Uxinaniso oluphezulu, ukubumbeka okugqwesileyo kunye nokusebenza kakuhle, ukumelana nokugqwesa okugqwesileyo, imodyuli ephezulu yokuqina, ukuhanjiswa kwe-thermal okuchukumisayo kunye nokwandiswa kwe-thermal ephantsi. Sibonisa: ii-alloys zethu ze-tungsten zentsimbi enzima.
"Ubunzima" bethu busetyenziswa, umzekelo, kwimizi-mveliso yeenqwelomoya kunye ne-aerospace, iteknoloji yezonyango, imizi-mveliso yeemoto kunye ne-Foundry okanye ukombiwa kwe-oyile negesi. Makhe sibonise ezintathu kwezi zilandelayo:
Ingxubevange yethu ye-tungsten yentsimbi enzima i-W-Ni-Fe kunye ne-W-Ni-Cu inoxinano oluphezulu kakhulu (17.0 ukuya kwi-18.8 g/cm3) kwaye ibonelela ngokhuselo oluthembekileyo ngokuchasene ne-X-reyi kunye nemitha ye-gamma. Zombini i-W-Ni-Fe kunye nezinto zethu ezingenamagnetic i-W-Ni-Cu zisetyenziselwa ukukhusela umzekelo kwisicelo sonyango kodwa nakwishishini leoli kunye negesi. Njengee-collimators kwizixhobo zonyango lwe-radiation baqinisekisa ukuvezwa okuchanekileyo. Xa silinganisa iintsimbi sisebenzisa ingxinano ephezulu kakhulu ye-tungsten yethu yentsimbi enzima. I-W-Ni-Fe kunye ne-W-Ni-Cu yandisa kuphela encinci kakhulu kumaqondo aphezulu kwaye ichitha ubushushu ngokukodwa kakuhle. Njengokufakwa kokungunda kwisiseko se-aluminiyam, zinokufudunyezwa ngokuphindaphindiweyo kwaye zipholile ngaphandle kokuba zibe brittle.
Kwinkqubo ye-Electrical Discharge Machining (EDM), izinyithi zenziwe ngomatshini ukuya kwinqanaba elichanekileyo lokuchaneka ngokukhutshwa kombane phakathi kwendawo yokusebenza kunye ne-electrode. Xa i-electrode yobhedu kunye negraphite ingasebenzi, ii-electrode ze-tungsten-copper-ezikwaziyo ukunxiba ziyakwazi ukwenza umatshini kwanesinyithi esiqinileyo ngaphandle kobunzima. Kwimibhobho yokutshiza yeplasma kushishino lokugquma, iipropathi zezinto ze-tungsten kunye nobhedu kwakhona ziyancedisana ngokugqibeleleyo.
I-metallic tungsten yentsimbi enzima ibandakanya izinto ezimbini. Ngexesha lenkqubo yokuvelisa izigaba ezibini, isiseko se-porous sintered senziwa kuqala ukusuka kwicandelo kunye nenqanaba eliphezulu lokunyibilika, umzekelo isinyithi esichasayo, ngaphambi kokuba ii-pores ezivulekileyo zifakwe kunye necandelo elimanzi kunye nenqanaba eliphantsi lokunyibilika. Iipropati zecandelo ngalinye zihlala zingatshintshi. Xa kuhlolwa phantsi kwe-microscope, iipropati zecandelo ngalinye ziqhubeka zibonakala. Kwinqanaba le-macroscopic, nangona kunjalo, iipropathi zecandelo ngalinye zidityanisiwe. Njengemathiriyeli yentsimbi exutyiweyo, imathiriyeli entsha inokuthi, umzekelo, ibe ne-thermal conductivity entsha kunye namaxabiso okwanda kwe-thermal.
I-Liquid phase-sintered tungsten-heavy metals zenziwa ngomxube we-metal powders kwinkqubo yokuvelisa inqanaba elinye ngexesha apho amacandelo aneendawo ezisezantsi zokunyibilika anyibilikiswa kwezo zineendawo eziphezulu zokunyibilika. Ngethuba lesigaba se-binder, la macandelo enza i-alloys kunye nalawo anendawo ephezulu yokunyibilika. Nangona umlinganiselo omkhulu we-tungsten, enendawo ephezulu yokunyibilika, iyachithwa ngexesha lesigaba se-binder. Isigaba solwelo se-Plansee's sintered composite imathiriyeli ixhamla kuxinaniso lwecandelo le-tungsten, imodyuli yokunwebeka kunye nokukwazi ukufunxa i-X-reyi kunye ne-gamma radiation ngaphandle kokubandezeleka kuyo nayiphi na imiqobo eyayanyaniswa nokusetyenzwa kwe-tungsten ecocekileyo Ngokwahlukileyo, i-coefficient yokwandiswa kobushushu kunye thermal kunye conductivity zombane lwamacandelo ulwelo isigaba-sintered zixhomekeke kumlinganiselo omkhulu kakhulu kuqulunqo olubandakanyekayo kwisigaba sokubopha.
Izinto ezibuyisela umva ngaxeshanye zidibanisa izinto eziphathekayo zamacandelo amabini ahlukeneyo. Ngethuba le nkqubo, izinto ngokwazo zigcinwe kwimeko yazo yangaphambili kwaye ziboshwe kuphela kwi-junction encinci. Iintsimbi zidityaniswe kwi-mold ukwenza ibhondi yee-micrometers ezimbalwa ngobukhulu. Ngokungafaniyo nobuchule be-welding kunye ne-soldering, le ndlela izinzile ngokukodwa kwaye iqinisekisa ukuqhutyelwa kwe-thermal ephezulu.
