I-alloy eqinileyo exutywe ne-tungsten carbide

Isishwankathelo

INDAWO: i-metallurgy.

IZINTO: uyilo lunxulumene nentsimi yesinyithi esingumgubo. Ingakumbi inxulumene nokufumana i-alloy eqinileyo exutywe ne-tungsten carbide. Ingasetyenziselwa ukwenza izixhobo zokusika, ii-drill kunye ne-milling cutter. I-alloy eqinileyo iqulethe i-80.0-82.0 wt % tungsten carbide kunye ne-18.0-20.0 wt % yokubopha. Ukubopha kuqulethe, wt %: molybdenum 48.0-50.0; niobium 1.0-2.0; rhenium 10.0-12.0; cobalt 36.0-41.0.

ISIPHUMO: ukufumana i-alloy enamandla aphezulu.

Inkcazo

Olu vumbululo lunxulumene nentsimi ye-powder metallurgy kunye nokuveliswa kwee-alloys ezinzima ezixutywe ne-tungsten carbide, ezinokusetyenziselwa ukwenza izixhobo zokusika, ii-drill, ii-mills kunye nezinye izixhobo.

I-carbide exutyiweyo eyaziwayo esekelwe kwi-tungsten carbide, equlethe i-3.0 ukuya kwi-20.0 wt.% I-alloy ye-binder equlethe, i-wt.%: i-Cobalt 20.0-75.0; i-molybdenum – ukuya kuthi ga kwi-5.0; i-niobium – ukuya kuthi ga kwi-3.0 [1].

Injongo yale mveliso kukwandisa amandla e-alloy.

Isiphumo sobuchwephesha sifumaneka kuba kwi-alloy eqinileyo exutywe ne-tungsten carbide equlethe i-80.0-82.0 wt.% Tungsten carbide kunye ne-18.0-20.0 wt.% Binder, i-binder iqulethe, wt.%: iMolybdenum 48 0-50.0; i-niobium 1.0-2.0, i-rhenium 10.0-12.0; i-cobalt 36.0-41.0.

Kwitheyibhile. 1 ibonisa ukwakheka kwe-alloy, kunye namandla okugqibela ekugobeni. Kwitheyibhile. 2 ibonisa ukwakheka kwe-ligament.

Itheyibhile 1 Izinto ezidityanisiweyo, ubunzima%: inye 2 3 iWolfram carbide 80.0 81.0 82.0 Iqhekeza 20.0 19.0 18.0 Amandla okugoba, iMPa ~ 1950 ~ 1950 ~ 1950

Itheyibhile 2. Ukwakheka kwezixhobo, ubunzima%: inye 2 3 Molybdenum 48.0 49.0 50,0 Niobium 1,0 1,5 2.0 Rhenium 10.0 11.0 12.0 Cobalt 41.0 38.5 36.0

Iipowders ze-alloy components zixutywe ngokwemilinganiselo ebonisiweyo, umxube ucinezelwa phantsi koxinzelelo lwe-4.5-4.8 t / cm2 kwaye utshiswe kwisithando sombane kubushushu be-1300-1330 ° C kwi-vacuum iiyure ezi-7-9. Ngexesha lokutshiza, i-binder inyibilikisa inxalenye ye-tungsten carbide ize inyibilike. Isiphumo sisixhobo esixineneyo esinesakhiwo se-tungsten carbide particles ezidityaniswe yi-binder.
