Taguchi Method Approach to Optimize Manufacturing Process Parameters of Aluminum-5 % Fly Ash Alloy Using Powder Metallurgy
Fly ash is waste of coal combustion which can be used in Aluminum alloy. In this research Aluminum is mixed with fly ash that used powder metallurgy method. Aluminum powder is produced by Merck German which is in irregular form and has homogeneous particles, while fly ash is got from residual combustion coal in forging section of Politeknik Negeri Sriwijaya (Polsri) mechanical workshop which is processed until grains size 140 and 270 mesh. Aluminum Powder had mixed with weight fraction 5 % of fly ash for an hour then is pressed with holding time 60 and 120 seconds, compacting pressure are 139 N/mm2 and 275 N/mm2 using cold iso-static pressing. After that green body is resulted then is being sintered until 5500C. Taguchi Method orthogonal L4 is used to find out factors which influence optimum condition of Brinell’s hardness Aluminum/5% fly ash. The result of analysis using ANOVA is grains size factor, holding time, and compacting pressure has affected significantly to hardness of Aluminum/5% fly ash.
