Corrosive wear, i.e., wear in which the primary cause is oxidation of the metal surface, is shown to be an important factor in jet fuel lubricity. A literature survey has been made, which indicates considerable confusion and disagreement. Additional hydrocarbons have been evaluated. Most of them give more wear and friction when oxygen and water are present. Indene and 1-methyl naphthalene are exceptions, giving high wear in dry, inert atmospheres. No explanation has been found for these differences. High-temperature tests in the presence of oxygen often give lower wear than tests at lower temperatures. This has been shown to be due to the formation of oxidation products that have good lubricity.
