Despite having many advantages (the highest melting point of all metals, high density, low vapor pressure), tungsten also possesses several drawbacks, such as poor machinability and weldability. One of the nowadays considered PFC production routes is plasma spraying. For this, the conventional gas-stabilized atmospheric plasma torches have inherent critical limitations (insufficient plasma enthalpy to efficiently melt the tungsten particles, susceptibility to oxidation at elevated temperatures). The novel radio frequency inductively coupled plasma (RF-ICP) is a unique system capable of overcoming these limitations. Using RF-ICP, more efficient melting of tungsten particles and controlled atmosphere provide a unique possibility to produce dense, oxides-free deposits.
In our study, TekSpray-15 RF-ICP (Tekna, Canada) was used for the preparation of tungsten coatings from two different feedstock powders under varying system parameters (torch power, chamber pressure). Their influence was studied via SEM observations of the deposits microstructure as well as XRD analyses.Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2019 Elektronická adresa http://www.nss.si/nene2018/Contents.htm
