Properties of calcium phosphate coatings deposited by high-power ion beam ablation plasma

Mechanical Properties of Zn-Ni-SiO_2 Coating Deposited under X-ray Irradiation

“…Since such an empirical parameter as elastic recovery characterizes the coating yield point, its decreasing indicates that the coating becomes less elastic to increase the possibility of cracking [11].…”

Influence of the high-power ion-beam irradiation of a hydroxyapatite target on the properties of formed calcium phosphate coatings

“…These values are somewhat less than the stoichiometric Ca : P ratio in HAP, which is 1.67. In other experiments on the deposition of CP coatings under exposure to HPPIBs, the Ca : P ratios were closer to the stoichiometric value [4,5]. This can be caused by a distinction between the HPPIB and target parameters.…”

“…It was confirmed that these coatings are untoxic and apyrogenic, do not give rise to degenerative changes in tissue during implantation, and meet the requirements of regula tions. However, they are deposited at very low rates (no more than several nanometers within a single beam current pulse) [4][5][6][7]. However, there is no explicitness in the question as to whether the accelerator operation modes used in experiments are optimal from the standpoint of the energy efficient obtainment of a deposited material.…”

“…In addition, a large treat ment area (tens of square centimeters) and acceptable efficiency are achieved [1][2][3]. With the help of HPPIBs, a biocompatible calcium phosphate (CP) coating can be deposited onto the surfaces of different implants used in dentistry, traumatology, and orthope dics [4][5][6]. The base of these products is most often fabricated from titanium and its alloys or corrosion resistant high quality steel, and CP coatings stimulate the osteogenesis of bone tissues and implant fixing due to the coalescence of the coating material and bone.…”

Deposition of Biocompatible Coatings from the Ablation Plasma Produced by the Irradiation of the Hydroxyapatite Target with Powerful Ion Beams

“…In order to make the surface of metal, ceramic, polymeric implants with good biomechanical characteristics bioactive and to provoke the process of osteogenesis of the bone tissue the calcium phosphate (CP) are deposited [1]. The formation of CP coating can be carried out by various methods, among which the following ion-plasma nanotechnological ones are distinguished: the method of high-frequency magnetron sputtering [2], laser ablation method [3], the synthesis of the ablation plasma produced by sputtering the target with powerful ion beam of nanosecond duration (PIB method) [4,5]. PIB method can be applied to form biocoatings with controlled parameters and stoichiometry.…”
