A Study on the Wear Performances of Dibutyl 3,5-di-t-Butyl 4-Hydroxy Benzyl Phosphonate under Sliding and Rolling Contacts
미끄럼 및 구름접촉하에서 Dibutyl 3,5-di-t-Butyl 4-Hydroxy Benzyl Phosphonate의 마모성는에 관한 연구
Abstract
Wear performances for dibutyl 3,5-di-t-butyl 4-hydroxy benzyl phosphonate (DBP) were invesitigated using the four ball test machine under sliding and also rolling contact conditions, and compared with ZDDP. DBP showed excellent antiwear performace compared with ZDDP under severe sliding contact. Also, DBP achieved a longer fatigue life than ZDDP under rolling contact conditions. The surface of the worn balls was observed using an optical microscope, and the wear derbis generated was measured using the Particle Quantifier (PQ).
