    Influence of nature of dispersed phase on antiwear properties of high temperature greases
    (Publishing House of Lviv Polytechnic National University, 2007) Zhelezny, Leonid; Kobylyansky, Yevgen; Mishchuk, Oleg
    Вивчались протизношувальні властивості сучасних високотемпературних мастил моделюванням на машинах тертя при різних температурах та навантаженнях. Встановлена та пояснена різниця у трибологічних характеристиках мастил в залежності від природи їх загусника. Максимальні протизношувальні властивості виявлено у звичайних комплексних і комплексних надлужних саліцилатних, сульфонатних та фенолятних кальцієвих мастилах. Antiwear properties of modern high temperature greases have been studied by simulating various temperature and load conditions on friction machines. Differences in tribological characteristics of greases depending on the nature of their thickeners were determined and explained. Maximumantiwear propertieswere revealed in conventional complex and overbased complex calcium salicylate, sulfonate and phenolate greases.
