Abstract

The purpose of this research is to determine the effect of heat treatment hardening of AlMgSi-Fe12% casting aluminium alloys on wear. The tests were carried out on specimens of raw materials and heat-treated specimens with variations of temperature used were 550 ^oC, 575 ^oC, 600 ^oC, and 625 ^oC, and used 15 minutes of holding time in each heat treatment, then quenching in SAE 20 oil. The method used for wear-tested was high speed ogoshi universal testing machine wear. The result had shown on raw material a specific wear rate was 2.256102E-07 mm²/kg. Test results on the specimens that have received heat treatment hardening temperature 550 ^oC increased the wear value decreased to 1.7471E-07 mm²/kg. In materials with temperature heat treatment, 575 ^oC causes wear values were increased when compared with raw material, respectively, 2,83739E-07 mm²/kg. In materials with temperature heat treatment 600 ^oC also causes wear values were increased when compared with raw material, respectively, 2,65105E-07 mm²/kg. Test results on the test material that has received heat treatment temperature 625 ^oC increased the wear value decreased to 2.16777E-07 mm²/kg.
