) are used in stomatology and orthopedic surgery as an original structure for production of medical materials. These coatings have been deposited on Si, Ti and VT15-alloy substrates from ablation plasma formed under the impact of pulsed high-power ion beams on a calcium phosphate ceramic target. The nanohardness, Young’s modulus, elastic recovery, adhesion of coatings to substrates, friction constant, and surface roughness were measured.
