Identifikasi Karakteristik Mekanis Bantalan Luncur Motor Starter Dari Serbuk Tembaga Alumunium

Abstract

There are many attempts to support the development of industry in Indonesia, especially on automotive sector, one of them is by replacing import components with local component products. Bushing is one of imported component that widely used on automotive application including motor strater. Bushing usually made of copper alloy such as brass, bronz or babbit in a solid form by casting or extrusion process. In this research powder metal technology is used to process Cu-Al powder to become slide bearing of motor starter. It is expected that powder metal process not only increasing local content in automotive parts but also providing better quality by increasing life time of bushing compared to ordinary one. i.e: 250 MPa, 350 MPa and 450 MPa, and then all specimens were sintered at different temperatures : 400 0 C, 500 0 C dan 600 0 C for 1 hour. After sintering specimens were air cooled to room temperature. After physical and mechanical test it can be deduced that bushing made by powder metallurgy method could increase its mechanical properties and as aresult improve its life time operation.

SIFAT MEKANIK DAN STRUKTUR MIKRO KOMPOSIT ALUMUNIUM TEMBAGA (Al-Cu) DENGAN VARIASI KOMPOSISI

“…Penelitian diawalai dengan pengamatan dilapangan dimana berupaya untuk mendapatkan metode farbikasi yang lebih efekti. Dari studi literatur dinyatakan bahwa metode metalurgi serbuk secara umum lebih efisien dibanding dengan metode lain karena metode ini tidak menghasilkan limbah [6][7]. Metode ini dengan cara mencetak komponen sesuai dengan bentuk dan ukuran yang desain yang dibutuhkan.…”
