摘要
利用高速环-块摩擦磨损试验机考察了一系列脂肪醇对铝-钢摩擦副的润滑作用,研究了添加剂分子链长和添加量与润滑效果的关系,发现添加剂分子间作用力对其减摩抗磨效果具有决定影响。
The antiwear ability and load carrying capacity of a range of aliphatic alcohols as lubricating additives in liquid paraffin were evaluated using a Timken tester. The effects of additive concentration and chain length were investigated. It has been found that the antiwear ability of aliphatic alcohols for aluminum on steel system is closely related to the concentration and the molecular chain length. The best lubrication and antiwear behaviors are obtained at an additive concentration of 2.22%, 1.30%, and 0.93%, for 1 butanol, 1 octanol, and 1 dodecanol, respectively. The intermolecular force of the additive governs the lubricating function, while the lubrication and wear resistant behaviors of the additives are correlated with their protection chemical corrosion balance on the lubricated metal surface.
