Abstract : Molybdenum disulfide is oxidized in air under the influence of high temperatures. The oxidation product is molybdenum trioxide. Molybdenum trioxide in the friction zone acts like an abrasive. Molybdenum disulfide does not lose its lubricating properties for long periods of time in air at temperatures up to 300 degrees centigrade. At temperatures above 300 degrees centrigrade, it is effective for a limited period and needs systematic restoration of the lubricant. The stability of molybdenum disulfide lubricating properties is maintained during friction of the surfaces it covers, up to the temperatures in the contact zone, which greatly exceed the temperature of its complete oxidation, because of the short duration of the flash points.
