I-Long March 2F Rocket ethwele i-Shenzhou-12 Manned Spacecraft yethulwe ngempumelelo eSikhungweni Sokuqalisa ISathelayithi eJiuquan ngo-9:22 ekuseni ngoJuni 17, okusho ukuthi imboni yezomkhathi yaseChina isithuthuke kakhulu. Kungani i-tungsten ne-molybdenum zenza umnikelo omangalisayo wokwethulwa kweShenzhen-12?

1.Rocket Gas Rudder

I-Tungsten molybdenum alloy material iyisinqumo esingcono kakhulu se-rocket engine gas rudder, ngoba i-rocket engine gas rudder isebenza endaweni eshisa kakhulu kanye ne-corrosion environment. Njengoba sonke sazi, isici se-tungsten ne-molybdenum simelana nezinga lokushisa eliphezulu nokugqwala.

Kokubili i-tungsten ne-molybdenum kuyisakhiwo se-cubic esigxile emzimbeni futhi ama-lattice constants asondelene, ngakho angahlanganiswa ngokushintshanisa nesixazululo esiqinile sibe yingxubevange kanambambili.Uma kuqhathaniswa ne-tungsten emsulwa ne-pure molybdenum, i-tungsten molybdenum alloy ukusebenza okuphelele kungcono, ikakhulukazi ezindlekweni zokukhiqiza namandla aphezulu ekushiseni okuphezulu.

2.Rocket Ignition Tube

I-Tungsten alloy material nayo ilungele ukuthungela injini yerokhethi.Isizathu siwukuthi izinga lokushisa eliphumayo lerokhethi lingaphezu kuka-3000.℃ekwazi ukuncibilikisa insimbi, kanye nengxubevange ye-tungstenIzinzuzo ncamashi ukumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, amandla aphezulu kanye nokumelana nokukhipha umoya okuhle kakhulu.

3.Rocket Throat Bushing

I-rocket bushing, ingxenye yenjini, ukusebenza kwayo kungaba nomthelela ngokuqondile kwikhwalithi ye-booster.igesi uma i-rocket yethulwa emphinjeni ingaveza ukushuba okukhulu, okubangele izinga lokushisa eliphezulu nokucindezela emphinjeni.W-Cu ingxubevange ikhethwa ukuqhuma komphimbo esikhathini samanje, ngoba ingxubevange ye-W-Cu ingamelana nezinga lokushisa eliphakeme namandla omthelela wemishini.

Ngaphandle kwezingxenye ezingenhla zerokhethi, kukhona nezingxenye eziningi ezenziwe ngezinto ze-tungsten ne-molybdenum. Yingakho i-tungsten ne-molybdenum materials yenza umnikelo omangalisayo ekwethulweni kwe-Shenzhen-12.
