Umehluko ku-Tungsten Carbide ne-HSS

I-HSS iwuhlobo lwethuluzi elisetshenziswa ukusika i-tungsten carbide, kodwa kunomehluko omningi phakathi kwalezi zinto ezimbili. Kulesi sihloko, sizobona umehluko kwisithako sabo esibonakalayo, ukusebenza, nokusebenza.

Isithako esibalulekile

Okwezinto ezisetshenziswayo ezahlukahlukene kanye nezinqubo zokukhiqiza, kunezithako zezinto ezibonakalayo ezahlukahlukene ezisetshenziselwa ukwenza i-tungsten carbide nensimbi enesivinini esikhulu.

Ukukhiqiza i-tungsten carbide kudinga i-tungsten carbide powder ne-cobalt, i-nickel, noma i-molybdenum. Ngenkathi ukukhiqiza insimbi enesivinini esikhulu kudinga isigaba sekhabhoni, isigaba se-tungsten, isigaba senjoloba ye-chloroprene, nesigaba semanganese.

Ukusebenza

Imikhiqizo ye-tungsten carbide yenziwe nge-tungsten carbide powder, enendawo yokuncibilika ephezulu kakhulu, efinyelela cishe ku-2800 ℃. Lapho izisebenzi zakha imikhiqizo ye-tungsten carbide, zizofaka ezinye izibophezelo, njenge-cobalt, i-nickel, ne-molybdenum kumpushana we-tungsten carbide. Izocwiliswa ngaphansi kwamazinga okushisa aphezulu kanye nengcindezi ephezulu. Ngemuva kwalokho, i-tungsten carbide ingathola ukusebenza okuhle. Ukuqina kwabo kufinyelela ku-Mohs ye-9, ngaphansi kwedayimane kuphela. Ukuzinza kwayo okushisayo kucishe kube ngu-110 W/(m. K), ngakho-ke i-tungsten carbide isengasebenza, ngisho nangaphansi kwamazinga okushisa aphezulu kakhulu. Ijubane lokusika le-tungsten carbide liphakeme izikhathi ezingu-7 kunelensimbi enesivinini esikhulu, elingasiza ukuthuthukisa ukusebenza kahle. Futhi i-tungsten carbide inzima kakhulu futhi imelana kakhulu kunensimbi enesivinini esikhulu, ngakho-ke i-tungsten carbide ingasebenza isikhathi eside. Ngokuqhathaniswa, ngobulukhuni obuphakeme, i-tungsten carbide inokuqina okuphezulu.

Insimbi enesivinini esikhulu nayo iyinsimbi yamathuluzi, equkethe okuqukethwe okuphezulu kwekhabhoni. Inobunzima obuphezulu, ukumelana nokugqoka okuphezulu, nokumelana nokushisa okuphezulu, kodwa konke kungaphansi kwe-tungsten carbide. Ensimbi enesivinini esikhulu, kukhona i-iron, i-chromium, i-tungsten, ne-carbon kuyo. Ngakho-ke insimbi enesivinini esikhulu inekhwalithi ezinzile nayo. Insimbi enesivinini esikhulu ayikwazi ukumelana namazinga okushisa aphezulu njenge-tungsten carbide. Lapho izinga lokushisa lifika ku-600 ℃, ubulukhuni bensimbi enesivinini esikhulu buzokwehla.

Isicelo

Ngokusho kokusebenza kwazo okuhlukile ngesikhathi sokusebenza, zizosetshenziselwa izinhlelo zokusebenza ezahlukene.

I-Tungsten carbide isetshenziswa njengezingcezu zokumba i-tungsten carbide, amathuluzi ezimayini, izingxenye ezigqokwayo ze-carbide, imibhobho, kanye nokudweba kwezintambo kuyafa ngoba la mathuluzi adingeka ukuthi angagugi futhi amelane nokugqwala.

I-HSS ifaneleka kakhulu ekwenzeni amathuluzi okusika insimbi, ama-bearings, kanye nesikhunta.

Ukuqhathanisa i-tungsten carbide nensimbi enesivinini esikhulu, akunzima ukubona ukuthi i-tungsten carbide inezakhiwo ezingcono kanye nendlela yokukhiqiza elula.

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