摘　　要：为了研究不同纳米添加剂的减磨抗磨性能,利用油酸(OA)分别对纳米Sm_(2)O_(3),BN和Si_(3)N_(4)进行修饰,然后分散进500SN基础油中,观察其分散稳定性;利用往复式摩擦磨损试验机进行摩擦磨损试验,分析不同纳米添加剂润滑油的摩擦性能与试块磨斑表面形貌。结果表明:纳米添加剂可以起到减摩效果,相较于其他种类的纳米润滑油,纳米Sm_(2)O_(3)浊液的减摩特性较好。在#45钢试块上进行摩擦磨损试验时,试块在纳米Sm_(2)O_(3)润滑油浊液作为润滑介质时的摩擦系数相对于润滑介质为500SN基础油时下降34.55%;而当润滑介质为纳米Sm_(2)O_(3)油液时,纳米Sm_(2)O_(3)的浊液抗磨效果最佳。综上得出结论,纳米Sm_(2)O_(3),BN和Si_(3)N_(4)三种材料中,纳米Sm_(2)O_(3)作为润滑油添加剂减摩抗磨性能最优。In order to investigate the antifriction and anti-wear properties of different nano additives,this study modifies nano Sm_(2)O_(3),BN and Si_(3)N_(4)with oleic acid(OA),and then dispersed them into 500SN base oil to observe the dispersion stability.The friction and wear tests are carried out on reciprocating friction and wear tester to analyze the friction performance of lubricating oils with different nano additives and the surface morphology of wear scars.The results show that nano additives can play a role in reducing friction,among which the Sm_(2)O_(3)turbidity has better friction reduction characteristics,compared with other types of nano lubricants.When the friction and wear test is carried out on the 45 steel test block,the friction coefficient of the test block with Sm_(2)O_(3)nano lubricating oil as the lubricating medium is reduced by 34.55%,compared with that when 500SN base oil is used as the lubricating medium.When the lubrication medium is nano-Sm_(2)O_(3)oil,the friction reduction effect of turbidity in nano-Sm_(2)O_(3)oil is the best.The conclusion is that among the three materials of nano-Sm_(2)O_(3),BN and Si_(3)N_(4),nano-Sm_(2)O_(3)has the best antifriction and anti-wear performance as a lubricant additive.
