Stranded Tungsten Hlau Rau Nqus Metallizing
Cov nkoj tungsten, pob tawb thiab filaments yog tsim los ntawm qib siab tungsten.Ntawm tag nrho cov hlau nyob rau hauv daim ntawv ntshiab, tungsten muaj qhov siab tshaj plaws melting point (3422 ° C / 6192 ° F), qis tshaj vapor siab ntawm qhov kub siab tshaj 1650 ° C (3000 ° F) thiab muaj lub zog tensile siab tshaj plaws.Tungsten kuj muaj qhov qis tshaj coefficient ntawm thermal expansion ntawm tej yam hlau ntshiab.Qhov kev sib xyaw ua ke ntawm cov khoom no ua rau tungsten yog cov khoom siv zoo tshaj plaws rau evaporation qhov chaw.Thaum lub sij hawm evaporation, nws tuaj yeem alloy nrog qee cov ntaub ntawv xws li Al lossis Au.Hauv qhov no, lwm cov khoom siv evaporation yuav tsum tau siv xws li alumina coated nkoj lossis pob tawb.Lwm cov ntaub ntawv muaj txiaj ntsig zoo rau cov evaporation yog molybdenum thiab tantalum.
