“…Neither the method of airborne-particle abrasion nor the process parameters are standardized; thus they vary considerably from one study to another. 1,[10][11][12][13] Despite numerous attempts to apply various methods of surface treatment to increase the strength of the bond between a ceramic material and the titanium base, the only effective and available method is surface development by airborne-particle abrasion and ensuring a mechanical bond between the 2 materials. Airborne-particle abrasion of a titanium specimen surface results in morphological changes.…”

“…In addition, compressed air was employed to cool the titanium substrate and maintain its temperature at approximately 200°C in the whole spraying period, decreasing the formation of the non-adhesive oxide layer, which was recognized as the main reason leading to the low bond strength between zirconia coating and titanium substrate in traditional technology. 10 Compared with previous studies 18,19 that employed the plasma spray technique and zirconia particles to prepare zirconia coating on the titanium substrate, it could be concluded that plasma spray parameters, category of zirconia particles, and coating thickness were all closely related to coating quality and bond strength. In this study, optimized plasma spray parameters were employed, including increased voltage and powder feed rate and decreased current and spray distance.…”

“…9 To combine good toughness of titanium with excellent surface properties of zirconia, the zirconia coating was applied on titanium abutment. However, titanium is easily oxidized, and the non-adhesive TiO 2 layer would decrease the bond strength between zirconia coating and titanium abutment, 10 which impeded the clinical application of zirconia-coated abutment.…”

The aim of this study was to evaluate the clinical performance and reliability of plasma sprayed nanostructured zirconia (NSZ) coating. MATERIALS AND METHODS. This study consisted of three areas of analysis: (1) Mechanical property: surface roughness of NSZ coating and bond strength between NSZ coating and titanium specimens were measured, and the microstructure of bonding interface was also observed by scanning election microscope (SEM). (2) Biocompatibility: hemolysis tests, cell proliferation tests, and rat subcutaneous implant test were conducted to evaluate the biocompatibility of NSZ coating. (3) Mechanical compatibility: fracture and artificial aging tests were performed to measure the mechanical compatibility of NSZcoated titanium abutments. RESULTS. In the mechanical study, 400 µm thick NSZ coatings had the highest bond strength (71.22 ± 1.02 MPa), and a compact transition layer could be observed. In addition, NSZ coating showed excellent biocompatibility in both hemolysis tests and cell proliferation tests. In subcutaneous implant test, NSZcoated plates showed similar inflammation elimination and fibrous tissue formation processes with that of titanium specimens. Regarding fatigue tests, all NSZ-coated abutments survived in the five-year fatigue test and showed sufficient fracture strength (407.65-663.7 N) for incisor teeth. CONCLUSION. In this study, the plasmasprayed NSZ-coated titanium abutments presented sufficient fracture strength and biocompatibility, and it was demonstrated that plasma spray was a reliable method to prepare high-quality zirconia coating.

“…Moreover recent studies found that a coating of ZrO 2 -CaO (95%-5wt.%) as a bioactive material facilitates new bone formation, that is, accelerates the process of osteoconductivity [5]. The CaO-ZrO 2 coating in combination with the NiMoAl bond coating is used for deposition with the plasma process, on Ti substrate surfaces before binding of titanium-porcelain for restoration of teeth in dentistry [6]. The bond layer improves adhesion between the substrate and the top ceramic layer.…”

ZrO 2 5CaO is a versatile class of material that can be sintered or plasma spray deposited in combination with other materials on the implant substrate. Due to brittleness the organic ceramic hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 -(HA) is not suitable for use as a separate material in the process of making implants. In order to improve the mechanical characteristics and osteoconductivity, to HA ceramics added are dual systems of oxide solid solutions, of which one is also ZrO 2 5CaO. Ceramics ZrO 2 -CaO(95%-5%) as a biomaterial facilitates osteoconductivity in new bone formation around the implant. This paper represents the need to develop a system of ZrO 2 5CaO/NiCrAl coatings that will with their mechanical and structural characteristics find application on implant parts. In this context, using the atmospheric plasma spray process deposited were the ZrO 2 5CaO/NiCrAl coatings system on stainless steel substrates X15Cr13 (EN 1.4024). Analysis of the morphology of the powder particles and the surface of the ZrO 2 5CaO coatings was carried out on the SEM. The microstructure of the layers of the coatings system was analyzed on the OM. Mechanical properties of the coating were determined by examining the microhardness using the HV 0.3 method and bond strength by tensile testing according to the standard (ASTMC633-1).
