Umuyoboro wa Tungsten uhagaze kuri Vacuum Metallizing

Ibisobanuro bigufi:

Ubwato bwa tungsten, ibitebo hamwe na filaments bikozwe muri tungsten yo mu rwego rwo hejuru.Mu byuma byose muburyo bwera, tungsten ifite aho ishonga cyane (3422 ° C / 6192 ° F), umuvuduko mwinshi wumuyaga mwinshi mubushyuhe buri hejuru ya 1650 ° C (3000 ° F) kandi ufite imbaraga nyinshi.Tungsten ifite kandi coefficient yo hasi yo kwagura ubushyuhe bwicyuma icyo aricyo cyose.Uku guhuza imitungo bituma tungsten ibikoresho byiza byamasoko.Mugihe cyo guhumeka, irashobora kuvanga nibikoresho bimwe nka Al cyangwa Au.Muri iki gihe, hagomba gukoreshwa ikindi kintu gituruka kumyuka nkubwato bwa alumina cyangwa ibiseke.Ibindi bikoresho bifite akamaro ko guhumeka ni molybdenum na tantalum.

Umugozi wa tungsten uhagaze ukoreshwa mugukora ibintu bishyushya nibindi bikoresho bishyushya muri semicomductou nibikoresho bya vacuum.

Umugozi wa tungsten uhagaze ushyirwa mubikorwa nka moteri (gushyushya ibintu) muri vacuum metallizing (evaporation).

Porogaramu

Heating Resistors ikoreshwa nkibikoresho byo gushyushya kugirango isahure insimburangingo ya kinescope, indorerwamo, plastiki, ibyuma nudushusho dutandukanye. Insinga zahagaritswe zikoreshwa nkibikoresho fatizo byo gushyushya ibintu, kandi nkibikoresho byo gushyushya igice cya semiconductor hamwe nibikoresho bya vacuum mu buryo butaziguye.
