摘要：
A turbine lubricant consisting of (A) alkylated diphenylamine and/or phenylnaphthylamines, and (B) sulfurized olefins and/or sulfurized fatty acids and/or ashless dithiocarbamates and/or tetraalkylthiuram disulfides, with the balance containing (C) base oils characterized by very low sulfur contents ( 90 volume %), and optionally (D) neutral rust inhibitors, show superior oxidative stability and provide adequate corrosion protection and sludge control for turbine oil and R&O oil applications.
