چکیده
|
The influence of 4.5 wt.% copper addition on wear behavior of as-cast al-12si alloy prepared by gravity casting is investigated in dry sliding against a steel counterface using a pin-on-disk apparatus. the microstructures of test alloys and worn surfaces were examined by scanning electron microscopy and energy dispersing x-ray spectroscopy. the addition of copper to the binary al-12si alloy led to the precipitation of cual2 phase. copper addition resulted in a refinement of α-al and a minor modification of eutectic si. the al-12si-4.5cu alloy showed a higher wear resistance as compared to al-12si binary eutectic alloy. © 2015 jordan journal of mechanical and industrial engineering. all rights reserved.
