Fabrication of Macrochannelled-Hydroxyapatite Bioceramic by a Coextrusion Process
A coextrusion process was used to fabricate macrochannelled hydroxyapatite (HA). To improve the powder characteristics, the HA powder was calcined at 900°C in air for 1 h. A feedrod composed of HA (shell) and carbon black (core) was coextruded at 120°C through a symmetric 8:1 square reduction die. After the first coextrusion, the individual pieces were bundled, warm-pressed, and then coextruded...
متن کاملBioceramic Scaffolds Fabrication by Rapid Prototyping Technology
This paper describes a rapid prototyping (RP) technology for forming a hydroxyapatite (HA) bone scaffold model. The HA powder and a silica sol are mixed into bioceramic slurry form under a suitable viscosity. The HA particles are embedded in the solidified silica matrix to form green parts via a wide range of process parameters after processing by selective laser sintering (SLS). The results in...
متن کاملNonwoven Microfilters Produced by a Novel Melt Coextrusion Process
Fibrous filters were fabricated using a novel melt co-extrusion and two-dimensional multiplication technology combined with a high pressure water jet delamination technique. The filters made from polypropylene (PP) / polyamide 6 (PA6) system exhibited micro to nano scale fibers having uniform fiber distribution and superior mechanical properties. Effects of film draw ratio upon co-extrusion on ...

متن کاملCrystallographic texture in pulsed laser deposited hydroxyapatite bioceramic coatings.
The orientation texture of pulsed laser deposited hydroxyapatite coatings was studied by X-ray diffraction techniques. Increasing the laser energy density of the KrF excimer laser used in the deposition process from 5 to 7 J/cm(2) increases the tendency for the c-axes of the hydroxyapatite grains to be aligned perpendicular to the substrate. This preferred orientation is most pronounced when th...
