Abstract

Pengecoran squeeze atau yang sering juga disebut penempaan logam cair adalah proses dimana logam cair dibiarkan membeku dalam cetakan yang diberi tekanan ekternal. Penelitian ini bertujuan untuk mengetahuipengaruh tekanan terhadap struktur mikrodan kekerasan pada proses pembuatan kampas rem dengan penambahan titanium (Ti) paduan aluminium daur ulang. Paduan dilebur pada dapur peleburan dan dituang pada temperatur 700 kedalam cetakan yang telah dipanaskan pada temperatur 300 selanjutnya diberi tekanan dengan variasi tanpa tekanan, tekanan 104MPa, 149Mpa dan 194MPa selama 8 menit. Hasil penelitian menunjukkan bahwa semakin tinggi tekanan yang diberikan porositasnya semakin sedikit, SDAS semakin kecil, dan nilai kekerasan naik.

Katakunci: Pengecoran squeeze, daur ulang,  tekanan.
