摘　　要：利用四球试验机考察了烷基结构对硫磷酸镉添加剂的极压抗磨性能的影响。结果表明:在一般或较低的负荷下,烷基碳数在3～8之间时,硫磷酸镉化合物有较好的极压抗磨作用,在较高负荷下,随着烷基碳原子数的增加,其抗磨性能、承载能力逐渐减弱,而且,所含烷基碳原子连接方式不同,对其抗磨性能也有较大影响。The effect of the alkyl carbon structure of Cadmium Dialkyldithiophosphate additive on its EP and antiwear properties is investigated by four-ball tester.The results show that,while the carbon number in alkyl group is in a range of 3 to 8,the compound exhibits good EP and antiwear properties under the general or lower load;Antiwear and load-carrying abilities decrease with the increase of carbon number in alkyl group under the higher load.In addition,the alkyl construction has obvious effect on the antiwear property of the compound.
