Study of the comportment of fatty acids and mineral oils on the surface of steel pieces during galvanization

This study shows that vegetable oil like linseed oil can be used as flux in hot-dip galvanization. The natural fatty acids contained in them seem to be able to play similar role of chloride flux usually used. Moreover, it is also possible to use a mineral oil with an added acid function. “Pure” mineral oil well protects the steel from corrosion but leads to a very bad result in galvanization. When an acid function is added to this mineral oil, for example by an addition of hydrochloric acid, the result in galvanization is very good. The coat thickness and the inter-metallic composition depend not on the nature of the flux.     

Influence of solid contaminants in oil on wear characteristics of nano-Al2O3／Ni composite coating

Solid conlaminants in Iubrication system will cause severe wear of sliding components. In order 1o improve the wear resistance of the material in oil containing solid contaminants, the brush plated nano-Al2O3/Ni composite coating was prepared and the influence of the sand content and sand size on the tribological property of the coating in oil containing solid contaminants was tested with ball-on-disc tester. The results show that the wear volume increases with increasing the sand content and sand size, and the wear resistance of the composite coating is 20% higher than that of the high-speed plain nickel coating. The main wear mechanisms of the coatings are abrasive wear and adhesive wear. And due to the nano-particle strengthening effect, the wear resistance of the composite coating is improved.

Processing of tailings in Canadian oil sands industry

Vast amounts of tailings are produced daily in bitumen extraction from the Athabasca oil sands.The coarse sand from the tailings stream is used to build dykes around the containment basin.The run-off slurry arrives at the water‘s edge in the tailings pond at a solids concentration of about 3%-8% by mass.Settling of the solids takes place“felatively fast”,over several days,creating a “free water zone” that contains little solids.When the fine mineral solids concentration has reached about 15% by mass,the suspension develops non-Newtonian properties.After2-3years,the suspension concentration reaches a value of about 30% by mass at which the settling rate becomes extremely slow.Methods to hadle the already created tailings ponds and new approaches to eliminate the creation of new ones will be discussed both from the industrial and fundamental prospective.
