Corrosion of Galvanized Steel in Soils
The results of measurements of the corrosion of galvanized steel and of bare steel and zinc as reference materials after exposure to different soil conditions for a maximum of 13 years are reported. The magnitude and progress of corrosion of galvanized steel as determined by weight loss and pitting is interpreted in terms of the environmental conditions to which the specimens were exposed. From...
متن کاملRu(III)-exchanged FAU-Y zeolite as an efficient heterogeneous catalyst for preparation of oxindoles
Ru(III)-exchanged FAU-Y zeolite was used as an efficient reusable heterogeneous catalyst for preparation of oxindoles from condensation reaction of indoles with isatins under very mild reaction conditions.
متن کاملStudies on defects in galvanized coating on steel wire
Causes for deposition of defective galvanized coating (lumpy deposition of coating during hot dip galvanizing) of carbon-steel wire have been investigated. It is established that the lumpy deposition is caused due to segregation of silicon on the surface of steel wire. Due to this change in composition of the steel at surface, the regions get modified and lie in Sandelin hyper reactive zone. Th...
متن کاملEffects of lanthanum and lanthanum-modified clay on growth, survival and reproduction of Daphnia magna.
The novel lanthanum-modified clay water treatment technology (Phoslock seems very promising in remediation of eutrophied waters. Phoslock is highly efficient in stripping dissolved phosphorous from the water column and in intercepting phosphorous released from the sediments. The active phosphorous-sorbent in Phoslock is the Rare Earth Element lanthanum. A leachate experiment revealed that lanth...
