SURVEY OF THE LITERATURE ON ANTIOXIDANTS AND ANTICORROSION ADDITIVES FOR LUBRICANTS AT ELEVATED TEMPERATURES

摘要

The literature was surveyed on oxidation and corrosion inhibitors in various media at elevated temperatures. Particular attention was given to phenothiazine types of additives and to lubricants of the synthetic-base type. Media, such as rubber, were included where the effects noted might have analogies in synthetic base lubricants. The literature revealed very few anti¬oxidant or anticorrosion combinations for synthetic base lubricants at extreme temperatures. The survey covered the period 1916 to Juno 1952. There were very few significant literature references prior to 1916. The survey can be readily brought up-to-date when the 1952 subject index of Chemical Abstracts becomes available. Approximately 2500 abstracts of research reports, patents, reviews, articles, etc. were recorded on McBee Keysort Punch Cards of special design. Three punch card indices were devised covering approximately 100 entries, each entry being designated by a four-letter code word. A novel card-needling box was designed and constructed to facilitate use of the card file.
