摘要: A complex of lanthanum and di-(2-ethyl hexyl) phosphate (DEHP) was prepared by an extractive method. The friction wear behaviour this (called LaDEHP) as oil additive evaluated using a four-ball tester. For comparison, the reduction antiwear properties DEHP were also investigated. chemical composition boundary film formed after tests examined X-ray photoelectron spectrometry (XPS). Four-ball showed that LaDEHP effective in reducing well increasing load-carrying capacity. XPS analyses indicate formation iron oxide films.
