ABSTRACT:
A method for decontaminating and subsequently metallizing a filament comprises:
Passing the filament through the inner tube of a first chamber for decontamination which comprises two concentric tubes having an annular space therebetween, the inner tube of which has a series of fine holes therein; wherein said inner tube is heated and said annular space contains an inert gas such that said gas flows through said holes in heated jet streams which impinge upon said filament, thereby heating and decontaminating said filament;
Passing said heated and decontaminated filament into a second chamber for metallization also comprising two concentric tubes having an annular space therebetween, the inner tube of which has a series of fine holes therein; wherein said inner tube of said second chamber is heated and said annular space of said second chamber contains a gaseous, thermally decomposable metal compound such that said gaseous metal compound flows through said holes in heated jet streams and impinges upon said heated and decontaminated filament, thereby thermally decomposing said metal compound and metallizing said filament. An apparatus for carrying out this method is also provided, a key feature of which is an intermediate chamber communicating with an end of each the first and second chambers and having a thin membrane disposed transversely therein. The wire passes from the decontamination chamber through a pinhold in the membrane and through the metallization chamber.
