Considerations on Electropolishing of High Speed Steel

The Influence of Hematite on High Speed Continuous Casting of Steel Lubricating Powders: Viscosity and Crystallization

Mold powders used in the continuous casting of steel contain the harmful CaF2 as a main substance developing toxic gases such as SiF4 and HF at elevated temperatures. In this study, three samples of I1, I2 and I3, which contained gypsum free Portland cement clinker with different percentages of Fe2O3 (5.68, 6.83, 8.02 ...

High-Speed PCB Design Considerations

The backplane is the physical interconnection where typically all electrical modules of a system converge. Complex systems rely on the wires, traces, and connectors of the backplane to handle large amounts of data at high speed. The communication between the various backplane modules depends on the inherent electrical characteristics such as impedance, capacitance, and inductance derived from c...

IMPROVING PITTING CORROSION OF 304 STAINLESS STEEL BY ELECTROPOLISHING TECHNIQUE

Several surface modification techniques such as ion implantation, surface laser melting, have been employed to improve pitting corrosion resistance of stainless steel. Electropolishing is a technique in which the surface roughness is eliminated through a selective electrochemical dissolution. The effect of electropolishing on pitting corrosion of 304 stainless steel (SS) was investigated employ...

Superiority of Electropolishing over Chemical Polishing on High Gradients

Electropolishing (EP) offers a smoother surface, and that makes us expect high gradients in superconducting niobium cavities. EP has a little bit complicated procedure and needs annealing to avoid the hydrogen Q-disease. On the other hand, chemical polishing (CP) is easier and cheaper, so widely used in many laboratories. For the conventional field gradients (,z~ 5 MV/m) in storage rings (TRIST...
