Abstract This paper presents the developed software for processing parameter simulation and optimization of powder bed additive manufacturing by concentrated energy beams. The simulations are realized implementation a normalized diagram analytical model simulating heating layers moving linear heat source. Their is demonstrated electron beam or laser industrial alloys. provide useful reference m...
Detonation-produced hydroxyapatite coatings were studied by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), Raman spectroscopy, and electron paramagnetic resonance (EPR) spectroscopy. The source material for detonation spraying was a B-type carbonated hydroxyapatite powder. The coatings consisted of tetracalcium phosphate and apatite. The ratio depended slightly on the degre...
The objective of this study was to produce well-dispersed nanosized yttria tetragonally stabilized zirconia (Y-TZP) powder in aqueous suspension. The Y-TZP powder was produced by precipitation from homogeneous solution at 2001C under hydrothermal conditions. A homogeneous solution was created through the use of a complexing agent, which subsequently could be used in a dispersion scheme develope...
Mullite and mullite/ZrO2-7wt.%Y2O3 coatings could be thought among the main protective layers for environment barrier coatings (EBCs) to protect Si-based substrates in future gas turbine engines. Considering that feedstock of the compound powder is not commercially available, two powder processing routes Spray Drying (SD) and Flame Spheroidization (FS) were implemented for both types of powders...
This review provides an insight into mechanical properties that are critical to understanding powder processing for tableting. Various parameters that reflect these basic fundamental properties of powder and their evaluation by different techniques are described. Some recent examples in which these techniques are used in drug substance selection, formulation optimization or scale-up are also pr...
