The horizontal volume is chiselled and shaped with a glacial precision that belies the building's quotidian function and context, The concrete is flawless and the joints between the anodised aluminium panels wafer thin.
For such technical applications, hard anodised coatings must have a consistent hardness of 400-600 HV across the entire section.
Figure 2a/b shows the Vickers Hardness HV (calculated from the indentation hardness HIT) and the indentation modulus EIT of two coatings--a hard anodised coating (480 HV) of 11 [micro]m thickness (shown in red) and a soft anodised coating of 14 [micro]m thickness (shown in blue).
The properties of DiamonDyze ceramic anodised aluminium are summarised in the table opposite.
Over the years there have been many ways of impregnating the porous alumina structure of anodised aluminium with electrodeposited metal (as in electro colouring), with dyestuffs and with finely divided polymers, notably PTFE, but none that have given such a wide range of improvements to anodising as the ceramics used in the DiamonDyze process.
The need to control the quality of anodised products is difficult when production quantities are modest.
The items to be anodised and dyed are machined aluminium components in varying sizes and this was a complete package, covering plant design to suit the available workshop space, manufacture and shipping of the plant with additional training on site as the client was new to the process.
The Oxidite A products will also improve the consistency and uniformity of the anodised coating and will increase the coating rate.
Where the use of boiling water is preferred, the high temperature additive will reduce the formation of Bohmite smut on the anodised surface.
