摘　　要： 本文对传统的润滑油抗磨添加剂(S型、P型、S-P型)和自制的有机硼抗磨剂与常用摩擦副材料(钢、铜、铸铁)在Falex-6型多功能摩擦磨损试验机上进行了配伍性研究,测得了4种抗磨剂与6对摩擦副配合时的P-V图。作者指出,二烷基二硫代磷酸锌(ZDDP)和有机硼抗磨剂对摩擦副材料的选择性不大,特别是有机硼对铜-钢摩擦副显示出较好的减摩抗磨性能;P剂有利于铜-钢和铸铁-钢摩擦副的润滑;S剂和ZDDP更适合于钢-钢摩擦副的润滑。本文还应用X-射线光电子能谱仪(XPS)相扫描俄歇微探针仪(AES)表面分析技术对典型试件表面膜的化学结构进行了分析。 The matching tests between the conventional S,P,S-P-con-taining anti-wear (AW) additives, a newly synthesized organo-boron anti-wear agent and the commonly used tribological materials, such as steel, copper and cast iron, on Falex tester have been carried out in this paper. The P-V (load-velocity) diagrams for four kinds of AW agents matching with six pairs of friction couples were determined. The results of P-V diagram suggested that ZDDP and the organo-boron AW agent shows the weak selectivity on tribological materials. The P-V diagrams also demonstrate that the organo-boron AW agent exhibits fine AW properties when it is matched with copper-steel friction couple, the P-containing AW agent is suitable for the lubrication of copper-steel and cast iron-steel friction couples, whereas the S-containing AW agent and ZDDP are more suited to the lubrication of steel-steel friction couple. It has been found that the P-V diagrams with and without AW agents exhibit distinct discrepancies. No overlap between the first and the second transitional curves has been observed except for the P-V diagram of the S-containing AW agent vs copper-steel friction couple. It suggests that the boundary lubrication (BL) can still exist at high operating velocities due to the formation of BL films on the surfaces of friction couples. Typical matching mechanisms between the S-containing AW agent, the organo-boron AW agent and friction couples were examined and ana- lyzed by means of surface analysis techniques such as Auger Electron Spectroscopy (AES) and X-ray Photoelectron Spectroscopy (XPS). It has been suggested that the S-containing AW agent reacts chemically with the steel surface to produce iron sulfate and iron sulfide films, thus protecting the steel surface from being worn; on the other hand, the Cu2S film with bad toughness, formed by the reaction between S-containing AW agent and copper surface can be easily erased from the copper substrate, resulting in bad AW properties. Additionally, the organo-boron AW agen
