Abstract
Proses pencampuran serbuk dalam fabrikasi komposit logam matriks copper merupakan salah satu proses yang penting untuk mencapai homogenitas campuran. Homogenitas tersebut sangat mempengaruhi pada sifat fisik dan sifat mekanik pada komposit logam matriks copper. Pada metode metalurgi serbuk, penggunaan mesin pencampuran serbuk jenis double cone dan v-cone mampu mengurangi segregasi terhadap hasil pencampuran dan memberikan homogenitas yang tinggi untuk fabrikasi komposit logam matriks copper. Pada review kali ini, dilakukan analisis mengenai pengaruh dari penggunaan mesin pencampuran serbuk jenis double cone dan v-cone terhadap homogenitas campuran yang dapat mempengaruhi sifat fisik dan sifat mekanik dalam fabrikasi komposit logam matriks copper. Untuk menunjang analisis tersebut dilakukan pengumpulan data dari sebelas jurnal dan dilakukan analisa homogenitas ditinjau dari uji SEM dan mikoskop optik dengan identifikasi ukuran serbuk dan parameter proses pencampuran. Selanjutnya dilakukan analisa sifat fisik yang ditinjau dari nilai densitas dan porositas. Dari hasil uji SEM dan mikroskop optic menunjukkan adanya homogenitas campuran dan degradasi ukuran serbuk menjadi irregular pada kedua mesin pencampuran. Penggunaan double cone mixer lebih efektif dalam menghomogenkan campuran dengan penggunaan ukuran serbuk 20,6-125 µm, rentang perbedaan antar ukuran serbuk ≤ 1: 2, proporsi serbuk reinforce 10-40%, variasi 2 serbuk, proses pencampuran serbuk selama 15-45 menit. Dari homogenitas tersebut, terdapat peningkatan nilai densitas sebesar 5,66%-13% dan penurunan nilai porositas sebesar 35-57% .

The process of mixing powder in fabrication of copper metals matrix composite is one of the important processes for achieving mixed homogeneity. This homogeneity greatly influences the physical and mechanical properties of copper metal matrix composites. In the powder metallurgy method, the use of double cone and v-cone powder mixing machines can reduce segregation of the mixing results and provide high homogeneity for fabrication of copper metal matrix composite. In this review, an analysis of the using mixing powder machine type of double cone and v-cone on homogeneity of mixtures that can affect on physical and mechanical properties in the fabrication of copper metal matrix composites. To support this analysis, eleven journals was collected and doing analysis of homogeneity in terms of SEM tests and optical microscopes by identyfication of powder sizes and mixing process parameters. Furthermore, physical characteristics were analyzed in terms of density and porosity. From the SEM test and optical microscopy showed the homogeneity of the mixture and the degradation of powder size became irregular in both mixing machines. The use of double cone mixer is more effective in homogenizing the mixture with the using of a powder size of 20.6-125 μm, the range of differences between powder sizes ≤ 1: 2, the proportion of powder reinforce 10-40%, variation of 2 powders mixture, and, powder mixing process for 15-45 minutes . From this homogeneity, there are increasing of density value of 5.66% -13% and a decrease in porosity value of 35-57%.
