<p>The process consists in introducing into the oil for lubricating the rubbing surfaces of moving parts, at least one additive ensuring the chemical modification of the rubbing surfaces with which it is in contact when the temperature T of these surfaces reaches a determined value To. The additive is, for example, a dithiophosphate metal compound which has the property of progressively releasing the sulphur and the phosphorus which it contains, as a function of the rise in the temperature of the rubbing surfaces, and causing the formation of sulphide and phosphide on these surfaces. Application: Chemical treatment of the rubbing surfaces of moving parts of a hermetic compressor. <IMAGE></p> |
