Uxinano oluphezulu, ukwakheka okugqwesileyo kunye nokusebenza kakuhle, ukumelana nokugqwala okugqwesileyo, imodulus ephezulu yokuthamba, ukuqhuba kobushushu okumangalisayo kunye nokwanda okuphantsi kobushushu. Sibonisa: ii-alloys zethu ze-tungsten heavy metal.
"Iintsimbi zethu ezisindayo" zisetyenziswa, umzekelo, kumashishini eenqwelo moya kunye neendiza, iteknoloji yezonyango, amashishini eemoto kunye neemveliso zezixhobo okanye ekugrumbeni ioyile negesi. Siza kubonisa kafutshane ezintathu kwezi zilandelayo:
Iialloy zethu ze-tungsten heavy metal W-Ni-Fe kunye ne-W-Ni-Cu zinoxinano olukhulu kakhulu (17.0 ukuya kwi-18.8 g/cm3) kwaye zibonelela ngokhuselo oluthembekileyo kwi-X-ray kunye ne-gamma radiation. Zombini i-W-Ni-Fe kunye nezinto zethu ezingezizo zemagnethi i-W-Ni-Cu zisetyenziselwa ukhuselo umzekelo kwizicelo zonyango kodwa nakwishishini leoyile negesi. Njengee-collimators kwizixhobo zonyango lwemitha ziqinisekisa ukuvezwa ngokuchanekileyo. Ekulinganiseni ubunzima sisebenzisa uxinano olukhulu kakhulu lwe-tungsten heavy metal alloy yethu. I-W-Ni-Fe kunye ne-W-Ni-Cu zanda kancinci kakhulu kumaqondo obushushu aphezulu kwaye zisusa ubushushu kakuhle. Njengezinto zokubumba zomsebenzi we-aluminium foundry, zinokufudunyezwa ngokuphindaphindiweyo kwaye zipholiswe ngaphandle kokuba ziqhekeke.
Kwinkqubo ye-Electrical Discharge Machining (EDM), iintsimbi zenziwa ngomatshini ngokuchanekileyo kakhulu ngokusebenzisa umbane ophumayo phakathi kwesixhobo somsebenzi kunye ne-electrode. Xa ii-electrode ze-copper kunye ne-graphite zingakulungelanga ukusebenza, ii-electrode ze-tungsten-copper ezingagugiyo ziyakwazi umatshini nokuba ziintsimbi eziqinileyo ngaphandle kobunzima. Kwii-nozzles ze-plasma spray kushishino lokugquma, iipropati zezinto ze-tungsten kunye ne-copper ziphinda zihambelane ngokugqibeleleyo.
Iimetali ezinzima ze-tungsten zesinyithi ezifakwe ngaphakathi ziqulathe izinto ezimbini. Ngexesha lenkqubo yokuvelisa enamanqanaba amabini, isiseko esineembobo siqala siveliswe kwinxalenye enendawo yokunyibilika ephezulu, umzekelo isinyithi esirhabaxa, ngaphambi kokuba iimbobo ezivulekileyo zifakwe kwinxalenye enyibilikayo enenqanaba lokunyibilika eliphantsi. Iimpawu zenxalenye nganye azitshintshi. Xa zihlolwa phantsi kwe-microscope, iimpawu zenxalenye nganye ziyaqhubeka nokubonakala. Nangona kunjalo, kwinqanaba le-macroscopic, iimpawu zenxalenye nganye ziyadityaniswa. Njengezinto zentsimbi ezihlanganisiweyo, izinto ezintsha, umzekelo, zinokuba nexabiso elitsha lokuqhuba ubushushu kunye namaxabiso okwandisa ubushushu.
Iimetali eziqinileyo ze-tungsten ezifakwe kwisigaba solwelo zenziwe ngomxube weempuphu zesinyithi kwinkqubo yokuvelisa yesigaba esinye apho izinto ezinamaqondo okunyibilika aphantsi zinyibilikiswa kwezo zinamanqaku okunyibilika aphezulu. Ngexesha lesigaba sokubopha, ezi zinto zenza ii-alloys kunye nezo zineqondo lokunyibilika eliphezulu. Kwanesixa esikhulu se-tungsten, esineqondo lokunyibilika eliphezulu, siyanyibilika ngexesha lesigaba sokubopha. Izinto ezidityanisiweyo zesigaba solwelo ze-Plansee zixhamla kubuninzi be-tungsten component, i-modulus yokuguquguquka kunye nokukwazi ukufunxa i-X-ray kunye ne-gamma radiation ngaphandle kokubandezeleka kuzo naziphi na iingxaki ezinxulumene nokucutshungulwa kwe-tungsten ecocekileyo. Ngokwahlukileyo koko, i-coefficient yokwandiswa kobushushu kunye ne-thermal kunye ne-electric conductivity ye-liquid phase-sintered components ixhomekeke kakhulu kulwakhiwo olubandakanyekayo kwisigaba sokubopha.
Izinto ezifakwe ngasemva ngaxeshanye zidibanisa iimpawu zezinto ezibonakalayo zezinto ezimbini ezahlukeneyo. Ngexesha lale nkqubo, izinto ngokwazo zigcinwa zikwimeko yazo yokuqala kwaye zibotshelelwa kuphela kwindawo encinci yokuhlangana. Iintsimbi zidityaniswe kwisikhunta ukuze zenze ibhondi yee-micrometer ezimbalwa ngobukhulu. Ngokungafaniyo neendlela zokuwelda kunye nokunyibilikisa, le ndlela izinzile ngakumbi kwaye iqinisekisa ukuhanjiswa kobushushu okufanelekileyo.
