Dual-Material Electron Beam Selective Melting: Hardware Development and Validation Studies Article

Chao Guo, Wenjun Ge, Feng Lin

Engineering 2015, Volume 1, Issue 1,   Pages 124-130 doi: 10.15302/J-ENG-2015013

Abstract:

Electron beam selective melting (EBSM) is an additive manufacturing technique that directly fabricates three-dimensional parts in a layerwise fashion by using an electron beam to scan and melt metal powder. In recent years, EBSM has been successfully used in the additive manufacturing of a variety of materials. Previous research focused on the EBSM process of a single material. In this study, a novel EBSM process capable of building a gradient structure with dual metal materials was developed, and a powder-supplying method based on vibration was put forward. Two different powders can be supplied individually and then mixed. Two materials were used in this study: Ti6Al4V powder and Ti47Al2Cr2Nb powder. Ti6Al4V has excellent strength and plasticity at room temperature, while Ti47Al2Cr2Nb has excellent performance at high temperature, but is very brittle. A Ti6Al4V/Ti47Al2Cr2Nb gradient material was successfully fabricated by the developed system. The microstructures and chemical compositions were characterized by optical microscopy, scanning microscopy, and electron microprobe analysis. Results showed that the interface thickness was about 300 μm. The interface was free of cracks, and the chemical compositions exhibited a staircase-like change within the interface.

Removal of fluoride from water using titanium-based adsorbents

Zhijian LI, Shubo DENG, Xueying ZHANG, Wei ZHOU, Jun HUANG, Gang YU

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 4,   Pages 414-420 doi: 10.1007/s11783-010-0241-y

Abstract: Three adsorbents including TiO , Ti-Ce, and Ti-La hybrid oxides were prepared to remove fluoride from aqueous solution. The Ti-Ce and Ti-La hybrid adsorbents obtained by the hydrolysis-precipitation method had much higher sorption capacity for fluoride than the TiO adsorbent prepared through hydrolysis. Rare earth (Ce and La) oxides and TiO exhibited a synergistic effect in the hybrid adsorbents for fluoride sorption. The sorption equilibrium of fluoride on the three adsorbents was achieved within 4 h, and the pseudo-second-order model described the sorption kinetics well. The sorption isotherms fitted the Langmuir model well, and the adsorption capacities of fluoride on the Ti-Ce and Ti-La adsorbents were about 9.6 and 15.1 mg·g , respectively, at the equilibrium fluoride concentration of 1.0 mg·L , much higher than the 1.7 mg·g on the TiO . The sorption capacities of fluoride on the three adsorbents decreased significantly when the solution pH increased from 3 to 9.5. The electrostatic interaction played an important role in fluoride removal by the three adsorbents, and Fourier transform infrared (FTIR) analysis indicated that the hydroxyl groups on the adsorbent surface were involved in fluoride adsorption.
