I-carbide enesamente yimathiriyeli yealloyi eyenziwe ngeteknoloji yomgubo wesinyithi. Ubukhulu becala iqulunqwe ziikhompawundi eziqinileyo zeentsimbi eziphikisayo kunye neentsimbi ezibophayo.

Amacandelo aphambili e-carbide enesamente aquka i-refractory carbide powders efana ne-tungsten carbide kunye ne-titanium carbide, kunye ne-powders yensimbi esetyenziswa njengezibophelelo, ezifana ne-cobalt kunye ne-nickel. Esi sixhobo siyaziwa ngobunzima obuphezulu, ukuxhatshazwa kokugqoka, amandla kunye nokuqina, ukuxhathisa ukushisa kunye nokuxhatshazwa kwe-corrosion, ngokukodwa kumaqondo aphezulu okushisa ngelixa ugcina ezi zakhiwo. Ukuqina kunye nokumelana nokunxiba kwe-carbide ene-cemented ayitshintshanga kwi-500 ° C, kwaye isenokugcina ubunzima obuphezulu kwi-1000 ° C. Ke ngoko, isetyenziswa kakhulu kwimveliso yokusika izixhobo, izixhobo zokomba, izixhobo zokulinganisa, iimolds zomsebenzi obandayo kunye neendawo ezahlukeneyo zokunxiba.

Inezi mpawu zilandelayo:

1. Ubunzima obuphezulu: Ubunzima be-carbide enesamente buhlala buphezulu kakhulu kunezinto eziqhelekileyo zetsimbi, okwenza kube nzima ukumelana nokunxiba kunye nokusika. ( Ngokuqhelekileyo phakathi kwe-80HRA-94HRA)

2. Amandla aphezulu: I-Carbide inamandla amakhulu, inokumelana noxinzelelo olukhulu kunye nomthwalo, kwaye akulula ukukhubazeka okanye ukuphuka. (Ngokuqhelekileyo i-TRS phakathi kwe-2000-3200 Mpa )

3. Ukuxhatshazwa kokugqoka: Ngenxa yobunzima bayo obuphezulu, i-carbide inokumelana nokugqwesa okugqwesileyo kwaye ifanelekile kwizicelo ezifuna ukuchasana kwexesha elide.

4. Ukuxhatshazwa kwe-Corrosion: I-Carbide inokuchasana okulungileyo kumajelo amaninzi e-corrosion kwaye inokugcina ukusebenza kwayo kwiindawo ezinzima.

5. Uzinzo oluphezulu lweqondo lokushisa: Inokugcina iimpawu zayo zomzimba kunye neekhemikhali kumaqondo aphezulu kwaye akulula ukuthambisa okanye ukuguqula.

6. Umbane olungileyo kunye ne-thermal conductivity: Enye i-carbide ene-cemented ine-conductivity efanelekileyo yombane kunye ne-thermal, eyenza ibe luncedo kwimimandla ye-electronics kunye nolawulo lwe-thermal.

Ezi zakhiwo zenza i-carbide enesamente isetyenziswe ngokubanzi kwimveliso yezixhobo, umatshini, i-aerospace, i-petrochemical kunye nezinye iindawo. Iindidi ezahlukeneyo ze-carbide zinokuthi zilungele ukuhlangabezana neemfuno ezithile zokusebenza ngokulungelelanisa ukubunjwa kunye neenkqubo zokuvelisa. Nangona kunjalo, iimpawu ezithile zokusebenza zingahluka ngokuxhomekeke ekubunjweni kwe-carbide, isakhiwo kunye nenkqubo yokuvelisa. Kwizicelo eziphathekayo, izinto ezifanelekileyo ze-carbide kufuneka zikhethwe ngokwemiqathango ethile yokusetyenziswa kunye neemfuno.

I-CD carbide iyingcali kwiimveliso ze-tungsten ze-carbide ezifana nenxalenye yokumelana nokunxiba, izixhobo zemigodi, izixhobo zokusika njalo njalo.
