Abstract : In support of a research programme to investigate surface distress of spiral bevel gears used in helicopter transmission systems, as complete a survey as possible was made of published work on lubricants incorporating load-carrying additives, paying special regard to those containing phosphorus compounds. The introduction to the review mentions types of lubrication and additives in general. Papers dealing with compounds having extreme pressure and antiwear additives are then considered and phosphorus containing materials are detailed. The main part of the review summarizes the papers. A more critical appraisal is made at the end of this section and finally conclusions reached from the study are given.
