Influence of the lubricating medium and its temperature indices on the antifrictional properties of the oils in contact

The evaluation of antifriction indexes in frictional contact with the use of commercial I-40A mineral oil and its composition with the following additives: аnti-wear additive with zinc dithiophosphate content, an anti-scaling additive containing sulfate-phosphate group of surfactants, antifriction additive. It was found that the composition of I-40A oil with an extreme pressure additive effectively lubricates rubbing surfaces, both with increasing load and with increasing rolling speeds, while simultaneously performing a smoothing and polishing effect.
