Externet Posted April 27, 2008 Share Posted April 27, 2008 Hi. Can the surface oxide layer be permanently removed if a piece of the metal is scraped while submerged in oil -and kept in it- ? Link to comment Share on other sites More sharing options...
YT2095 Posted April 27, 2008 Share Posted April 27, 2008 yes, IF the oil is free of water and oxygen, but that`s harder to do than it sounds. Link to comment Share on other sites More sharing options...
John Cuthber Posted April 27, 2008 Share Posted April 27, 2008 No, because Al reacts with water to give the oxide and hydrogen. Link to comment Share on other sites More sharing options...
Externet Posted April 27, 2008 Author Share Posted April 27, 2008 Thanks for the responses... Do you know of any oil type with a low amount of reacting oxygen / moisture that you can recommend, please? or process to de-oxygenate it ? Heating it up to evaporate moisture ?

YT2095 Posted April 28, 2008 Share Posted April 28, 2008 I`d probably opt for a reasonably long chain alkane (reagent grade) anywhere between Decane and Paraffin. and add pure calcium metal to it, and just leave it stand in a desiccator for a few days.
