Karakteristik Pengaruh Suhu Sintering terhadap Kekerasan, Porositas dan Penyusutan Roda Gigi Lurus berbahan Serbuk Besi

Spur gears are the most common type of gears used as engine components. The powder used in this study was 100 mesh iron (Fe) powder then compacted with a force of 8 tons and sintered at several temperature variations are 800, 900, 1000, 1100, and 1200 oC taken from 0.5-0.8 melting points (Tm) main powder. This study aims to look at the characteristics of the effect of sintering temperature on hardness, porosity, and shrinkage of spur gears made from iron powder (Fe). The sintering time is made constant at 60 minutes. Several tests were conducted to achieve the objectives of this study such as the calculation of the percentage of shrinkage and porosity, porosity testing on microstructure with metallographic observations, and micro hardness testing of Vickers. The results show that as the sintering temperature increases, shrinkage increases, porosity decreases, and the hardness value increases. There are some results of research that are not suitable for the porosity and hardness value of the product. This is due to several factors including difficult to achieve uniformity of density, imperfect material preparation, and different compacting value settings in each sample due to the mechanical press machine used.
