Tribological Properties of Plastic Lubricants Infused with Molybdenum-Containing Additives

The wear and score resistance of different types of plastic lubricants infused with additives based on sulfur-containing molybdenum compounds are studied. It is shown that the tribological properties of all the studied lubricants are improved by infusion with 2-8 wt. % of molybdenum dithiocarbamate and that the additives are most active in the lubricants containing polyurea thickener.
