【摘要】 合成了粒径约为3nm的二-十六烷基二硫代磷酸(DDP)修饰ZnS纳米粒子和油酸(OA)修饰ZnS纳米粒子,并分别用四球摩擦磨损试验机考察了它们作为润滑油添加剂的摩擦学行为。结果表明,二者都能起到良好的抗磨效果,油酸修饰ZnS纳米粒子作为润滑油添加剂能够明显降低摩擦因数,而DDP修饰ZnS纳米粒子反而使摩擦因数略有升高。更多还原

【Abstract】 Di-hexadecyldithiophosphorate (DDP) capped ZnS nanoparticles and oleic acid (OA) capped ZnS nanoparticles with average diameter of 3 nm were prepared and the tribological behaviour of them as oil additive was investigated using a four-ball wear tester,respectively.Results show that both DDP capped ZnS nanoparticles and OA capped ZnS nanoparticles can remarkably improve the antiwear ability of liquid paraffin,OA capped ZnS nanoparticles exhibit good friction-reducing ability but DDP capped ZnS nanoparticles can not reduce friction.更多还原
