تأثير إضافة الرصاص و القصدير على سلوك البلى الانزلاقي الجاف لسبيكة البراص الفا (3070)‎

Abstract EN

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.
