During the friction process, the elements in the extreme pressure additive and the metal surface ( Iron or iron oxide) reacts to form an inorganic compound film (extreme pressure film), which is more load-bearing than organic molecular adsorption films and is more stable at high temperatures. Currently, the extreme pressure agents commonly used in lubricating oils are mainly divided into the following: Mizuma: 1.
