Plasma Electrolytic Oxidation (PEO) merupakan pelapisan permukaan logam dengan plasma anodisasi untuk menghasilkan lapisan tahan karat dan keras. Sifat lapisan yang dihasilkan dikendalikan oleh parameter proses seperti arus dan waktu pembentukan. Proses PEO dilakukan dengan 2 variasi yaitu variasi waktu dan variasi arus dalam larutan 0,5 M Na3PO4. Pada variasi waktu, arus yang digunakan adalah 0,5 A dengan waktu 1, 3, dan 5 menit. Sedangkan pada variasi arus digunakan arus 0,2; 0,3; 0,4 A dan ...

Phosphate Sludge (PS) waste has been a problem in metal surface finishing industry. The waste cannot be dumped in landfill due to the metal content. Valorisation of the waste will be beneficial in a way that it conserves natural reserves and reduces energy consumption. This paper describes the attempt of utilization of PS by mixing it in kaolin in preparation of ceramic bricks. A series of experiments showed that mixtures containing between 25–50 mass % ...

This research was done to investigate influence of the base metal surface roughness on the BAg-8 spreading behavior and to get a proper surface roughness number for large area brazing. The filler metal was melted at 830o C for 15 minutes on a S50C surface for with various roughness levels. After solidified, the spreading area was observed and characterized in macro and micro scale. The results show that physically the filler spreading consists of two ...
