Description

Top bracket merupakan salah satu komponen pada unit excavator yang merupakan bagian dari bom. Komponen ini berhubungan dengan komponen lainnya (arm) melalui pin untuk menggerakan bucket, akibat adanya gerakan hidrolik dari aktuator yang terpasang pada kedua komponen tersebut. Pada proses pemakaian sedang berlangsung terjadi kerusakan berupa patah pada bagian top braket yang berhubungan dengan arm. Untuk mengetahui penyebab kerusakan telah dilakukan serangkaian pengujian terhadap komponen tersebut berupa fraktografi dengan menggunakan mikroskop optik dan mikroskop elektron (SEM/EDX), uji keras mikro dan metalografi telah dilakukan. Dari serangkaian pengujian dan evaluasi dapat diketahui faktor penyebab kegagalan, yaitu material terbuat dari bahan baja karbon paduan rendah (Si-Mn) sesuai dengan standar JIS : SCSiMn1h. Hasil analisa terhadap bidang patahan (fraktografi), patahan dapat dikelompokkan kedalam patah lelah, awal patahan berawal dari permukaan bagian dalam (ID). Penyebab awal patahan adalah pada permukaan terdapat banyak inklusi, struktur mikro yang tidak homogen dan memiliki gradian kekerasan akibat proses perlakuan panas yang tidak sempurna.
