Titanium–aluminum–nitride coatings for satellite temperature control

Characterization and temperature controlling property of TiAlN coatings deposited by reactive magnetron co-sputtering

“…Furthermore, TiAlN coatings exhibit good performance on hydrogen permeation barrier [9]. Besides the applications of TiAlN coatings mentioned above, another prospective application is on the temperature controlling for the satellite [10,11]. The satellite in outer space is not only subjected to ultra-vacuum, strong ultraviolet radiation, the bombardment of charged particles but also the dramatic change of the temperature.…”

BepiColombo - A Mission to Mercury

“…They are also electrically conducting, and therefore suitable as coatings for probes used in electrical fields. The optical properties of thin films of TiN and TiAlN has previously been reported (Karmhag and Ribbing, 1999;Brogren et al, 2000). Calculations in an Earth-bound orbit resulted in temperatures of 110 and 34 °C respectively.…”

“…Temperature calculations of thin film TiN coatings has previously been reported (Karmhag and Ribbing, 1999), as well as thin film TiAlN (Brogren et al, 2000). TiN coatings manufactured by high temperature nitridation have also been investigated (Veszelei, 1997).…”

“…Calculations in an Earth-bound orbit resulted in temperatures of 110 and 34 °C respectively. The stoichiometry of the TiAlN film was Ti 0.16 Al 0.43 N 0.41 (Brogren et al, 2000), and it was deposited onto Al. Samples of TiAlN were manufactured from a Ti 0.5 Al 0.5 target by sputtering with nitrogen, and also by post-nitridation of sputtered TiAl films.…”

Colour control and selectivity in TiAlN solar-thermal absorbers

“…a lower equilibrium temperature, to a satellite exposed to solar radiation, but free to radiate towards space. 10 At a later stage it was realized that the possibility to control the colour of TiAlN-coatings in a two target sputtering process opened up for the deposition of coloured, selective solar absorbers as mentioned above. 3 The interband transitions in the mother compound TiN were modified so as to give a modest reflectance drop in the visible range.…”
