Hydrogen permeability of Pd-Ag membrane modules with porous stainless steel substrates
Palladium-based membranes are attractive for their nearly perfect permselectivity to hydrogen. Membrane modules, consisting of a membrane foil, porous stainless steel substrate, test frame and flange were assembled and tested in an electrically heated vessel. Instantaneous hydrogen permeation flux was measured. Influences of operation conditions on the membrane performance were examined. Micros...
متن کاملPreparation of Nanohydroxyapatite-Carbon Nanotube Composite Coatings on 316L Stainless Steel Using Electrophoretic Deposition
Nanohydroxyapatite-carbon nanotube composite coatings were deposited via electrophoretic deposition (EPD). AISI 316L stainless steel and ethanol were used as substrate and dispersing medium, respectively. 5%wt carbon nanotube (CNT) was used as reinforcing phase. Uniform and macrocrack-free coatings were obtained both for hydroxyapatite (HA) and HA-5%wt CNT coatings. Scanning electron micros...

Preparation of Porous Stainless Steel Hollow-Fibers through Multi-Modal Particle Size Sintering towards Pore Engineering
The sintering of metal powders is an efficient and versatile technique to fabricate porous metal elements such as filters, diffusers, and membranes. Neck formation between particles is, however, critical to tune the porosity and optimize mass transfer in order to minimize the densification process. In this work, macro-porous stainless steel (SS) hollow-fibers (HFs) were fabricated by the extrus...
متن کاملIn situ observation of pitting of stainless steel by XAFS.
An in situ observation technique by XAFS (X-ray Absorption Fine Structures) has been developed for observation of metal corrosion. XAFS spectra were obtained with a special electrochemical cell to elucidate pitting: change of concentrations and structures of ions near the interface of solution and metal. It has been successfully shown that the concentrations of Cr and Br are linearly dependent ...
