Abstrak Penelitian ini bertujuan untuk mengetahui variasi temperatur sintering, dengan tekanan kompaksi 3200 psi dan lama waktu penahanan sintering 20 menit pada aluminium paduan silikon berbahan dasar serbuk kaca yang dicetak menggunakan cetakan (molding) dengan proses metalurgi serbuk terhadap struktur mikro, kekerasan dan densitas. Material yang digunakan dalam penelitian ini berasal dari serbuk aluminium 70% dan serbuk kaca 30% menggunakan variasi ukuran butiran serbuk 150, 200, 250 mesh. Serbuk aluminium dan serbuk kaca dicampur selama 10 menit, kemudian dimasukkan ke dalam cetakan dan dilakukan kompaksi pada suhu ruang dengan tekanan 3200-psi sehingga menjadi green body. Green body ini dilakukan proses pemanasan (sintering) pada variasi suhu 400, 500, dan 600-⁰C selama 20 menit. Hasil penelitian menunjukkan bahwa pada suhu 600 ⁰C menghasilkan struktur mikro yang memperlihatkan porositas di dalam lapisan lebih kecil daripada di permukaan karena pembentukan fase Al-Si. Dengan hasil kekerasan paling tinggi sebesar 33.33 HV dan densitas sebesar 2.28 g/cm3.Kata kunci: Metalurgi Serbuk, AlSi, Struktur mikro, Kekerasan, DensitasAbstract This study aims to determine the variation in sintering temperature, with acompaction pressure of 3200 psi and a 20-minute sintering holding time in silicone alloy aluminum made from glass powder molded using molding (molding) with a powder metallurgy process against microstructure, hardness and density. The material used in this study came from 70% aluminum powder and 30% glass powder using powder grain size variations of 150, 200, 250 mesh. Aluminum powder and glass powder are mixed for 10 minutes, then put into a mold and compacted at room temperature with a pressure of 3200-psi so that it becomes a green body. This green body is carried out a heating process (sintering) at temperature variations of 400, 500, and 600-⁰C for 20 minutes. The results showed that at a temperature of 600 ⁰C produced a microstructure that showed porosity within the layer smaller than on the surface due to the formation of the Al-Si phase. With the highest hardness yield of 33.33 HV and a density of 2.28 g/cm3.Keywords: Powder Metallurgy, AlSi, Microstructure, Hardness, Density

Titanium Nitride coating has attracted much interest in increasing the hardness of aluminum alloys. This study aims to investigate the effect of Ar: N gas mixture and time on increasing the hardness of aluminum alloys using DC sputtering. Preparation of TiN thin films on aluminum alloy substrates using flowing gas mixture parameters and time. First, the layer of TiN was deposited on the sample with a gas mixture of 90Ar:10N; 80Ar:20N; 70Ar:30N; and 60Ar:40N (%) for 60 minutes. Then the optimum gas mixture that produces the highest surface hardness is used in the second process with time variations of 30, 60, 90, and 120 minutes. The results showed that the highest hardness was achieved in a gas mixture of 70Ar:30N and 60 minutes. The TiN phase formed on the aluminum surface was identified by XRD, while the surface morphology was observed by SEM. Compared with untreated samples, the hardness of treated samples increased significantly.

“…In this study, the selected material to be coated is Tungsten Nitride, with the consideration that the WN coating has very superior properties, namely having hardness, wear resistance, abrasion resistance, and very high corrosion resistance and is inert [14][15][16]. The coating method applied in this research is the home-made D-C sputtering technique [17][18][19][20][21][22]. In this method, the sputter gas is argon (Ar), the reactive gas is nitrogen (N2), while the sputtering target is pure tungsten (W) with a diameter of 5 cm and a thickness of 3 mm.…”

316L stainless steel (SS) is an alloy steel that is not easily corroded, so it is widely used for biomaterial applications. In addition to being resistant to corrosion, 316L SS is also inexpensive when compared to other medical metals. However, 316L SS has relatively low hardness and wear resistance, thus this weakness must be improved. By heat treatment, it is impossible to improve the SS alloy, so other techniques must be applied. In this study, improvement of surface hardness of 316L SS by coating tungsten nitride (WN) using DC-sputtering method has been conducted. The sputtering process was implemented by varying the sputtering pressure of 1.8×10-2, 2.3×10-2 and 2.8×10-2 Torr. Furthermore, the composition ratio of Ar and N2 gases were varied i.e 70:30, 80:20 and 90:10 with a voltage of 4 kV and deposition time of 120 minutes. After the coating process, hardness testing was carried out using the Vickers hardness test with a load of 25 gf. The formation of tungsten nitride was also analyzed using XRD. The highest hardness in order of 938.64 VHN is achieved at a pressure of 2.8×10−2 Torr and the ratio of Ar:N2 gas was 90:10. From the XRD analysis, the layer formed is a W+WN layer which is shown at the peaks at a scattering angle of 2Ɵ is 43.55º; 2Ɵ is 39,530º; 2Ɵ is 56,880º; and 2Ɵ is 71,550º.
