3、arStructure是片狀結(jié)構(gòu)或紐織。最終我所確定的題目為:《納米級(jí)片狀結(jié)構(gòu)的膨脹石墨填充PTFE復(fù)合材料的摩擦磨損性能》。從題hl中,基本可以了解作者的研究重點(diǎn):將納米級(jí)片狀結(jié)構(gòu)的膨脹石墨添加到以聚四氟乙烯(PTFE)為基礎(chǔ)的復(fù)合材料中,從而研究分析該復(fù)合材料的摩擦性能。Keywords關(guān)鍵詞木文的關(guān)鍵詞:PTFE/nano-EGcomposite,frictionandwear,transferfilm,CLSM,FESEM.其屮各詞的含義:PTFE/nano-EGcomposite納米級(jí)膨脹石墨聚四氟乙烯基復(fù)合材料;frictionandwear擦磨損;tnmsferfilm轉(zhuǎn)移膜;
4、CLSM激光共焦掃描顯微鏡;FESEM場(chǎng)發(fā)射掃描電子顯微鏡。因此,本文的研究方向是PTFE基復(fù)合材料。所借助的實(shí)驗(yàn)設(shè)備為激光共焦掃描顯微鏡和場(chǎng)發(fā)射掃描電了顯微鏡,丿IJ來(lái)觀察微觀的材料特性。所研究的內(nèi)容為納米級(jí)膨脹石墨PTFE基復(fù)合材料的磨損機(jī)理和對(duì)偶而上轉(zhuǎn)移膜的研究。Abstract摘要Thispaperprovidesapolytetrafluoroethylene(PTFE)/nano-EGsolidself-lubricatingcompositethatexhibitsverylowfrictioncoefficientandwearrate.Inpresentstudy,thei
