Hlobo Luni Lwempahla Eyi-Tungsten Steel?

Ukuqina kwensimbi ye-tungsten kungokwesibili kuphela kwedayimane, kodwa ayikwazi ukusetshenziswa njenge-blade yokusetshenziswa okuvamile.

Uma ngikhuluma ngensimbi ye-tungsten, ngikholwa ukuthi abangani abaningi abavamile ukuyizwa. Kodwa uma kuziwa kwelinye igama layo: i-carbide enosimende, wonke umuntu kufanele ajwayelane nayo ngoba kuyadingeka ukubhekana nayo ekukhiqizeni ngomshini. I-carbide enosimende iwukwenziwa okuqinile kakhulu, futhi ingxenye yayo eyinhloko impushana ye-tungsten emnyama ngemva kwe-sintered carbonization.

Ngokwezidingo ezihlukene zomkhiqizo, ukwakheka kwawo kuphakeme njenge-85% kuya ku-97%. Okunye okuqukethwe ikakhulukazi yi-cobalt, i-titanium, ezinye izinsimbi, nezibophezelo. Sivame ukusho ukuthi i-carbide enosimende iyinsimbi ye-tungsten. Ukukhuluma ngokuqinile, insimbi ye-tungsten ingeye-carbide enosimende. I-Tungsten iyinsimbi ekhethekile eminyene enephuzu elincibilikayo eliphakeme kakhulu kanye nokuhamba kahle kukagesi. Ngakho-ke isetshenziswa njenge-filament kagesi kanye ne-electrode ye-argon arc welding. Insimbi ye-Tungsten ibonakala ngokuqina kwayo okuphezulu nokumelana nokugqoka.

Ngisho nasekushiseni okuphezulu kwezinkulungwane zamadigri, insimbi ye-tungsten inobunzima obukhulu. Ukuqina kwensimbi ye-tungsten kungokwesibili kuphela kwedayimane. Eyaziwa ngokuthi izinyo lemboni yesimanje, i-tungsten steel inezinto eziningi ezinhle kakhulu, njengokumelana nokushisa, ukumelana nokugqwala, nokuzinza okuhle. Ngakho-ke, isetshenziswa kakhulu ekukhiqizeni amathuluzi okusika anesivinini esikhulu, njengokubhoboza ompompi, izisiki zokugaya, ama-saw blades, nezimbobo zenjini yerokhethi eshisa kakhulu.

Njengoba ubulukhuni be-Rockwell bensimbi ye-tungsten buphezulu njengo-90HAR, inokuqina okuphansi futhi i-brittle ikakhulukazi. Imikhiqizo yensimbi ye-Tungsten kungenzeka iphuke lapho iwelwa phansi, ngakho-ke insimbi ye-tungsten ayifanele ukusetshenziswa kwansuku zonke kwama-blades. Inqubo yokukhiqiza yensimbi ye-tungsten iyi-powder metallurgy. Okokuqala, i-tungsten powder ehlanganisiwe icindezelwa esikhunjeni bese ishiswa ekushiseni okuthile esithandweni somlilo. Ngemuva kokupholisa, i-tungsten steel blank edingekayo iyatholakala. Ngemva kokusika nokugaya, umkhiqizo ophelile uyaphuma. Ngokuthuthukiswa kwezinto ezintsha nobuchwepheshe, amazwe amaningi athuthukisa ama-superalloy amasha, futhi insimbi ye-tungsten iyinsimbi ethakazelisa kakhulu kwezesayensi yezinto zesimanje kanye nokusansimbi, kanti insimbi ye-tungsten nayo isiba into ebaluleke kakhulu kuma-alloys. Ngakho-ke, kungenzeka ukuthuthukisa ama-alloys amasha anamandla ngokusebenzisa izakhiwo ezikhethekile zensimbi ye-tungsten.

Uma uthanda imibhobho eqhumayo noma ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele noma SITHUMELE IMEYILI ezansi nekhasi.
