Ingabe i-tungsten carbide ayinakonakala ngempela?

I-carbide enosimendeinobunzima obuphakeme kakhulu, ngokuvamile phakathi kwe-HRA80 ne-HRA95 (ukuqina kwe-Rockwell A).Lokhu kungenxa yokuthi ingxenye ethile ye-cobalt, i-nickel, i-tungsten nezinye izakhi zengezwa ku-carbide enosimende, okwenza kube nokumelana nokugqoka okuphezulu kakhulu nobulukhuni.Izigaba ezinzima eziyinhloko ku-carbide enosimende i-tungsten carbide (WC) ne-tungsten carbide cobalt (WC-Co), phakathi kwayo ubulukhuni be-WC buphezulu kakhulu, bulukhuni kunedayimane.I-cobalt entweni ye-WC-Co ingathuthukisa ukuqina nokumelana nokugqwala kwezinto.Kumele kuqashelwe ukuthi ubulukhuni be-carbide enosimende buhlobene nokwakheka kwamakhemikhali, inqubo yokulungiselela, ukuminyana kwe-block kanye nezinye izici, futhi ubulukhuni bezinhlobo ezahlukene ze-carbide enosimende kungase kuhluke.

I-carbide enosimende inokuqina okuphezulu nokumelana nokugqoka, futhi ivame ukusetshenziselwa ukusika izinto nokwenza amathuluzi.Kodwa akuzona zonke izinto ezingasetshenziswa kalula noma zicutshungulwe nge-carbide, futhi kukhona ukulinganiselwa okuthile.Isibonelo, ukusebenza kokusika kweamathuluzi e-carbidezingahluka lapho usika izinhlobo ezahlukene zensimbi.

Lapho usika izinsimbi eziqinile, amathuluzi e-carbide ngokuvamile adinga ukumbozwa okukhethekile noma imiklamo yejometri ukuze kugcinwe ukusebenza kwawo kokusika.Ngesikhathi esifanayo, amathuluzi e-carbide enosimende awakwazi ukusika izinto eziphukayo kakhulu, njengengilazi nezitsha zobumba.Ngakho-ke, i-carbide enosimende ayikho ngokuphelele ngaphandle kokulinganiselwa.Idinga ukusetshenziswa ezimweni ezithile zohlelo futhi idinga ukuthuthukiswa ngokuhlanganiswa nezinye izinto noma izindlela zokuklama.
