Titanium carbide is used as an attractive reinforcement to produce particulate metal matrix composites. One of the problems to use this carbide as a reinforcement in copper-based composites is the lack of wetability in Cu-TiC system. This property improves as the C/Ti ratio in carbide decreases. Problems to use this carbide as a reinforcement in copper-based composites is the lack of wetabiity...

To explore the effect of copper content in a copper-doped hydroxyapatite coating (CuHAp) on its antibacterial activity and biocompatibility, layer CuHAp was deposited surface pure Ti using an electrochemical deposition method. An orthogonal experiment used to determine Cu by varying concentration Cu2+ electrolyte. The properties biocompatibility coatings were also evaluated. increased with incr...

Two T-kininogens (TI- and TII-kininogens) found in plasma of Freund's adjuvant-treated rats were purified by several chromatographic procedures. The isolated TI- and TII-kininogens showed different mobilities on polyacrylamide gel electrophoresis in the absence of sodium dodecyl sulfate, but were indistinguishable in the presence of sodium dodecyl sulfate. They were also indistinguishable in am...

Fine particle peening (FPP) using hydroxyapatite (HAp) shot particles was performed to improve the fatigue strength and form a HAp transfer layer on beta titanium alloy (Ti–22V–4Al). The surface microstructures of FPP-treated specimen were characterized scanning electron microscopy, micro-Vickers hardness testing, energy dispersive X-ray spectrometry, diffraction, backscattered diffraction. A w...

background:   after cervical discectomy, autogenetic bone is packed into the cage to increase the rate of :union: between adjacent vertebral bodies, but donor site–related complications can still occur. in this study we evaluate the use   of hydroxyapatite granules as a substitute for autograft for interbody fusion.     methods:   from november 2008 to november 2011, 236 patients participated i...
