Umahluko kwiTungsten Carbide kunye neHSS

I-HSS luhlobo lwesixhobo esisetyenziselwa ukusika i-tungsten carbide, kodwa kukho iiyantlukwano ezininzi phakathi kwezi zinto zimbini. Kweli nqaku, siza kubona umahluko kwisithako sabo sezinto eziphathekayo, ukusebenza kunye nokusetyenziswa.

Isithako sezinto eziphathekayo

Kwizixhobo ezahlukeneyo zesixhobo kunye neenkqubo zokuvelisa, kukho izinto ezahlukeneyo zezinto ezisetyenziselwa ukwenza i-tungsten carbide kunye nentsimbi ephezulu.

Ukuvelisa i-tungsten carbide idinga i-tungsten carbide powder kunye ne-cobalt, i-nickel, okanye i-molybdenum. Ngelixa ukuvelisa isinyithi esinesantya esiphezulu sidinga isigaba sekhabhoni, isigaba se-tungsten, isigaba serubha sekloroprene, kunye nesigaba semanganese.

Ukusebenza

Iimveliso ze-tungsten carbide zenziwe nge-tungsten carbide powder, enendawo yokunyibilika ephezulu kakhulu, efikelela kuma-2800 ℃. Xa abasebenzi besenza iimveliso ze-tungsten carbide, baya kongeza ezinye izibophelelo, njenge-cobalt, i-nickel, kunye ne-molybdenum kwi-tungsten carbide powder. Iya kuba sintered phantsi kwamaqondo obushushu aphezulu kunye noxinzelelo oluphezulu. Emva koko, i-tungsten carbide inokufumana ukusebenza okuhle. Ubunzima babo bufikelela kwi-Mohs ye-9, kuphela ngaphantsi kwedayimane. Ukuzinza kwayo kwe-thermal kujikeleze i-110 W / (m. K), ngoko ke i-tungsten carbide isenokusebenza, naphantsi kobushushu obuphezulu kakhulu. Isantya sokusika i-tungsten carbide siphezulu ngamaxesha angama-7 ngaphezu kwentsimbi ephezulu, enokunceda ukuphucula ukusebenza kakuhle. Kwaye i-tungsten carbide inzima kakhulu kwaye iyaxhathisa kunentsimbi enesantya esiphezulu, ngoko ke i-tungsten carbide inokusebenza ixesha elide. Ngokubhekiselele, ngobulukhuni obuphezulu, i-tungsten carbide inobunzima obuphezulu.

Intsimbi yesantya esiphezulu nayo insimbi yesixhobo, equlethe umxholo ophezulu wekhabhoni. Inobunzima obuphezulu, ukumelana nokunxiba okuphezulu, kunye nokuxhathisa okuphezulu kwe-thermal, kodwa konke okungaphantsi kwe-tungsten carbide. Kwintsimbi enesantya esiphezulu kukho intsimbi, ichromium, itungsten kunye nekhabhoni kuyo. Ke intsimbi enesantya esiphezulu inomgangatho ozinzileyo ngokunjalo. Isinyithi esinesantya esiphezulu asikwazi ukumelana nobushushu obuphezulu njengetungsten carbide. Xa ubushushu bufika kwi-600 ℃, ukuqina kwentsimbi enesantya esiphezulu kuya kuncipha.

Isicelo

Ngokwentsebenzo yabo eyahlukileyo ngexesha lokusebenza, baya kusetyenziselwa izicelo ezahlukeneyo.

I-tungsten carbide isetyenziswa njengamasuntswana e-tungsten carbide drill, izixhobo zemigodi, iindawo zokunxiba i-carbide, imilomo, kunye nomzobo wocingo ziyafa ngenxa yokuba ezi zixhobo ziyafuneka ukuba zinganxibi kwaye zikwazi ukumelana nomhlwa.

I-HSS ifaneleke ngakumbi ukwenza izixhobo zokusika isinyithi, iibheringi kunye nokubumba.

Ukuthelekisa i-tungsten carbide kunye ne-high-speed steel, akunzima ukubona ukuba i-tungsten carbide inezakhiwo ezingcono kunye nendlela yokuvelisa elula.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
