Abstract

Perlakuan permukaan shot peening paling banyak diaplikasikan untuk meningkatkan ketahanan fatik dan korosi pada konstruksi pesawat terbang. Penelitian ini bertujuan untuk mempelajari pengaruh shot peening mesin otomatis terhadap laju perambatan retak fatik pada material Al 7050-T7651 serta membandingkannya dengan shot peening mesin manual.Spesimen dibentuk sesuai dengan standar ASTM E647, diidentifikasi dengan nama base metal shot peened– automatic machine (BMSPA). Proses perlakuan shot peening dilakukan di area surface treatment PT. Dirgantara Indonesia menggunakan mesin otomatis. Selanjutnya pengujian perambatan retak fatik dilakukan dengan mesin Servopulser di Lab. Bahan Teknik Jurusan Teknik Mesin UGM, dengan beban sekitar 11% dari tegangan tarik maksimum (spesimen standar ASTM E8M) yang dihubungkan dengan analisis beban kombinasi, dengan stress ratio R=0,1. Data hasil uji tersebut diolah menggunakan metode incremental polynomial untuk mendapatkan hubungan da/dN - ΔK. Hasil uji perambatan retak fatik menghasilkan angka konstanta Paris A=1,874×10-8dan n=1,06 jika dibandingkan hasil penelitian sebelumnya untuk spesimen AR as received material-tanpa perlakuan dengan A=1,288×10-9dan n=2,02; dan BMSP base metal shot peened-manual machine  dengan A=1,286×10-9 dan n=2,01. Semakin rendah nilai konstanta Paris, menunjukkan semakin rendahnya laju perambatan retak fatik. Sehingga perlakuan shot peening dengan mesin otomatis lebih mampu menurunkan laju perambatan retak fatik daripada mesin manual atau tanpa perlakuan.
