双水杨醛缩1,6-己二胺Schiff碱铜配合物改性UHMWPE新型耐磨材料的研究
Study on a new wear resistant material of UHMWPE modified with Cu ( Ⅱ ) chelate of bissalicylaldehyde-1,6-hexanediamine
摘要
Abstract
Friction and wear characteristics of ultra high molecular weight polyethylene (UHMWPE ) modified with 2. 5wt%, 5wt% , 10wt% and 15wt% Cu( II ) chelate of bissalicylaldehyde-1,6-hexanediamine (Schiff base copper complex) against steel (45#) were tested by a pin-disk tribo-tester in dry. To investigate wear mechanism of the modified UHMWPE, topographies of worn surfaces were observed by SEM and their chemical composition was also analyzed by energy dispersive spectroscopy (EDS). The results showed that the friction and wear of UHMWPE were improved obviously by Cu(II) chelate of bissalicylaldehyde-1, 6-hexanediamine, and friction and wear of the rubbing pairs were reduced with the increasing content of Cu( II ) chelate of bissalicylaldehyde-1, 6-hexane diamine in UHMWPE, the friction and wear of UHMWPE modified with 10 wt% 1,6-diamine Schiff base Cu( II ) complex was minimum; the wear mode was abrasive wear, and selective transferring effect of Cu from Schiff base copper complex additive occured.关键词
