Investigation of multilayer coating of EN AW 6060 – T66 using friction surfacing
No full textThe objective of this research is to investigate observable process changes during multi-layer friction surfacing of EN AW 6060 aluminum, whether for repair, remanufacturing, or new part manufacturing. In this study, friction surfacing was performed with a 10-mm-diameter rod of EN AW 6060 aluminum at spindle speeds ranging from 1000 to 7000 rpm to create up to three layers of 40-mm-long deposits on a substrate of the same alloy. The process forces and layer temperatures were observed. Post-process measurement of flash geometry, layer geometry and microhardness were conducted with the motivation to understand the impact of multi-layer depositions on performance and identifying acceptable conditions required to achieve acceptable build quality. The thickness, deposition and joining efficiency of layers in the multilayer configuration remained consistent. Friction surfacing of EN AW 6060 aluminum allowed for high deposition rates of 9 kg/hr, when compared to other metal additive technologies

This article appeared in AIP Conference Proceedings 1896, 140012 (2017) and may be found at https://doi.org/10.1063/1.5008168.The microstructure evolution of the friction boundary layer of the aluminum alloy EN AW-6060 was investigated. Sticking friction tests at different temperatures and sliding speeds were carried out. A severe deformation below the friction surface was observed by means of LOM and EBSD mapping. Thus, the thickness variation and the grain structure of the high deformation zone could be described. Fibrous structure was observed at 300 °C and 400 °C, while equiaxed grains with high misorientation angle (>15°) were generated at higher temperatures. Additionally, abnormal grain growth and coarse grains were detected at high sliding speeds (10 mm/s, 42 mm/s) at 450°C and 500 °C respectively

Electrochemical Properties of Aluminium Alloy EN AW 6060
Full text linkAluminjske slitine serije 6xxx karakteriziraju odlična deformabilnost, mogućnost toplinskog očvršćivanja, dobra otpornost koroziji i relativno dobra mehanička svojstva. Stoga se u obliku poluproizvoda (u vidu šipki i cijevi) dosta često upotrebljava kao konstrukcijski materijal gdje se traži relativno mala masa, srednja mehanička svojstva i dobra otpornost vanjskim utjecajima. U ovom radu elektrokemijskim mjernim tehnikama određena je korozijska otpornost slitine EN AW-6060 (u ekstrudiranom stanju) u kloridnom mediju (0.5M NaCl). Rezultati ispitivanja pokazali su da je slitina EN AW-6060 sklona jamičastoj (pitting) koroziji, što je u vezi s karakerističnom mikrostrukturom slitine.The 6xxx series aluminium alloys are charactarised by excellent extrudability, heat treatment hardening, good corrosion resistance, and relativly good mechanical properties. Therefore it is frequently used as an extruded product (bars, tubes) for structures requiring low weight, average mechanical strength, and good corrosion resistance. In this article, electrochemical measurements were used to determine corrosion resistance of En AW-6060 (extruded) in 0.5M NaCl chloride media. The results have shown that EN AW-6060 is sucseptible to pitting corrosion, which is due to microstructural characteristics of that alloy
