| 摘 要： | 将所合成的乙二胺缩水杨醛Schiff碱铜（Ⅱ）络合物和甘油-聚乙烯微胶囊与超高分子量聚乙烯（UHMWPE）共混制备出改性UHMWPE材料，利用销-盘式摩擦磨损试验机评价Schiff碱铜（Ⅱ）络合物和甘油．聚乙烯微胶囊改性UHMWPE／GCr15钢配副在高速干摩擦条件下的摩擦磨损性能，利用扫描电子显微镜观察其磨损表面形貌，采用电子能谱仪分析磨损表面的主要元素组成并探讨其磨损机理．结果表明，由于其独特的自身选择性转移效应使得耐磨性提高，在高速干摩擦条件下没有严重的粘着磨损．

| Abstract: | A new kind of modified UHMWPE with the synthesized Cu(II) chelate of bissalicylaldehyde-ethylenediamine(Schiff Base Copper(II) Complex) and the synthesized glycerine microcapsules with polyethylene wall was prepared.Friction and wear properties of the modified UHMWPE against GCr15 steel under dry friction condition and at a high sliding velocity were studied with a pin-on-disk tester.In order to investigate wear mechanism of the modified UHMWPE,topographies of worn surface were observed by SEM and main elements of worn surface were analyzed by EDAX.The results show that wear resistance of the modified UHMWPE was improved obviously by comparison with that of pure UHMWPE due to its special self-selective transferring effect.Serious adhesive wear processes,which appeared usually in rubbing pairs of steel with various polymers under dry friction conditions,were never done in the modified UHMWPE / steel pair. |
