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 sePlansee's sintered composite materials benefit from the tungsten component's density, modulus of elasticity kunye nokukwazi ukufunxa i-X-reyi kunye ne-gamma radiation ngaphandle kokubandezeleka kuyo nayiphi na imiqobo eyayanyaniswa nokusetyenzwa kwe-tungsten esulungekileyo Ngokwahlukileyo, i-coefficient yokwandiswa kwe-thermal kunye ne-thermal kunye ne-conductivity yombane yesigaba solwelo-sintered ubukhulu bezinto ezibandakanyekayo kwisigaba solwelo-sintered kakhulu kwi-conductivity yesigaba solwelo.
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. Isinyithi sidityaniswe 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.
