my.unimap-338102014-04-18T07:48:22Z Effect of space holder and compaction pressure on the porosity of sintered copper Shamsul Baharin, Jamaludin, Prof. Dr. Chong, Xin Yi Alida, Abdullah Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr. sbaharin@unimap.edu.my alida6986@gmail.com vc@unimap.edu.my Copper Porous Powder metallurgy Sintering Space holder Link to publisher's homepage at http://www.ttp.net/ The effect of space-holder content on the porosity of sintered copper that was fabricated by powder metallurgy technique has been investigated. Carbamide was used as space-holder and the content selected was 10 wt. %, 20 wt. % and 30 wt. %. A roll mill was used to mix the copper powder and the carbamide particles with rotation speed of 160 rpm for 2 hours. The mixture was compacted by hand press at 200-350MPa and sintered under argon atmosphere at 800°C. True density of the sample was determined by a gas pycnometer. Bulk density was determined using mass and volume of the sample. Result shows that the sintered porous copper with 30 wt. % of space-holder produced the highest porosity and the lowest density. Microstructure of pores was analyzed by a scanning electron microscope (SEM) which reveals the elongated pores interconnected to each other. 2014-04-18T07:48:22Z 2014-04-18T07:48:22Z 2013 Article Advanced Materials Research, vol. 795, 2013, pages 82-86 978-303785811-0 1022-6680 http://www.scientific.net/AMR.795.82 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33810 en Trans Tech Publications |
