In this study the effect of artificial aging time on adhesive wear of AA(6061-T6) aluminum alloy was investigated for the specimens groups (A , B , C and D)which manufactured in the dimensions of ( 20*10)mm according to ASTM, heat treatment was implemented to specimens groups( B , C and D) which include solution zing at temperature of 5000 C for (1 hour) then quenching in water and artificial aging for (1,3,5 ,hr.) at 1800C The resulting phases after each heat treatment was tested by x –ray diffraction and microstructure was also examined to understand the nature of structure then hardness test was implemented
Adhesive wear test have been conducted on aluminum alloy AA 6061 T6 at variable (time ,loads, and sliding speed ) using pin on disc method. The results showed that increasing of aging time increases hardness then decreasing wear rate.
