Fa'aoga fanua o tungsten

Tungsten e lauiloa foi o le wolfram, o se elemene elemene ma le faailoga o le W ma le numera atomic o le 74. O se uʻamea tulaga ese lea e iai le tele o faʻaoga i tekinolosi faʻaonaponei. u'amea u'amea o se u'amea malo ma seasea. E mafai ona maua i luga o le fogaeleele i vailaʻau faʻapitoa. O le tele o ana vailaʻau faʻapitoa o le tungsten oxide ma o le tele o mines tungsten na maua i Saina. Ae maise i itumalo o Hunan ma Jiangxi. Ona o le maualuga o le liusuavai, maualuga le maaa, sili ona lelei o le corrosion, lelei eletise eletise, ma le vevela, ua avea ma se tasi o mea e sili ona taua i galuega faʻaonaponei. E faʻaaogaina lautele i mea faʻapipiʻi, eletise, vailaʻau, fomaʻi, ma isi matāʻupu.

1. I le tulaga o Alamanuia Alamanuia

Powder metallurgy o le auala e gaosia ai oloa sintered tungsten. Tungsten paʻu o le mea sili ona taua mata ma le amataga o oloa tungsten minerale. O le pauta tungsten e faia e ala i le taoina ma le faʻamafanafanaina o le tungsten oxide i totonu o le ea hydrogen. O le mama, okesene, ma le lapopoa o vaega e taua tele mo le saunia o le paʻu tungsten. E mafai ona faʻafefiloi ma isi paʻu elemene e fai ai ituaiga tungsten alloys.

Tungsten carbide-fa'avae sima carbide:

Tungsten carbide e masani ona faʻaaogaina e faʻafefiloi ma isi metala e faʻaleleia ai lona faʻatinoga. O mea faʻafefiloi e aofia ai cobalt, titanium, uʻamea, siliva, ma tantalum. O le taunuuga o le carbide sima faʻavae tungsten carbide e maualuga atu le ofuina o le teteʻe ma maualuga atu meatotino refractory. E masani ona faʻaaogaina i le gaosiga o meafaigaluega tipi, mea faigaluega eli, uaea tusi oti, ma isi. Tungsten carbide-faʻavae sima carbide oloa e sili atu nai lo uʻamea uʻamea ona o lo latou faigata tele ma le tetee i le ofuina ma loimata. E mafai ona fa'aaogaina lautele i fa'atauga faufale fa'atau, mea fa'aeletonika, mea fa'atauga tau alamanuia, mea e fa'asalaina ai mea fa'avevela, ma le alamanuia ea.

u'amea fa'afefete ma fa'alavalava:

O le mea faʻafefeteina o le tungsten e sili ona maualuga i uʻamea uma, ma o lona maʻaʻa e lona lua i le taimane. O lea e masani ona faʻaaogaina e gaosia ai mea faʻafefe vevela ma faʻafefe. Mo se faʻataʻitaʻiga, Alloys of tungsten ma isi metals refractory (tantalum, molybdenum, hafnium) e masani ona gaosia vaega malosi-maualuga e pei o nozzles ma afi mo rockets. Ma o mea faʻapipiʻi o le tungsten, chromium, ma le carbon e masani ona faʻaaogaina e gaosia ai vaega maualuga-malosi ma ofuina, e pei o valve mo afi vaalele, uili turbine, ma isi.

2. I le tulaga o vailaau

Tungsten compounds e masani ona faʻaaogaina e gaosia ai nisi ituaiga o vali, vaitusi, lubricants, ma catalysts. Mo se faʻataʻitaʻiga, o le tungsten oxide lanu apamemea e faʻaaogaina i le valiina, ma o le calcium poʻo le magnesium tungsten e masani ona faʻaaogaina i phosphors.

3. I le matata o le militeli

Tungsten oloa ua faʻaaogaina e sui ai le taʻitaʻia ma faʻaumatia mea uranium e fai ai pulufana faʻaulu ona o latou mea e le oona ma le puipuiga o le siosiomaga, ina ia faʻaitiitia ai le faʻaleagaina o mea a le militeri i le siʻosiʻomaga. E le gata i lea, e mafai e le tungsten ona sili atu le taua o oloa a le militeri ona o lona malosi malosi ma le lelei o le maualuga o le vevela.

Tungsten e mafai ona faʻaaogaina e le gata i luga o fanua ae faʻapea foʻi i faʻasalalauga, malosi atomika, fau vaa, fale gaosi oloa, ma isi fanua. Afai e te fiafia i le tungsten pe iai ni fesili e uiga i ai. Fa'amolemole fa'afeso'ota'i mai nei.
