Isikrufu se-SiC Axle

Inkcazo:

I-Silicon Carbide ineempawu zokuxhathisa kakuhle - ukubola, amandla aphezulu oomatshini, ukuqhuba okuphezulu kobushushu, ukuzithambisa okuhle okusetyenziswa njengee-seal faces, ii-bearings kunye nee-tubes kwi-spacecraft, oomatshini, i-metallurgy, ukushicilela kunye nokudaya, ukutya, amayeza, ishishini leemoto njalo njalo. Xa ii-sic faces zidityaniswe nee-graphite faces, ukungqubana kuba kuncinci kwaye kunokwenziwa zibe zii-mechanical seals ezikwaziyo ukusebenza kwiimfuno eziphezulu zokusebenza.

Iipropati eziSiseko zeSilicon Carbide:

-Uxinano oluphantsi

-Ukuqhuba okuphezulu kobushushu (kufutshane ne-aluminium)

-Ukumelana okuhle nokutshiswa kobushushu

-Ulwelo kunye negesi azinabungozi

-Ukungaguquguquki okuphezulu (kungasetyenziswa kwi-1450℃ emoyeni kunye ne-1800℃ kwindawo engathathi hlangothi)

-Ayichaphazeleki kukugqwala kwaye ayimanzisi nge-aluminium enyibilikisiweyo okanye i-zinc enyibilikisiweyo

-Ubulukhuni obuphezulu

-I-coefficient yokungqubana okuphantsi

-Ukumelana nokurhawuzelelwa

-Imelana nee-asidi ezisisiseko nezinamandla

-Iyapholishwa

-Unamandla aphezulu oomatshini

Isicelo seSilicon Carbide:

-Iimpawu zoomatshini, iibheringi, iibheringi zokutyhala, njl.

-Amalungu ajikelezayo

-I-Semiconductor kunye ne-coating

-IiPads Izinto zePump

-Izinto zekhemikhali

-Izibuko zeenkqubo zelaser zoshishino.

- Iireactors ezihamba rhoqo, ii-heat exchangers, njl.

Uphawu

I-silicon carbide yenziwa ngeendlela ezimbini:

1) I-silicon carbide engenaxinzelelo

Emva kokuba izinto ze-silicon carbide ezingenanto ixinzelelweyo zikroliwe, umzobo wesigaba sekristale phantsi kwe-200X optical microscope ubonisa ukuba usasazo kunye nobukhulu beekristale ziyafana, kwaye eyona kristale inkulu ayidluli kwi-10μm.

2) I-silicon carbide exutywe ne-reaction

Emva kokuba i-silicon carbide e-sintered isabela kwiikhemikhali, iphatha icandelo elithe tyaba neligudileyo lezinto, i-crystal
usasazo kunye nobukhulu obuphantsi kwe-200X optical microscope ziyafana, kwaye umxholo we-silicon wasimahla awudluli kwi-12%.
