Aluminium Alloy AA6060 Surface Treatment with High Temperature Steam Containing Chemical Additives
Materials Today: Proceedings, 2015Abstract The steam treatment process was employed to produce a conversion coating on aluminium alloy AA6060. The changes in microstructure and its effect on corrosion resistance properties were investigated. Various concentrations of KMnO4 containing Ce(NO3)3 was injected into the steam and its effect on the formation of steam-based conversion ...

Electrochemical behaviour of ZrO2 sol–gel pre-treatments on AA6060 aluminium alloy
Electrochimica Acta, 2007Abstract ZrO 2 pre-treatments applied with the sol–gel technique are a possible replacement of chromium based pre-treatments on aluminium alloys. The thickness and homogeneity of the films deposited on AA6060 alloy are strongly related to the process parameters like preparation of the surface, number of dips and thermal treatment of the film. ZrO 2

Journal of Adhesion Science and Technology, 2002
The wedge test was used to determine the durability of adhesively bonded joints of pretreated aluminium alloy AA6060 in a hydrothermal environment. Testing of joints bonded with the one-component epoxy adhesive XD4600 showed that the durability was higher for surfaces that were grit-blasted with alumina than for alkaline etched, FPL-etched, and ...

Effects of quench rate and natural ageing on the age hardening behaviour of aluminium alloy AA6060
Materials Characterization, 2016Abstract Quench sensitivity in Al–Mg–Si alloys has been largely attributed to the solute loss at the heterogeneous nucleation sites, primarily dispersoids, during slow cooling after extrusion. As such, the number density of dispersoids, the solute type and concentration are considered to be the key variables for the quench sensitivity. In this study,

Influence of Temperature and Strain Rate on the Mechanical Behaviour of Aluminium Alloy AA6060
Materials Science Forum, 2014In an attempt to improve the constitutive models for 6xxx aluminium alloys at high temperatures and high strain rates, a comprehensive test series has been carried out for AA6060. Uniaxial tension tests were performed at various strain rates from 0.01 s-1 to 1000 s-1 and temperatures from 20 °C to 350 °C.

Frictional conditions between alloy AA6060 aluminium and tool steel
AIP Conference Proceedings, 2011The frictional conditions in the new process of screw extrusion of aluminium have been investigated. The contact behaviour between the aluminum alloy and the tool steel in the extruder is vital for understanding the extrusion process. Using a compressive‐rotational method for frictional measurements the conditions for unlubricated sticking friction ...

Tensile tests on smooth and notched axisymmetric specimens were carried out to determine the large strain work-hardening curves and the ductile fracture characteristics of an AA6060 aluminium alloy for three different processing routes. The alloy was processed in three subsequent steps: 1) casting and homogenization, 2) extrusion, and 3) cold rolling ...

Conditions for Sticking Friction between Aluminium Alloy AA6060 and Tool Steel in Hot Forming
Key Engineering Materials, 2011The frictional conditions between an aluminium AA6060 alloy and tool steel in hot bulk forming have been investigated. The compressive-rotational method for frictional measurements, presented herein, represents an innovative approach for defining the thermo-mechanical conditions required for sticking friction at the interface between the two metals ...

Abstract The aim of the present paper is to study the hot deformation behavior of two different Al alloys (AA6060 and AA6063) by means of hot torsion tests in the 400-550°C temperature range, typical of real extrusion temperatures. The behavior of the alloys, in terms of equivalent stress vs.
