| Abstract | ||
| To The aim of this research is to study the effect of 5 wt % Al2O3 addition Al- base alloy on sliding wear resistance under dry sliding conditions using pin- on- disc machine . Wear test was conducted after squeeze casting under different pressure ( 30 , 60 , 90) Mpa. The results show that wear rate for Al- base alloy composites increases with increasing applied load but decreases with increasing sliding speed conditions . The composites which casting at 90 Mpa pressure represents lower wear rate than those which cast at 30, 60 Mpa pressure and the base alloy . The results also observed that the coefficient of friction increasing with increasing sliding time but reaches to the steady state after 200 sec. The microhardness and ultimate tensile strength increases with increasing squeeze casting pressure. | ||
