Paper Abstract

Impact-sliding wear of aluminum bronze against titanium alloy and 2Cr13 steel have been conducted using impactsliding wear test rig which was developed independently. Some non-destructive examinations have been performed on worn specimens, using weighing, 2D and 3D profilometry, scanning electron microscopy and EDS technology. Using laser scanning confocal microscope (LSCM), it has been found that the surface of aluminum bronze which wears against titanium alloy is much coarser than the surface which wears against 2Cr13 steel. Results of wear volume show clearly that although the hardness of titanium alloy has greater value than aluminum bronze, the wear volume of titanium alloy has much greater value compared with aluminum bronze. It has been found that there is remarkable material transferring from titanium alloy to aluminum bronze and little material transfer from aluminum bronze to titanium alloy. For the impact-sliding wear between aluminum bronze against 2Cr13 steel, the hardness of aluminum bronze has greater value than 2Cr13 steel, the wear volume of aluminum bronze has much greater value compared with 2Cr13 steel, whose wear volume can be ignored. Using EDS technology, it has been found that there is material transferring from aluminum bronze to 2Cr13 steel and material transferring from 2Cr13 steel to aluminum bronze can be ignored. Through the SEM pictures of worn surfaces and worn debris, flaking, particles and micro-cracks can be found on the worn surfaces. The wear mechanism of aluminum bronze against titanium alloy and 2Cr13 steel is delamination wear.
