Evaluation of microstructure and electrochemical behavior of dual-layer NiCrAlY/mullite plasma sprayed coating on high silicon cast iron alloy

Hydroxyapatite Consolidated by Zirconia: Applications for Dental Implant

“…Coatings can be porous or dense depending on their production procedure with a thickness ranging from 1 to 100 μm. Various ceramic coating methods in dental implants include sol-gel [54][55][56], hot isostatic pressing (HIP), plasma spraying [57][58][59], electrophoretic deposition [60], sputter-deposition and pulsed laser deposition [61].…”

Evaluation of Corrosion Resistance of Bi-layered Plasma-sprayed Coating on Titanium Implants

“…The nano powders do not have the ability to spray by plasma spraying due to the lack of adequate fluidity. Some portion of the nanoparticles should be melted because mechanical behavior of the coating is strongly related to melting degree of sprayed particles [35].…”

“…It has been reported that rapid solidification can reduce the crystallinity degree of HA coatings [27,28]. Also, most investigations were done to determine in vitro and in vivo properties of plasmasprayed HA coating [29][30][31][32][33][34][35][36]. Vu et al [29] presented that the superior bone information of ZnSiAg-HA coatings when they were implanted in 18 male Sprague-Dawley rats.…”

Synthesis of TiB2-Ni3B nanocomposite coating by DC magnetron sputtering for corrosion-erosion protection

“…Polarization potentials are generally time-dependent and represent the evolution of the corrosion reactions [36]; however, the coating's cathodic and anodic polarization curves after 8, 16, and 24 h of exposition were similar. It could be said that corresponding with the same electrochemical reaction independent of the exposition time due to the chemical stability of the coating; in such a way that in each time interval, the curves overlapped as if the same corrosion reaction is repeated without progressive material degradation [37,38].…”
