Micro- and nano-testing of calcium phosphate coatings produced by pulsed laser deposition

Calcium Hydroxyapatite Thin Films on Titanium Substrates Prepared by Ultrasonic Spray Pyrolysis

“…[1][2][3][4][5][6][7][8][9] Such composites are widely used, because they have a capability to integrate directly into bone tissues through the processes of resorption and/or the processes of formation of a new bone on the surface of implant covered by calcium hydroxyapatite. [10][11][12][14][15][16] A variety of methods [17][18][19][20][21][22][23][24][25][26][27] can be used for the synthesis of calcium hydroxyapatite films, such as electrophoretic deposition, 17) electrocrystallization, 18) plasma spray deposition, 19,20) flame spray deposition, 19) magnetic field spattering, 21) deposition by aging in fluids like SBF fluids, 14) ion beam spattering, 22,23) laser beam spattering, 24) electron beam evaporation, 25) sol-gel, 26) aerosol-gel 27) and hydrothermal synthesis. 8,13) Most of these methods are expensive vacuumbased techniques, with problems related to the film homogeneity, require batch processing and usually high-vapourpressure chemicals or high purity targets as starting materials.…”

Application of fluoridated hydroxyapatite thin film coatings using KrF pulsed laser deposition

“…The PLD coatings examined in this study were produced at room temperature to avoid titanium oxidation. The amorphous HA coatings applied using PLD were produced by maintaining the substrate at 290°C, while the crystalline coatings were obtained at 460°C 23) . The degree and rate of recrystallization were time-and temperature-dependent, with effective recovery of the crystalline structure occurring between 500 and 700°C 24) .…”

Nanofeatured Titanium Surfaces for Dental Implantology: Biological Effects, Biocompatibility, and Safety

“…Coating with hydroxyapatite layers can also be obtained through laser treatments, which increases the bond strength between the coating and the substrate [110]. This method allows coating a substrate with hydroxyapatite vapor obtained by heating an hydroxyapatite target with laser.…”
