“…This is called the PJD technique. 3,7 Numerous experimental deposition processes have been investigated, including thermal spraying, 8 sputter coating, [9][10][11] pulsed laser ablation, 12 dynamic mixing, 13 dip coating, 14 sol-gel, 15 electrophoretic deposition, 16 biomimetic coating, 17 hot isostatic pressing, 18,19 and aerosol deposition. 20 In most of these processes, the substrate needs to be heated and processed in a chamber under vacuum.…”

This study aimed to create hydroxyapatite (HAp) film by powder jet deposition with manipulating the blasting nozzle above human enamel and to examine the microstructural and mechanical properties of the HAp film and the bonding strength at the interface between the HAp film and the enamel substrate. HAp particles calcinated at 1200°C with an average size of 4.7 μm were used. The HAp particles were mixed with carrier gas (N₂) to form an aerosol flow and was accelerated and blasted from the nozzle onto the enamel substrate at room temperature and atmospheric pressure. To evaluate the microstructure, scanning electron microscope (SEM) images of the surface and cross section of the HAp films and a three-dimensional profile of the HAp films were observed. To evaluate the mechanical properties, the micro-Vickers hardness and the bonding strength of the HAp films to the enamel substrate were measured. The deposition area of the HAp film was over 3 × 4 mm. The average and maximum thickness were about 30 and 40 μm, respectively. No significant difference was observed between the hardness of the HAp film and the enamel (p > 0.05). The bonding strength of the HAp film was the same as the bonding strength between composite resin and enamel. Compared with previous reports, wider and thicker HAp film was created on the enamel substrate successfully. The HAp film, which has same hardness with enamel and same bonding strength to the enamel with composite resin, would be a candidate as dental restorative materials.

“…Pure titanium (Ti) and nowadays, some of the titanium-based alloys are among the most attractive metallic materials for biomedical applications (as implants) due to their non-biodegradability, good mechanical properties as well as their good biocompatibility [2]. However, Ti-based alloys with a high coefficient of friction can lead to formation of wear debris and thus, resulting in inflammatory reaction and loosening of the implant [3,4]. Moreover, the creation of an avascular fibrous tissue leads to inflammatory reactions around these implants [5,6].…”

“…EPD is a cheaper method in comparison with chemical vapor deposition, sol-gel deposition, and sputtering for producing films of a wide range of thickness, from less than 1 mm to more than 100 mm thick [24]. A look at the earlier studies shows that the combination of this method with a subsequent heat treatment process is capable of increasing density and strengthening the ceramic coatings for the corrosion protection and Osseo integration applications [4,5].…”

“…Many techniques have been used to create hydroxyapatite coatings on Ti and its alloy, including plasma spraying [7], pulsed laser deposition [8], ion-beam sputtering [9], electrophoretic deposition [10], radio frequency magnetron sputtering [11], sol-gel [12] and so on. Among these techniques, plasma spraying technique offers an attractive prospect of economy and is the only commercially available method to produce HA coatings [13].…”
