PROCESS FOR TREATING FRICTIONAL FRICTION SURFACES, SPECIFICALLY DURING LUBRICATION, AND COMPRESSOR SUBJECTED TO SUCH A METHOD

摘要

P THIS PROCESS IS INTRODUCED INTO THE LUBRICATION OIL OF FRICTIONAL SURFACES OF MOBILE PARTS, AT LEAST ONE ADDITIVE ENABLING THE CHEMICAL MODIFICATION OF THE FRICTIONAL SURFACES WITH WHICH IT IS IN CONTACT WHEN THE TEMPERATURE T OF THESE SURFACES REACHES A VALUE T DETERMINED. / P P THE ADDITIVE IS FOR EXAMPLE A METALLIC COMPOUND OF DITHIOPHOSPHATE HAVING THE PROPERTY OF PROGRESSIVELY RELEASING SULFUR AND THE PHOSPHORUS IT CONTAINS, BASED ON THE RISE OF THE TEMPERATURE OF FRICTION SURFACES. , AND CAUSE THE FORMATION OF SULFIDE AND PHOSPHIDE ON THESE SURFACES. / P P APPLICATION: CHEMICAL TREATMENT OF FRICTION SURFACES OF MOBILE PARTS OF A HERMETIC COMPRESSOR. / P
