ABSTRAK Aluminium merupakan logam yang paling banyak digunakan setelah baja, dengan karakteristik utamanya adalah ringan (berat jenis = 2.7 g/cm3), memiliki konduktivitas panas dan listrik tinggi, ketahanan korosi baik. Penggunaan aluminium menempati urutan kedua besi baja sebagai bahan untuk komponen industri otomotif, salah satu penggunaanya yaitu berupa pada mobil. seri 7075 mana sifat baik ...

In this study, MAO process, which is one of the surface coating methods, was applied to 7075-T6 Al alloy in a thin thickness and relationship between its mechanical properties compared uncoated state investigated. Surface microstructure images prepared samples, from cross section eds analysis were measured by scanning electron microscope (SEM). With XRD analysis, peaks material on made determin...

Grit blasting and laser processing are two common methods used for surface microtexturing to enhance coating adhesion strength. This paper reports a thermomechanical method of Al 7075 alloy using nanosecond pulsed generate large increase in area. The entire area the substrate was microtextured melting, ablation, resolidification. morphology consisted tightly packed pillar-like features. microte...

Aluminum alloy 7075 is an important engineering material for ship structures. However, the corrosion of Al alloys generally exists in various environments, especially marine environment. Currently, behaviors sulfate-reducing bacteria (SRB) environment has not been well-addressed. In this paper, effect SRB on aluminum was studied by adding to real seawater. The microstructure and grain orientati...

Studying the specific energy during material removal mechanism at micro-scale provides a better understanding of transition between different regimes. Modeling into components sliding, plowing and cutting helps to analyze influence grain properties process parameters, mechanical on phases removal. Present research put forth comprehensive model consumption for abrasive cut off operating based in...
