LUBRICITY PROPERTIES OF HIGH-TEMPERATURE JET FUELS

Abstract

The Micro-Ryder gear test was evaluated as a possible test device for jet fuels. Scuffing tests generally agreed with earlier wear tests in assessing the effects of fuel composition and operating variables. However, some differences were found: some sulfur compounds reduced scuffing, whereas they had not reduced wear; scuffing is frequently more severe in dry argon than in wet air, whereas in wear tests this was reversed. Water appears to be the important factor reducing scuffing. K-Monel showed some major differences from steel, even stainless steels. Abrasive wear was briefly studied. In the vane pump test, abrasive wear can be the major cause of wear. It is sensitive to the kind and amount of abrasive particles, but no general correlation could be found with particle size, hardness, or crystal structure, or concentration. Oleic acid can eliminate abrasive wear.
