Isabelo esinzima esinzima kwisiseko se-tungsten carbide

Nqabile

Intsimi: I-MetalArgergy.

Isixhobo: Umlo uhambelana nentsimi ye-power ye-power. Ngokukodwa inxulumene nokufumana isabelo esinzima esinzima kwisiseko se-tungsten carbide. Ingasetyenziselwa ukwenziwa kweendawo zokusika, ukuqhuba kunye nokusika i-Milling. I-Hardy Alloty iqulethe i-80.0-82.0 i-wt% ye-tungsten ye-tungsten kunye ne-180 ukuya kwi-20.0 ye-WT% yokubopha. Ukubopha okuqulathe, i-WT%: i-molybdenum 48.0-50.0; I-Niobium 1.0-2.0; I-Rhenium 10.0-12.0; Cobalt 36.0-41.0.

Isiphumo: Ukwamkela amandla amakhulu.

Inkcazo

Umlo unxulumene necandelo le-powder ye-powder kunye nokuveliswa kwee-alloys ezinzima ezikhoyo esekwe kwi-tungsten ye-tungsten, enokusetyenziselwa ukwenziwa kweendawo zokusika, ukuqhuba, ii-mills kunye nezinye izixhobo.

I-carbide eyaziwayo esekwe kwi-tungsten carbide, equkethe i-3.0 ukuya kwi-20.0 wt. molybdenum-ukuya kuthi ga kwi-5.0; I-Niobium-ukuya kwi-3.0 [1].

Injongo yokuyilwa kukwandisa amandla e-alloy.

Iziphumo zobugcisa zifezekisiwe kuloo nto isabelo esinqabileyo se-tungsten ene-80.0-82.0 wt. I-Wt.% Wt. I-Niobium 1.0-2.0, i-Rhenium 10.0-12.0; Cobalt 36.0-41.0.

Kwitafile. 1 ibonisa ukwakhiwa kwe-alloy, kunye namandla aphezulu xa egoba. Kwitafile. 2 ibonisa ukwakhiwa kwe-ligament.

Itheyibhile ye-1, i-WT. I-WT.

Itheyibhile 2. Izinto ezenziwayo, i-WT.

Iipowuni zamacandelo obu-Alalty zixutywe kwinqaku elibonisiweyo, umxube ucinezelwa phantsi koxinzelelo lwe-4.5-4.8 t / cm 2 kunye neqondo lokushisa kwiqondo le-1300-130 ° C kwi-vacuum iiyure ezingama-7-9. Ngexesha lokuqina, i-binder inyibilikisa inxenye ye-carbide ye-tungsten kunye neenyibiba. Isiphumo sezinto ezinobunzima kwezona ndawo zeqhinga eliququzelela amasuntswana e-tungsten exhunyiwe ngumthi.
