Yenziwa njani itungsten yobhedu?

I-tungsten yobhedu yenziwa ngenkqubo ebizwa ngokuba yi-infiltration. Kule nkqubo, i-tungsten powder ixutywe kunye ne-binder material ukwenza umzimba oluhlaza. I-compact iye itshiswe ukwenza i-tungsten skeleton ene-porous. I-skeleton ye-tungsten ene-porous ke ifakwe nge-copper etyhidiweyo phantsi kobushushu obuphezulu kunye noxinzelelo. Ubhedu luzalisa ii-pores ze-tungsten skeleton ukuze zenze izinto ezidibeneyo ezineempawu ze-tungsten kunye nobhedu.

Inkqubo yokungena iyakwazi ukuvelisa i-tungsten yobhedu kunye neengqungquthela ezahlukeneyo kunye neempawu, okwenza ukuba zilungele uluhlu olubanzi lwezicelo ezifana noqhagamshelwano lombane, i-electrodes kunye ne-heat sinks.

Ipleyiti yobhedu yeTungsten

I-Copper-tungsten isetyenziswe kwiintlobo ezahlukeneyo zezicelo ngenxa yokudibanisa kwayo okukhethekileyo kweempawu. Olunye usetyenziso oluqhelekileyo lubandakanya:

1. Uqhagamshelwano lombane: I-tungsten ye-Copper isetyenziswa ngokuqhelekileyo kuqhagamshelwano lombane kwi-voltage ephezulu kunye nezicelo eziphezulu zangoku ngenxa yombane ogqwesileyo kunye ne-thermal conductivity, kunye nokumelana ne-arc kunye nokumelana nokugqoka.

2. I-Electrode: Ngenxa yomgangatho wayo ophezulu wokunyibilika, ukuhanjiswa kakuhle kwe-thermal, kunye nokumelana nokubola, isetyenziswe kwi-electrodes ye-welding ye-resistance, i-EDM (i-electrical discharge machining) i-electrodes, kunye nezinye izicelo zombane kunye ne-thermal.

3. I-Aerospace kunye noKhuseleko: Ubhedu lwe-Tungsten lusetyenziswa kwi-aerospace kunye nemboni yokukhusela kwi-rocket nozzles, uqhagamshelwano lombane kwinqwelomoya, kunye nezinye izinto ezifuna amandla aphezulu, ukumelana nokunxiba, kunye ne-thermal conductivity.

4. I-Heat sink: Isetyenziswe njengendawo yokutshisa ubushushu kwisixhobo sombane ngenxa ye-conductivity ephezulu ye-thermal kunye nokuzinza kwe-dimensional.

I-Tungsten ixhathisa kakhulu kumhlwa kunye nokuhlwa. Ngenxa yokungabikho kwayo, i-tungsten ayiyi kuxilisa okanye igxume phantsi kweemeko eziqhelekileyo. Le propati yenza i-tungsten ibe yinto exabisekileyo kwizicelo apho ukuxhatshazwa kwe-corrosion kubaluleke kakhulu.

Ubhedu lweTungsten lwaziwa ngobulukhuni bayo obuphezulu. Ubunzima bobhedu be-tungsten bunokwahluka ngokuxhomekeka kwindlela ethile yokubunjwa kunye neemeko zokucubungula, kodwa ngokubanzi, kunzima kakhulu kunobhedu olucocekileyo ngenxa yobukho be-tungsten. Le propati yenza ubhedu lwe-tungsten lufanelekile kwizicelo apho ukuxhatshazwa kokugqoka kunye nokuqina kubalulekile. Ukuqina kobhedu lwe-tungsten buyenza ilungele ukusetyenziswa kunxibelelwano lombane, i-electrode, kunye nezinye izinto ezifuna ukuxhathisa ukunxiba.
