Dissimilar Metal Corrosion

Corrosion Performance of Prestressing Strands in Contact with Dissimilar Grouts

To improve the corrosion protection provided to prestressing strands, anti-bleed grouts are used to fill voids in post-tensioning ducts that result from bleeding and shrinkage of older portland cement grouts. Environmental differences caused by exposing the strands to dissimilar grouts, however, have the potential to cause rapid corrosion. Portland cement grout, gypsum grout, and four commercia...

Volatile Inhibitors of Metal Corrosion. I. Vaporization

This paper presents an analytical review of data on the interaction of volatile corrosion inhibitors with the atmosphere, vaporization processes, methods of experimental and computational estimation of the vapor pressure of organic compounds, and effects of vaporization conditions and compound structure on vapor pressure.

Prediction of Metal Corrosion by Neural Networks

Z. Jančíková, O Zimný, P. Koštial, Faculty of Metallurgy and Material Engineering, VŠB – Technical University of Ostrava, Czech Republic The contribution deals with the use of artifi cial neural networks for prediction of steel atmospheric corrosion. Atmospheric corrosion of metal materials exposed under atmospheric conditions depends on various factors such as local temperature, relative humid...

Investigation of dissimilar metal welds by energy-resolved neutron imaging

A nondestructive study of the internal structure and compositional gradient of dissimilar metal-alloy welds through energy-resolved neutron imaging is described in this paper. The ability of neutrons to penetrate thick metal objects (up to several cm) provides a unique possibility to examine samples which are opaque to other conventional techniques. The presence of Bragg edges in the measured n...
