31、ol systems onboard spacecraft are often based on the thermo-optical properties of the surfaces, namely emissivity and absorbance. The ratio of these two properties defines the equilibrium temperature of the surface. This Standard provides requirements for black-anodizing surface treatment applied on

32、 metallic surfaces to achieve an emissivity versus absorbance ratio close to unity, as requested for many applications. DIN EN 16602-70-03:2015-01 EN 16602-70-03:2014 (E) 6 1 Scope This Standard defines requirements for measurements and verifications to guarantee that an anodized coating is adequate

33、 for the intended application. The requirements set by this Standard ensure high reliability of surface treatments intended to withstand normal terrestrial conditions and environment loads imposed on spacecraft and associated equipment where surfaces require high solar absorptance, high emittance, h

Comp

46、ounds or dyes are sealed in the oxidized layer, thus providing the required optical or thermo-optical properties to the surface. For space applications, only inorganic dyes are suitable, as radiation do not strongly impact on their thermo-optical properties. Depending on the specific project require

47、ments, the coating fulfils part or all the acceptance criteria given in this Standard. Not all metals and alloys are suitable for black- anodizing treatment. The most commonly treated are titanium, aluminium and their alloys. In particular, the composition of the alloy, the manufacturing process and

48、 the alloy temper can have an impact on the response to the black- anodizing. Aluminium alloys containing a high amount of copper (5 %), zinc (6 %) or silicon (5 %) are known to respond poorly to some treatments. Wrought alloys are generally easier to treat than cast alloys. The manufacturing proces

49、s of the part to be coated can have an impact on its response to the black- anodizing process. Also the geometry of the hardware can limit the possibility to coat the part. The surface quality of the parts to be coated has an influence of the coating results, since the anodization layer mimics the surface characteristics of the underlying substrate. Several requirements are therefore identified in order to select and prepare suitable work-pieces. Annex A describes for in
