Abstract: Based on the experimental methods abroad, a simulating evaluation method for axletree corrosion property of synthetic aircraft lubricants was established with two kinds of synthetic aircraft lubricants as standard. The axletree corrosion properties of the two standard lubricants and seven kinds of synthetic aircraft lubricant samples at home and abroad were evaluated. The results show that the method has favorable repeatability and distinguishability and those two kinds of standard lubricants can simply and unfailingly ensure the efficiency of the experiment. Through the evaluating method, the axletree corrosion property of synthetic aircraft lubricants can be distinguished.
