合成了一种新型无硫无磷有机钼油基添加剂N，N-双（2-羟乙基）十二酰胺基钼油（NNDM）。在四球摩擦磨损试验机上考察了其在150 SN基础油中的摩擦学性能，并与ZDDP和MoDTC在边界润滑条件下的摩擦学性能进行了比较。用扫描电镜（SEM）和X射线光电子能谱（XPS）分析了摩擦副表面产生的摩擦膜NNDM。结果表明，NNDM调合油具有优异的承载能力，显著降低了摩擦因数和磨损率，这与NNDM摩擦膜中含有大量的长链烷基酰胺和MoOx有关。(C)2012爱思唯尔有限公司保留所有权利。
A new kind of sulfur- and phosphorus-free organomolybdenum oil-based additive N, N-bis (2-hydroxyethyl)-dodecanamide molybdate (NNDM) was prepared. Its tribological performances as additive in base oil 150SN were examined on a four-ball tester, and compared with those of ZDDP and MoDTC under boundary lubrication condition. The tribofilm NNDM generated on the worn surface was analyzed by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Results showed that NNDM blend oil exhibited excellent load-carrying capacity, significantly reduced friction coefficient and wear rate of worn surface, which could be attributed to high amount of long-chain alkylamide and MoOx in NNDM tribofilm.
