Kuyini I-Hot Isostatic Pressing (HIP)?

Uma senza imikhiqizo ye-tungsten carbide, kufanele sikhethe izinto ezingavuthiwe ezinhle kakhulu, i-tungsten carbide powder kanye ne-binder powder, ngokuvamile i-cobalt powder. Hlanganisa futhi uwagaye, uyomisa, ucindezela, futhi u-sintering. Ngesikhathi sokucula, sihlala sinokukhetha okuhlukile. Futhi kulesi sihloko, sizokhuluma ngokucindezela okushisayo kwe-isostatic sintering.

Kuyini I-Hot Isostatic Pressing?

I-Hot Isostatic Pressing, eyaziwa nangokuthi i-HIP, ingenye yezindlela zokucubungula izinto. Ngesikhathi sokucindezela okushisayo kwe-isostatic sintering, kunamazinga okushisa aphezulu nokucindezela kwe-isostatic.

Igesi esetshenziswa ekucindezeleni okushisayo kwe-isostatic sintering

Igesi ye-Argon isetshenziswa ekucindezelweni okushisayo kwe-isostatic sintering. Esithandweni somlilo we-sintering, kunamazinga okushisa aphezulu nokucindezela okukhulu. Igesi ye-Argon kungenzeka ibangele ukuguquguquka okukhulu ngenxa yokuminyana okuphansi kanye ne-coefficient of viscosity, kanye nama-coefficients aphezulu wokunwetshwa kokushisa. Ngakho-ke, ama-coefficients okudlulisa ukushisa kwemishini yokucindezela ye-isostatic eshisayo ephakeme kunaleyo yesithando somlilo esivamile.

Ukusetshenziswa kokucindezela okushisayo kwe-isostatic sintering

Ngaphandle kokukhiqiza imikhiqizo ye-tungsten carbide, kunezinye izinhlelo zokusebenza zokucindezela okushisayo kwe-isostatic sintering.

1. Ukucindezela amandla.

Isb. Ama-Ti alloys enziwa ngokucindezela okushisayo kwe-isostatic sintering ukwenza ingxenye yendiza.

2. Ukuhlanganiswa kokusabalalisa kwezinhlobo ezahlukene zezinto.

Isb. Ukuhlanganiswa kwamafutha enuzi kwenziwa nge-hot isostatic pressing sintering ukuze kusetshenziswe kumareactor enyukliya.

3. Ukususwa kwezimbotshana ezisele ezintweni ezine-sintered.

Isb. I-Tungsten carbide nezinye izinto, njenge-Al203, zenziwa ngokucindezela kwe-isostatic sintering ukuze kuzuze izakhiwo eziphakeme, njengokuqina okuphezulu.

4. Ukususwa kweziphambeko zangaphakathi zokulingisa.

Ama-al kanye nama-superalloys enziwa ngokucindezela kwe-isostatic ngokucindezela ukuze kususwe amaphutha angaphakathi.

5. Ukuvuselelwa kwezingxenye ezilinyazwe ukukhathala noma ukukhasa.

6. Izindlela ze-carbonization ezifakwe ngomfutho ophezulu.

Izinto ezihlukile zokwenziwa ngokucindezela okushisayo kwe-isostatic

Njengoba i-isostatic pressing sintering eshisayo inezinhlelo eziningi kangaka, ingasetshenziswa ukwenza izinhlobo zezinto. Izinto ezihlukene zinezici ezihlukene zomzimba namakhemikhali, ngakho zinezidingo ezihlukene zezimo ze-sintering. Kufanele siguqule izinga lokushisa nokucindezela kwezinto ezihlukahlukene. Isibonelo, i-Al2O3 idinga u-1,350 ukuya ku-1,450°C kanye ne-100MPa, futhi i-Cu alloy icela ama-500 kuya ku-900°C kanye ne-100MPa.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
