Electrical connection of dissimilar metals will lead to galvanic corrosion. Therefore, overall surface treatment is necessary for the protection of dissimilar metal welded parts. However, serious unbalanced reactions may occur during overall surface treatment, which makes it difficult to prepare integral coating. In this paper, an overall ceramic coating was fabricated by plasma electrolytic ox...

The viscoelastic response of commercial aluminum alloys 7075-T6 and 2024-T3 as a function of temperature is presented. Experimental data are obtained with a dynamic-mechanical analyzer (DMA) at different loading frequencies and compared with the available transmission electron microscopy (TEM) and differential scanning calorimetry (DSC) data. The effect of successive microstructural transformat...

Sprocket merupakan salah satu bagian dari sistem transmisi yang biasa digunakan pada kendaraan bermotor. Pada eco-car tim Antawirya Universitas Diponegoro juga menggunakan sprocket sebagai komponennya. Saat memulai balapan pertama dan melakukan full throttle, menjadi gagal karena deformasi terjadi sprocket. mengalami plastis kemudian menyebabkan rantai keluar jalurnya terlepas. Tujuan kajian in...
