Abstract

Telah dilakukan penelitian untuk mengetahui pengaruh pemanasan serbuk Al pra-kompaksi terhadap sifat fisis komposit Al/SiC hasil metode metalurgi serbuk. Penelitian dilakukan dengan bahan dasar serbuk aluminium, serbuk silikon karbida dan serbuk zinc stearat. Pembuatan komposit Al/SiC dilakukan dengan menggunakan variasi temperatur pemanasan matrik yaitu 40°C, 60°C dan 80°C, serta temperatur sinter yaitu 400°C, 500°C, dan 600°C. Identifikasi sifat fisis yang dilakukan yaitu densitas, porositas dan kuat tekan sedangkan analisa fasa dan mikrostruktur menggunakan pengujian Difraktometer Sinar-X (XRD) dan Scanning Electron Microscopy (SEM). Analisis data XRD dilakukan dengan menggunakan software Match!. Berdasarkan hasil penelitian menunjukkan bahwa pemanasan matrik Al prakompaksi memberikan pengaruh terhadap densitas dan porositas. Semakin tinggi temperatur pemanasan matrik Al, densitas komposit Al/SiC semakin tinggi dan porositas semakin kecil. Semakin tinggi densitas sampel maka kemampuan komposit Al/SiC dalam menahan beban atau gaya mekanis dari luar semakin besar. Dari analisis XRD menunjukkan bahwa terdapat fasa baru yang muncul selama proses pembuatan yaitu Al2O3-γ dan terlihat bahwa partikel penguat SiC terdistribusi kurang merata terhadap matrik Al dilihat dari analisa mikrostruktur menggunakan SEM. ==================================================================================================== Have been carried out research to determine the effect of heat treatment for Al powder pre-compaction to physical properties Al/SiC composites by powder metallurgy method. The research have been done using the heating temperature matrix that is 40oC, 6 oC and 8 oC and sinter temperature of 400 oC , 500 oC and 600 oC variation. The identification of physical properties that do is density, porosity and compressive strength while the phase and microstructure analysis using X-Ray diffractometer (XRD) and scanning microscope electron (SEM). The XRD data analysis performed by using the software Match!. Based on the result of this research, the heat treatment for Al pre-compaction giving effect to density and porousity. For the temperature increase for Al matrix, the density of Al/SiC increase too an the porousity is getting small. With increasing density, ability of Al/SiC composites in mechanical load or withstand the force from outside is greater. From XRD analysis showed that there is a new phase that emerged during the manufacturing process, namely Al2O3-gamma and seen that particles less evenly distributed SiC with matrices Al viewed from the analysis of SEM microstructure.
