PROTECTIVE CAPACITY OF AVIATION OILS AFTER OPERATION AND STORAGE

The anticorrosion capacity of aviation oils was tested after their ope ration and storage. The mechanism of its variation was proposed for B- 3V, IPM-10 and MS-8P operating oils, These oils provide the maximum pr otection of CT3 and 30XTCA steels after 200 to 400 hours of operation, The protective capacity of the B-3V oil was revealed to increase duri ng its storage for 4 years in an engine, and that of the MS-8rk power- preservation oil was up to 100 h of operation time. It was ascertained that the MS-8rk oil does not lose its protective capacity on being st ored in standard containers for up to 10 years.
