英文摘要	Reciprocating ball-on-flat dry sliding friction and wear experiments have been conducted on single-phase gamma-Y2SO7 ceramic flats in contact with AISI 52100 bearing steel and Si3N4 ceramic balls at 5-15 N normal loads in an ambient environment. The kinetic friction coefficients of gamma-Y2Si2O7 varied in the range over 0.53-0.63 against AISI 52100 steel and between 0.51-0.56 against Si3N4 ceramic. We found that wear occurred predominantly during the running-in period and it almost ceased at the steady friction stage. The wear rates Of gamma-Y2Si2O7 were in the order of 10(-4) mm(3)/(N m). Besides, wear debris strongly influenced the friction and wear processes. The strong chemical affinity between gamma-Y2Si2O7 and AISI 52100 balls led to a thick transfer layer formed on both contact surfaces of the flat and counterpart ball, which changed the direct sliding between the ball and the flat into a shearing within the transfer layer. For the gamma-Y2Si2O7/Si3N4 pair, a thin silica hydrate lubricant tribofilm presented above the compressed debris entrapped in the worn track and contact ball surface. This transfer layer and the tribofilm separated the sliding couple from direct contact and contributed to the low friction coefficient and wear rate. (C) 2009 Elsevier B.V. All rights reserved.
