I-China W90Cu10 ibha yobhedu ye-tungsten yoMvelisi we-EDM kunye noMboneleli

I-W90Cu10 ibha yobhedu ye-tungsten ye-EDM

Ibha yobhedu ye-W90Cu10 ye-tungsten ye-EDM Umfanekiso obonakalayo

Inkcazelo emfutshane:

Ukubunjwa kwe-W90Cu10 kubonisa ukuba intonga yenziwe nge-90% ye-tungsten kunye ne-10% yobhedu. Olu luhlu lubonelela ngeepropati eziyimfuneko kwizicelo ze-EDM, ezifana nobunzima obuphezulu kunye ne-thermal conductivity. Umxholo we-tungsten unceda ukunyusa ubunzima bezinto eziphathekayo kunye nokunganyangeki, ngelixa ubhedu luphucula umbane kunye ne-thermal conductivity.

Ngaba unako i-EDM i-tungsten yobhedu?

Ewe, i-tungsten yobhedu ingasetyenziswa njengesixhobo se-electrode kwi-electrical discharge machining (EDM). I-Copper-tungsten yinto edibeneyo eyenziwe ngobhedu kunye ne-tungsten, ene-conductivity egqwesileyo yombane kunye ne-thermal, indawo ephezulu yokunyibilika kunye nokunganyangeki kakuhle. Ezi zakhiwo zenza ukuba zilungele izicelo ze-EDM.

Xa usebenzisa i-electrodes ye-copper-tungsten ye-EDM, kubalulekile ukuqwalasela izinto ezifana nokubunjwa okuthe ngqo kwezinto ze-copper-tungsten, uhlobo lwempahla yokusebenza eyenziwa ngoomatshini, kunye neeparitha ze-EDM ezifana nokukhutshwa kwangoku, ubude be-pulse, kunye neemeko zokucoca. Ukukhethwa ngokufanelekileyo kunye nokusekwa koomatshini be-EDM nako kubalulekile ukufezekisa iziphumo ezifunwayo zomatshini.

Ngokubanzi, i-tungsten yobhedu yinto esebenzayo kwaye isetyenziswa ngokuqhelekileyo i-EDM ye-electrode, ngokukodwa kwizicelo ezifuna ukumelana nokunxiba okuphezulu kunye ne-thermal conductivity.

Yintoni ukuqina kobhedu lwe-tungsten?

Ubunzima be-tungsten-copper composites bunokwahluka ngokuxhomekeka kwindlela ethile yokubunjwa kunye nendlela yokucubungula. Ngokuqhelekileyo, ii-alloys zobhedu ze-tungsten zinobunzima obuphezulu, zibenza zilungele izicelo apho ukuxhatshazwa kunye namandla kubalulekile.

Ukuqina kobhedu lwe-tungsten ngokuqhelekileyo kulinganiswa kusetyenziswa isikali sobunzima be-Rockwell okanye i-Vickers. I-Tungsten-copper composite zinexabiso lobulukhuni ukusuka kwi-70 HRC (i-Rockwell C) ukuya ngaphezulu kwe-90 HRC, ebonisa ukuxhathisa okuphezulu kwi-deformation kunye nokunxiba.

Ubunzima be-tungsten yethusi buyenza ibe yinto efanelekileyo kwiintlobo ezahlukeneyo zezicelo ezifunwayo, kubandakanywa uqhagamshelwano lombane, i-electrodes ye-welding kunye ne-EDM electrodes, apho izinto zixhomekeke kumatshini ophezulu kunye noxinzelelo lwe-thermal.

Ngaba i-tungsten inobunzima obuphezulu?

Ewe, i-tungsten yaziwa ngobulukhuni bayo obugqithisileyo. Ngapha koko, i-tungsten inamandla aphakamileyo okuqina kwayo nayiphi na intsimbi esulungekileyo kwaye yaziwa ngobulukhuni bayo obukhethekileyo kunye nokunganyangeki. Oku kwenza kube yinto exabisekileyo kunye noluhlu olubanzi lwezicelo, kubandakanywa izixhobo zokusika, izicelo zokushisa eziphezulu kunye namacandelo afuna ukuxhathisa okuphezulu.
