Pengaruh Variasi Temperatur Quenching pada Aluminium Paduan AlMgSi-Fe12% terhadap Keausan

The purpose of this research  is to determine the effect of heat treatment hardening of Al Mg Si - 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  o C, 575  o C, 600  o C, and 625  o C, 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 mm 2 /kg. Test results on the  specimens  that have  received heat treatment hardening temperature 550  o C increased the wear value decreased to 1.7471E-07 mm 2 /kg. In materials with temperature heat treatment, 575  o C causes wear values were increased when compared with raw material,  respectively, 2,83739E-07 mm 2 /kg. In materials with temperature heat treatment 600  o C also causes wear values were increased when compared with raw material, respectively, 2,65105E-07 mm 2 /kg. Test results on the test material that ha s  received heat treatment temperature 625  o C increased the wear value decreased to 2.16777E-07 mm 2 /kg.
