Using atmospheric plasma spraying it is possible to form coatings from metallic alloys, ceramic, polymer and cermet powder materials.
Materials and Methods Atmospheric plasma spraying technology (APS MF-P-1000 (GTV) unit with a F4MB-XL plasma gun (Oerlikon Metco)) was used to deposit the coatings from powder materials on grit blasted metal substrate (construction steel coupons with diameter 25.4 mm and height 5 mm).
XRD phase analysis showed that mostly all of the powder sprayed materials was under the influence of the environment during spraying.

Wagner Chemnitz University of Technology, Institute of Materials Science and Engineering, Erfenschlager Str. 73, 09125 Chemnitz, Germany * S+C Extrusion Tooling Solutions GmbH, Kaiserau 2, 51789 Lindlar, Germany aphilipp.frint@mb.tu-chemnitz.de Keywords: equal-channel angular pressing (ECAP), scale-up, industrial scale, mechanical properties, ultrafine-grained (UFG), microstructure, aluminium alloy Abstract: Future applications of ultrafine-grained, high performance materials produced by equal-channel angular pressing (ECAP) will most likely require processing on an industrial scale.
Ultrafinegrained (UFG) materials typically exhibit average grain sizes in the range of 100 nm to 1 µm.
The majority of previous investigations have been done on materials processed by ECAP in laboratory scale.
This technique in principle enables the use of severely plastically deformed materials in structural applications and hence helps overcome one of the most persistent obstacles to a widespread use of ultrafine-grained materials.
