I-carbide enosimende iyingxubevange eyenziwe ngobuchwepheshe be-powder metallurgy. Ikakhulukazi yakhiwe izinhlanganisela eziqinile zezinsimbi eziphikisayo nezinsimbi ezibophayo.

Izingxenye eziyinhloko ze-carbide enosimende zihlanganisa izimpushana ze-carbide eziphikisayo ezifana ne-tungsten carbide ne-titanium carbide, kanye nezimpushana zensimbi ezisetshenziswa njengezibophezelo, njenge-cobalt ne-nickel. Le nto iyaziwa ngobulukhuni bayo obukhulu, ukumelana nokugqoka, amandla nokuqina, ukumelana nokushisa nokumelana nokugqwala, ikakhulukazi emazingeni okushisa aphezulu ngenkathi kugcinwa lezi zakhiwo. Ukuqina nokuqina kokuqina kwe-carbide enosimende empeleni akushintshile ku-500 ° C, futhi isengagcina ubulukhuni obuphezulu ku-1000 ° C. Ngakho-ke, isetshenziswa kabanzi ekukhiqizeni amathuluzi okusika, amathuluzi okumba, amathuluzi okulinganisa, isikhunta somsebenzi obandayo kanye nezingxenye ezihlukahlukene ezingagugi.

Inezici ezilandelayo eziyisisekelo:

1. Ukuqina okuphezulu: Ukuqina kwe-carbide enosimende ngokuvamile kuphakeme kakhulu kunokwezinto zensimbi ezejwayelekile, okwenza ukuthi imelane ngempumelelo nokugqokwa nokusikwa. (Ngokujwayelekile phakathi kuka-80HRA-94HRA)

2. Amandla aphezulu: I-Carbide inamandla amakhulu, ingakwazi ukumelana nokucindezela okukhulu nomthwalo, futhi akulula ukuyikhubaza noma ukuphuka. (Ngokujwayelekile i-TRS phakathi kuka-2000-3200 Mpa)

3. Ukumelana nokugqoka: Ngenxa yokuqina kwayo okuphezulu, i-carbide inokumelana nokugqoka okuhle kakhulu futhi ifanele izicelo ezidinga ukumelana nokugqoka isikhathi eside.

4. Ukumelana nokugqwala: I-Carbide inokumelana kahle nemithombo yezindaba edlayo futhi ingagcina ukusebenza kwayo ezindaweni ezinokhahlo.

5. Izinga lokushisa eliphakeme lokuzinza: Ingakwazi ukugcina izici zayo ezibonakalayo namakhemikhali emazingeni okushisa aphezulu futhi akulula ukuthambisa noma ukukhubazeka.

6. Ukuhamba kahle kukagesi kanye ne-thermal: Enye i-carbide enosimende ine-conductivity enhle kagesi ne-thermal, okuyenza ibe wusizo emkhakheni wezogesi kanye nokuphathwa kwe-thermal.

Lezi zakhiwo zenza i-carbide enosimende isetshenziswe kabanzi ekwakhiweni kwamathuluzi, ukwenziwa kwemishini, i-aerospace, i-petrochemical neminye imikhakha. Izinhlobo ezahlukene ze-carbide zingenziwa ngendlela efanele ukuhlangabezana nezidingo ezithile zokusebenza ngokulungisa ukwakheka kanye nezinqubo zokukhiqiza. Kodwa-ke, izici ezithile zokusebenza zingahluka kuye ngokuthi ukwakheka kwe-carbide, ukwakheka kanye nenqubo yokukhiqiza. Ekusetshenzisweni okungokoqobo, izinto ezifanele ze-carbide zidinga ukukhethwa ngokuvumelana nezimo ezithile zokusetshenziswa kanye nezidingo.

I-CD carbide inguchwepheshe emikhiqizweni ye-tungsten carbide efana nengxenye yokumelana nokugqoka, amathuluzi okumba, amathuluzi okusika nokunye.
