Kinetic Energy Penetrator
abstract: Kinetic energy penetrator (KEP) merupakan jenis proyektil yang menembus target melalui energi kinetik yang dihasilkan oleh kombinasi massa tinggi dan kecepatan sangat besar. Material depleted uranium (DU) telah lama digunakan sebagai penetrator karena densitasnya yang sangat tinggi serta fenomena selfsharpening, namun penggunaannya menimbulkan permasalahan serius terkait toksisitas, risiko kesehatan, dan pencemaran lingkungan. Oleh karena itu, tungsten karbida (WC) menjadi alternatif yang menjanjikan karena memiliki densitas tinggi, kekerasan sangat besar, dan stabilitas termal yang baik, meskipun sifat getasnya memerlukan pengembangan lebih lanjut melalui sistem pengikat logam. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan tembaga (Cu) dan variasi waktu sintering terhadap struktur mikro dan sifat mekanik paduan WC–Ni–Fe. Paduan diproses menggunakan metode metalurgi serbuk dengan komposisi WC dijaga konstan sebesar 91% wt dan rasio Ni:Fe sebesar 2:1, sedangkan kadar Cu divariasikan sebesar 0, 1, 3, dan 5% wt. Proses sintering dilakukan pada temperatur 1350 °C yang dialiri gas argon dengan waktu tahan 1,5 jam dan 3 jam. Karakterisasi material meliputi pengamatan struktur mikro dan distribusi unsur menggunakan FE-SEM, identifikasi fasa menggunakan XRD, pengujian densitas, kekerasan Rockwell, kekuatan tekan, serta evaluasi ketahanan korosi melalui metode potentiodynamic polarization dalam larutan NaCl 3,5%. Berdasarkan keseluruhan hasil pengujian, paduan WC–Ni–Fe dengan penambahan Cu sebesar 3% wt dan waktu sintering 3 jam menghasilkan kombinasi sifat mikrostruktur, mekanik, dan ketahanan korosi paling optimal dan memiliki potensi yang baik untuk diaplikasikan sebagai material KEP.
