Effect of Pb and Sn Adding on Dry Sliding Wear Behavior of á-Brass (70/30)

Engineering and Technology Journal, 2009, Volume 27, Issue 7, Pages 258-268

This work is concerned with a study of dry sliding wear of α–Brass (70/30) with
addition of lead and tin(3%wt) for each one alloy. Three brass alloys were prepared by
melting and pouring in steel molds. A Pin -on-Disc technique was used. The effect of
applied loads and sliding times on wear rate were examined. The results show that the
wear rate increases with increasing applied loads and with increasing sliding time at
constant sliding speed (2.7m/s) while hardness of steel disc was 35 HRc .
The results also show that the brass alloy containing 3% tin has more
wear resistance than that of other brass alloys.
