Vliv výkonu hořáku a tlaku plynu na vlastnosti RF-ICP wolframových nástřiků

Original language description

Tungsten based materials are currently considered as promising candidates for future fusion reactors, especially for the parts which may be in contact with hot plasma. Even though tungsten has many suitable properties such as high melting point and good thermal conductivity, it has also several drawbacks, namely poor machinability or susceptibility to oxidation at elevated temperatures. These problems can be avoided by choosing appropriate processing methods. One of those could be plasma spraying in vacuum or inert/reducing atmosphere. In our study, a radio frequency inductively coupled plasma (RF-ICP) torch TekSpray-15 (Tekna, Canada), was used to fabricate a set of tungsten coatings in an Ar-H2 reducing atmosphere under varying torch powers and chamber pressures. The influence of these system parameters on the coating properties was studied via XRD analyses and SEM observations of the coating microstructures and free surfaces.
