Lab-scale chromium electrowinning in a diaphragm-type cell: effect of anode material and the head between the catholyte and anolyte levels (Δh)

Cüneyt Arslan, Sebahattin Gürmen, Fatma Arslan, Ayşe Gamze Onuk Elçin

Abstract: Turkey has a 6% share in the world of chromite mining and ferrochromium is the most important product in exports. The electrowinning of chromium metal follows the dissolution of chromium from chromite or high-carbon ferrochrome after its separation from gangue and metallic impurities. Although ferrochrome was found to be th [...] Read more.

Optical Surface Plasmon Resonance Monitoring in a High Salinity Environment for Long Duration Sensing Applications

Christopher Lavers, Alistair Cree, David Jenkins, Nasih Salah, Matthew Findlay, Ian Hooper

Abstract: Optical sensing modes such as Surface Plasmon Resonance (SPR) are here applied to the detection surface induced processes and surface corrosion. Our recent studies have investigated the noble metals: silver, copper and gold. We present here results for silver sputter deposited films, with a sputter deposited chromium adhesi [...] Read more.

Influence of Nb, V and Ta on the Microstructure of Ni-hard type Cast Iron for Hot Steel Strip Mills

Sergio Villanueva B., Ishikawa S., Yamamoto Kaoru, Miyahara Hirofumi, Ogi Keisaku

Abstract: Typical Ni-hard type cast iron for hot strip milling rolls contains 3.37%C, 0.90% Si, 4.26%Ni, 1.87% Cr, and 0.55% Mo to crystallize a large amount of ledeburite and a small amount of graphite to achieve a good performance in hot milling of steel strip. Nb, Ta and V up to 2.0 mass % were added to the cast iron to distribute [...] Read more.
