Kuwanda kwakanyanya, kugona kuumbwa zvakanaka uye kushanda zvakanaka, kuramba ngura zvakanyanya, kusimba kwakanyanya, kufambisa kupisa kunoshamisa uye kuwedzera kupisa kwakaderera. Tinopa: tungsten heavy metal alloys yedu.
"Zvinhu zvedu zvinorema" zvinoshandiswa, semuenzaniso, mumaindasitiri endege nendege, tekinoroji yekurapa, maindasitiri emotokari nekugadzira simbi kana pakuchera mafuta negasi. Tinoratidza zvitatu zvacho pazasi:
Zvishandiso zvedu zve tungsten heavy metal W-Ni-Fe neW-Ni-Cu zvine density yakanyanya (17.0 kusvika 18.8 g/cm3) uye zvinodzivirira kubva kuX-ray ne gamma radiation. Zvese W-Ni-Fe nezvinhu zvedu zvisina magnetic W-Ni-Cu zvinoshandiswa kudzivirira semuenzaniso mukushandiswa kwekurapa asiwo muindasitiri yemafuta negesi. Sema collimators mumidziyo ye radiation therapy, zvinovimbisa kuti zvinoonekwa zvakanaka. Pakuenzanisa huremu tinoshandisa density yakanyanya ye tungsten heavy metal alloy yedu. W-Ni-Fe neW-Ni-Cu zvinokura zvishoma chete pakupisa kwakanyanya uye zvinobvisa kupisa zvakanyanya. Sezvishandiso zve mold zve aluminium foundry, zvinogona kupiswa kakawanda uye kutonhodzwa pasina kupwanyika.
Mukushanda kweMagetsi Ekubudisa Mashini (EDM), simbi dzinogadzirwa nemachina akanyatsogadzirwa nemagetsi pakati pechinhu chebasa neelectrode. Kana maelectrode emhangura negrafiti asina kunyatsogadzirwa, maelectrode emhangura netungsten asingaparare anokwanisa kugadzira simbi dzakaoma pasina dambudziko. Muma nozzles eplasma eindasitiri yekuputira, hunhu hwetungsten nemhangura hunoenderana zvakare zvakakwana.
Simbi dzinorema dzesimbi dzakapinzwa mu tungsten dzine zvikamu zviviri. Munguva yekugadzira ine zvikamu zviviri, hwaro hune porous sintered hunotanga hwagadzirwa kubva muchikamu chine poindi yepamusoro yekunyunguduka, semuenzaniso simbi isingagadzike, maburi akavhurika asati apinzwa nechikamu chakanyunguduka chine poindi yakaderera yekunyunguduka. Hunhu hwezvikamu zvega zvega hunoramba hwakachinja. Kana hukaongororwa uchishandisa maikorosikopu, hunhu hwechikamu chimwe nechimwe hunoramba huchionekwa. Zvisinei, padanho remacroscopic, hunhu hwezvikamu zvega zvega hunosanganiswa. Sezvinhu zvesimbi zvakasanganiswa, chinhu chitsva chinogona, semuenzaniso, kuva nekupisa kutsva uye kuwedzera kwekupisa.
Metals dzinonzi liquid phase-sintered tungsten-heavy metals dzinogadzirwa kubva mumusanganiswa weupfu hwesimbi muchikamu chimwe chete chekugadzira umo zvikamu zvine nzvimbo dzakaderera dzekunyunguduka zvinonyungudutswa kune izvo zvine nzvimbo dzakanyanya kunyunguduka. Munguva yechikamu chebinder, zvikamu izvi zvinoumba alloys neizvo zvine nzvimbo yakakwidza yekunyunguduka. Kunyangwe huwandu hwakawanda hwetungsten, ine nzvimbo yakakwidza yekunyunguduka, hunonyungudutswa panguva yechikamu chebinder. Zvinhu zvePlansee's liquid phase sintered composite zvinobatsirwa nehukuru hwechikamu chetungsten, modulus ye elasticity uye kugona kupinza X-ray ne gamma radiation pasina kutambura nechero chipi zvacho chezvikanganiso zvine chekuita nekugadzirwa kwe pure tungsten. Kusiyana neizvi, coefficient yekuwedzera kwekupisa uye thermal ne electrical conductivity yezvikamu zve liquid phase-sintered zvinoenderana zvakanyanya nekugadzirwa kunobatanidzwa muchikamu chebinder.
Zvinhu zvakagadzirwa ne back-cast zvinosanganisa zvinhu zviviri zvakasiyana panguva imwe chete. Munguva iyi, zvinhu zvacho zvinoramba zviri mumamiriro azvo ekutanga uye zvinongobatanidzwa chete pakona diki. Simbi dzinobatanidzwa muforoma kuti dzigadzire chisungo chema micrometer mashoma chete. Kusiyana nehunyanzvi hwekuwelda nesoldering, nzira iyi yakasimba uye inoita kuti kupisa kupfuure zvakanaka.
