Novel Ca-Si-Ti-based sphene (CaTiSiO5) ceramics possess excellent chemical stability and cytocompatibility. The aim of this study was to prepare sphene coating on titanium alloy (Ti-6Al-4V) for orthopaedic applications using the plasma spray method. The phase composition, surface and interface microstructure, coating thickness, surface roughness and bonding strength of the plasma-sprayed sphene...

Abstract Besides conventional industrial demands, thermally sprayed coatings are increasingly used for innovative products. Such an application is the additive manufacturing of electrical components in automotive engineering. In particular, heating units currently manufactured by a combination various spray technologies. At present, simpler spraying processes like flame investigated with regard...

A combination of characterization techniques has been used to provide new understanding the complex crystallization behavior as-sprayed amorphous Yb2Si2O7-based air-plasma-sprayed environmental barrier coatings (EBCs). During heat-treatment, initially a mixture metastable ?-Yb2Si2O7 and X1-Yb2SiO5 phases form, along with stable ?-Yb2Si2O7 X2-Yb2SiO5 phases. Eventually transform (major) (minor) ...

Titanium and its alloys are wildly used in industries. Shrouded plasma spray can be considered as a useful technology to produce low oxide containing titanium coatings. In this paper, the effect of shroud spraying on chemical composition thickness coatings were investigated. plasma-sprayed deposited onto mild steel substrates. Air also for comparison under same parameters. Those then studied te...

Nickel chromium (NiCr) powders with different titanium diboride (TiB2) additions (20, 40 and 60 wt %) were prepared with a mechanical alloying method and then sprayed using an air plasma spraying technology. The microstructure and phase composite of the powders and the cross-sections of deposited coatings were analyzed with a scanning electronic microscope and X-ray diffraction. The tribologica...

Abstract Al 2 O 3 –TiO coatings were received by flame sprayed of flexible cord and plasma using powder. Shown higher mechanical tribological properties coating compared coating.

A simple and novel method--in the form of solution spraying--was developed to fabricate biodegradable, porous poly(L-lactic acid) (PLLA) particulates for scaffold. PLLA pellets were dissolved in an organic solvent. Then, 5 % PLLA-dioxane solution was sprayed using an air-assisted atomizer with a nozzle diameter of 2.5 mm at an air flow rate of 15 L/min. After the sprayed solution solidified in ...
