Determination of the effect of artificial aging parameters on dry sliding wear resistance of 6013 aluminum alloy (Al-Mg-Si-Cu)
Abstract
In this study, the effect of artificial aging parameters, applied to AA6013 aluminum alloyscommonly used in the automotive and aerospace sectors, on wear resistance was examined. Forthis purpose, AA6013 aluminum alloy samples were solutionized at 575 °C for 60 minutes andthen they were artificially aged for 2, 4, and 6 hours at 180 and 200 °C temperatures. Meanhardness was measured as 66.6 HV in the solutionized samples taken. It was determined that as aresult of artificial aging, α-AlFeMnSi intermetallic phase precipitation were formed between α-Algrains. By the effect of precipitation hardening, an increase in hardness was observed in allartificially aged samples; the highest hardness was found as an average of 149.3 HV in AA6013samples aged artificially for 2 hours at 200 °C. A general decrease in the friction coefficients ofsamples aged at both 180 °C and 200 °C was observed along with the artificial aging temperature.The lowest specific wear rate was determined as 3.542x10-3 mm3/Nm in the AA6013 sample agedartificially for 2 hours at 200 °C.
