本文以油酸铜为代表,考察了硼酸酯与油溶性铜化合物的复合抗磨性能,发现两者具有良好的协同作用。摩擦表面的SEM、XPS分析表明,二者协同抗磨的机理,主要在于含有缺电子空轨道的硼原子,催化CU~(2+)在外逸电子作用下的摩擦还原反应,在温和的摩擦磨损条件下,摩擦还原的单质铜,沉积在金属表面并与之合金化;在苛刻条件下,沉积铜形成薄膜或呈球状。
In this paper, copper oleate as a representative, studied the anti-wear properties of boric acid ester and oil-soluble copper compounds, found that both have good synergies. The SEM and XPS analysis of the friction surfaces show that the synergistic anti-wear mechanism of the friction surfaces mainly lies in that the boron atoms containing vacancies in the electron-deficient electron orbit are responsible for the catalytic reduction reaction of CU 2+ under the action of external electrons. Under mild friction and wear Under the condition, the friction-reduced elemental copper is deposited on and alloyed with the metal surface; under severe conditions, the deposited copper is formed into a thin film or spherical.
