wire-brushing is used for different purposes such as removing metal surfaces oxides, increasing surface brightness, improving fatigue properties and surface activation before coating. the wire-brushing severely scratches and stirs the metals in the surface layers, so that complicated metal flow gives rise to very large amount of plastic strain and increases dislocation density of the surface la...

Poros merupakan komponen yang sangat penting dalam generator karena poros penerus daya. sendiri sering mengalami kegagalan kerja seperti patah akibat dari beban berlebih, untuk itu penelitian ini bertujuan mendapatkan material aman digunakan pada 500 watt dengan cara simulasi pembebanan menggunakan Software CAD. Material akan di uji yaitu AISI 1020 dan Aluminium Alloy 6061. Penelitian metode ek...

In this work, the effect of ageing and retrogression on polarization resistance Al 6061 was assessed, in order to improve corrosion alloy with a negligible tensile strength. The behavior studied by exposing an simulated marine environment, then, current density (icorr) measured. obtained results were correlated strength (TS) reported elsewhere both measured, icorr TS modeled multiple linear reg...

Regulation of residual stress in a component is the key to improving its service performance. A cold expansion method was proposed for reducing 7050 aluminium alloy curved frame forging after quenching. The effect on and equivalent plastic strain distribution investigated. results showed that maximum at center thickness reduced from 153 MPa 94 expansion, while it decreased 283 120 surface with ...
