Proc. 1555, 75 (2013); 10.1063/1.4820997Influence of spraying parameter on performance of La0.6Sr0.4Co0.2Fe0.8O3 films for IT-SOFCs AIP Conf.Influence of deposition temperature, solvent, and solute concentration on the deposition mechanisms and final structure of mercury iodide fabricated using the spray pyrolysis technique Abstract: The plasma sprayed hydroxyapatite (HA) coatings are used on metallic implants to enhance the bonding between the implant and bone in human body. The coating process was implemented at different spraying power for each spraying condition. The coatings formed from a rapid solidification of molten and partly molten particles that impact on the surface of substrate at high velocity and high temperature. The study was concentrated on different spraying power that is between 23 to 31kW. The effect of different power on the coatings microstructure was investigated using scanning electron microscope (SEM) and phase composition was evaluated using X-ray diffraction (XRD) analysis. The coatings surface morphology showed distribution of molten, partially melted particles and some micro-cracks. The produced coatings were found to be porous as observed from the crosssectional morphology. The coatings XRD results indicated the presence of crystalline phase of HA and each of the patterns was similar to the initial powder. Regardless of different spraying power, all the coatings were having similar XRD patterns.
