Friction and wear behaviors of aluminum-on-steel under the lubrication of grease containing a complex of lanthanum dialkyldithiocarbamate and phenanthroline

摘要: Abstract A complex of lanthanum dialkyldithiocarbamate and phenanthroline was synthesized, its lubricating antiwear behaviors as an additive in lithium grease were evaluated using a Timken tester with SAE52100 steel ring sliding under A1 2024 block. As comparison, the wear behavior steel-on-steel system lubrication same also investigated test conditions. The protective film formed on rubbed surface aluminum by both XPS AES. Results friction tests indicate that this rare earth possess good ability for aluminum, reduction properties aluminum-on-steel is even superior to system. results AES analyses illustrate prepared La forms containing oxide, sulphide, organic compound sulfur nitrogen aluminum.
