Abstract : The anti-abrasive additives considered here, dibutyl trichloromethylphosphonate, ethylene dibutylxanthate, and a mixture of chlorinated derivatives, from C25H51Cl to C25H40Cl12, enter into a reaction with iron in the range from 135 to 195 degrees. Metallographic studies of surfaces indicate that such temperatures are developed without seizing under standard limiting conditions of friction. There is some correspondence between the intensity of the exothermic reaction with iron and the anti-abrasive activity in the test on the four-ball machine. The strong anti-abrasive additives after their reaction with iron give no further thermal effects, indicating a change in aggregate state. The absence of any conversions of strong anti-abrasive additives following their reaction with iron indicates that the occurrence of seizing of the surfaces is not connected with the boiling, melting or decomposition of the compound.
