Lubricating additives are essential for enhancing the tribological properties of grease. The development of
low-cost lubricant additives with excellent biodegradability is expected to be the prevailing trend for future
advancements. In this study, biodegradable ultrafine b-tricalcium phosphate (b-TCP) was utilized to
enhance the friction reduction, anti-wear and extreme pressure properties of barium complex greases at
high temperatures. At 150 °C and a load of 150 N, compared to the base grease, the average friction
coefficient (AFC) of barium complex grease with 4.5% b-TCP was reduced by 21.82%. Meanwhile, the
wear volume was reduced by 88.43%. Moreover, the extreme pressure properties of the barium complex
grease were increased by 3.75 times. The lubrication mechanism of b-TCP is the formation of
a protective film of P and Ca compounds on the surface of the friction partner.
