| 摘 要： | 用MRS-10J四球摩擦磨损试验机考察了N68基础油和添加了自修复纳米铜润滑添加剂NT1的N68NT1的摩擦学性能,用扫描电子显微镜（SEM）、x射线能量色谱仪（EDS）分析了钢球表面的磨斑形貌和组成,同时初步分析了纳米铜润滑添加剂的润滑机理.结果表明：自修复纳米铜润滑油添加剂NT1能显著改善N68基础油的摩擦学性能;在载荷为296 N、392 N、490 N,试验时间为30 min的试验条件下,摩擦副的摩擦因数同基础油的相比分别下降了33.8%、39.4%和55.5%;钢球的磨斑直径分别下降了46.5%、45.6%和32.5%;同N68相比,N68NT1的pB值提高了33.3%;这可能同摩擦过程中钢球表面上沉积膜的协同作用有关.

| Abstract: | The tribological characteristics of the base oil N68 and N68NT1 added 4% self-repairing nanocopper lubricant additive NT1 were investigated by MJ-100 four-ball friction and wear tester;the worn spot of steel ball surface and its constitute were respectively analyzed with Scan Electron Microscope(SEM) and Energy Disperse Spectrum(EDS);and the lubricating mechanism of self-repairing nanocopper lubricant additive on the steel/steel friction pairs was discussed.As the results,self-repairing nanocopper lubricant additive NT1 contributes to significantly increasing the anti-wear ability and load-carrying capacity of the base oil N68;the friction coefficients of steel ball/steel ball under lubricated by N68NT1 decrease respectively 33.8%,39.4% and 55.5% compared with that of N68 under load of 296 N,392 N and 490 N;the diameter of worn spot of steel ball decrease of 46.5%,45.6% and 32.5% respectively.Meanwhile,the p_B value of N68NT1 is improved 33.3% compared with that of N68.This may be attributed to the synergetic effect of sediments on the worn steel surface. |
