V to &#x2212;1.7V which results in coating formation by electrodeposition. The titanium implant before the electrodeposition process is treated in sodium hydroxide of HF to improve coating formation and thickness.
