Anodisasi merupakan suatu proses elektrokimia pada logam Aluminium dengan tujuan untuk memperoleh lapisan tipis Aluminium Oksida (Al2O3) yang sifatnya lebih baik dari pada logam Aluminium itu sendiri. Penelitian ini menitik beratkan pada proses anodisasi Aluminium yang menggunakan variasi larutan elektrolit campuran Asam Sulfat (H2SO4) dengan Asam Oksalat (H2O2C4). Dengan lamanya waktu 40 menit dengan rapat arus 3 Amp/dm² dan variasi suhu 5 ˚C, 10 ˚C, dan 15 ˚C. Terhadap karakteristik lapisan yang terbentuk setelah hasil anodisasi pengujian dilakukan dengan uji kekerasan permukan yaitu Microhardness Test dengan metode Microvickers. Dan hasil penelitian di dapat kekerasan permukaan tertinggi pada campuran Asam Sulfat 12 % dan Asam Oksalat 1 % pada suhu 5 ˚C sebesar 334.37 HVN, untuk Asam Sulfat 12 % dan Asam Oksalat 2 % pada suhu 5 ˚C sebesar 316.03 HVN, dan untuk Asam Sulfat 1 % dan Asam Oksalat 12 % pada suhu 5 ˚C tidak terjadi proses anodisasi.Kata kunci : Aluminium, Anodisasi, Larutan Elektrolit, Suhu, Microvickers.

Alloy 6061

Aluminium alloy 6061-T6 is utilized in aerospace industry for developing pressure vessel liner. Cold metal transfer is a promising welding process used in fabricating aluminium structures. The present work is focussed to achieve an optimum welding parameter for joining a 3.5-mm thick pressure vessel and to examine the mechanical properties and metallurgical nature of the weldment. The welded joint was evaluated as defect free using radiography test. The joint efficiency (66.61%) and measured microhardness of weldment (59.78 HV) exhibited promising results. The effect of grain coarsening in the heat affected zone (HAZ) and weld zone is attributed to the thermal gradients during welding. Dissipation of small amounts of strengthening elements Si and Mg during welding leads to reduction in mechanical properties. X-ray diffraction peaks revealed the presence of intermetallic Al–Si and Fe–Si in the weld zone. Fractography examination confirms the ductile type of failure in the fractured surface of the tensile samples.

Orthogonal experiments of micro mill-grinding were conducted on aluminium alloy 6061. Electroplated CBN compound tools were used in machining. Surface topography and roughness of the machined workpieces were measured and analyzed. Influence rules of radial cutting depth,feed rate and spindle speed on surface roughness in micro mill-grinding were studied. The results were compared with those in micro milling. It shows that the influence rules of processing parameters on surface roughness in micro mill-grinding are approximately same with those in micro milling. And in the same processing conditions, the surface roughness of micro mill-grinding is better than that of micro milling. The minimum value of surface roughness Ra of micro mill-grinding is 0.609μm in the experiments.
