The utilisation of suspensions as the spraying consumables is, for the first
time, making it possible to apply sufficiently thin, metallic, thermally sprayed
coatings made of nickel-chromium alloys (< 30 µm) in order to be able to use
them effectively as heating coatings even in the case of limited available surfaces.
The area heating capacities of 25 W/cm2 feasible with them and heating
rates of 15 K/s even surpass the performances of many ceramic heating
elements and, in a flexible way, the heating coatings can be applied directly
to the components to be heated.
