Melting Refining Mechanisms in Supersonic Atmospheric Plasma Spraying

Plasma Chemistry and Plasma Processing, 2012
In recent years, Yttria-stabilized zirconia based thermal barrier coatings (TBCs) are deposited by newly-developed high-efficiency supersonic atmospheric plasma spraying (SAPS) technology. The final microstructure of the plasma-sprayed coatings is strongly dependent on the size distribution of spray particles.

Microstructure and laser irradiation characteristics of TiC-free and TiC-doped tungsten-based coatings prepared by supersonic atmospheric plasma spraying

Surface & Coatings Technology, 2019
Tungsten-based coatings without TiC addition (TiC-free) and with 1.5 wt% TiC addition (TiC-doped) were fabricated by supersonic atmospheric plasma spraying (SAPS) technique, respectively. The as-sprayed coatings were then irradiated by laser. The results

Aging of atmospherically plasma sprayed chromium evaporation barriers

Surface and Coatings Technology, 2016
Abstract Chromium evaporation barriers are frequently used in solid oxide fuel cells to protect the porous cathode from chromium poisoning. Volatile chromium species are generated at the operation temperature of about 600–900 °C in a humid atmosphere for chromia scale forming steels as interconnect materials.

Atmospheric pressure plasma jet for liquid spray treatment

Journal of Physics D: Applied Physics, 2016
Atmospheric pressure plasma jets have been intensively studied in recent years due to growing interest in their use for biomedical applications and surface treatments. Either surfaces can be treated by a plasma jet afterglow for cleaning or activation or a material can be deposited by a reactive gas component activated by plasma.

Microwave plasma at atmospheric pressure for thermal spray technology

IEEE Conference Record - Abstracts. 2002 IEEE International Conference on Plasma Science (Cat. No.02CH37340), 2003
Summary form only given, as follows. Recent developments in "cold" and microwave thermal spraying allow the coating process to be considered for many different applications with a wide range of coatings and substrates. This project will investigate the use of an atmospheric microwave plasma, at 2.46GHz frequency, for preheat gases and coating powders ...
