Fabrication of Lotus-Type Porous Aluminum Utilizing Decomposition of Moisture
Lotus-type porous aluminum with cylindrical pores oriented in one direction was fabricated by a casting method utilizing the decomposition of moisture in a vacuum. Hydrogen decomposed from moisture is utilized for cylindrical pores to grow during unidirectional solidification. However, pores are not formed in the case of a casting in hydrogen or argon atmosphere, because hydrogen or argon gas p...
متن کاملEffect of Hydrogen Pressure on Moisture-Based Fabrication of Lotus-Type Porous Nickel
Lotus-type porous nickel, which has long straight pores aligned in one direction, was fabricated by utilizing moisture during unidirectional solidification in argon atmosphere. We studied the effect of the quantity of hydrogen in the atmosphere on the fabrication of lotus-type porous nickel. Adding hydrogen in the atmosphere, it was expected that the porosity of the lotus-type porous nickel wit...
متن کاملFabrication, properties, and applications of porous metals with directional pores
Lotus-type porous metals with aligned long cylindrical pores are fabricated by unidirectional solidification from the melt with a dissolved gas such as hydrogen, nitrogen, or oxygen. The gas atoms can be dissolved into the melt via a pressurized gas atmosphere or thermal decomposition of gaseous compounds. Three types of solidification techniques have been developed: mold casting, continuous zo...
متن کاملFabrication of p-Type Nano-porous Silicon Prepared by Electrochemical Etching Technique in HF-Ethanol and HF-Ethanol-H2O Solutions
Nano-porous silicon were simply prepared from p-type single crystalline silicon wafer by electrochemical etching technique via exerting constant current density in two different HF-Ethanol and HF-Ethanol-H2O solutions. The mesoporous silicon layers were characterized by field emission scanning electron microscopy and scanning electron microscopy. The results demonstrate that the width of nano-p...
متن کاملFabrication of fixed partial dentures using functionally generated path technique and double casting.
Harmonious occlusion is a critical requirement for successful oral rehabilitation. Conventional techniques of construction have been unsuccessful in producing a prosthesis that can be inserted without intraoral occlusal adjustment. This article discusses the use of functionally generated path technique with double casting to fabricate fixed partial dentures. The merits of this approach and the ...
