Mokhoa oa tlhahiso eamotsoako oa koporo oa tungsten:
Mokhoa oa tekheniki oa ho lokisa motsoako oa tungsten-copper alloy ka mokhoa oa metallurgy oa phofo o sebelisoa bakeng sa ho kopanya, ho fokotsa, ho etsa, ho sintering, ho qhibiliha, ho kenella le ho hlahisa lihlahisoa tse batang tsa phofo.Tungsten-koporo kapa molybdenum-koporo phofo e tsoakiloeng e tšeloa ka har'a mokelikeli ho 1300-1500 ° ka mor'a ho bōptjoa ha litlamong.Lintho tse lokiselitsoeng ka mokhoa ona li na le ho se tšoane hantle, ho na le libaka tse ngata tse koetsoeng, 'me boima bo botle hangata bo tlase ho 98%.E ka ntlafatsa ts'ebetso ea sintering le ho ntlafatsa botle ba li-alloys tsa koporo tsa tungsten-koporo le molybdenum-copper.Leha ho le joalo, ts'ebetso ea nickel le sintering e tla fokotsa haholo mokhoa oa motlakase le oa mocheso oa thepa, 'me ho kenngoa ha litšila ka motsoako oa mechine ho tla boela ho fokotse conductivity ea thepa;mokhoa oa oxide co-recovery ho lokisa phofo o na le ts'ebetso e boima ea tekheniki le matla a tlase a ho sebetsa, ho etsa hore ho be thata ho etsa li-batch.
1. Mokhoa oa ho bopa ka ente Alloy ea tungsten e phahameng-density e entsoe ka mokhoa oa ho bopa ente.Mokhoa oa eona oa tlhahiso ke ho kopanya phofo ea nickel, phofo ea tungsten ea koporo kapa phofo ea tšepe e nang le boholo bo lekanang ba li-micron tse 15, phofo ea tungsten e nang le karoloana ea 0.52 microns le tungsten phofo ea 515 microns, ebe o kopanya ka 25% 30% organic binder (joalo ka boka ba boka bo bosoeu kapa polymethacrylate ho tlosa mouoane o phahameng, ho hloekisa le ho tlosa mouoane ka har'a mouoane. tšubuhlellano ea tungsten motsoako.
2. Copper oxide powder mokhoa oa Copper oxide phofo (ho kopanya le ho sila ho tsosolosa koporo) ho e-na le phofo ea koporo ea tšepe, motsoako oa koporo o etsa matrix a tsoelang pele ka har'a sintered compact, 'me tungsten e sebelisoa e le moralo o matlafatsang.Karolo e phahameng ea ho ruruha e lekanyelitsoe ke karolo ea bobeli e potolohileng, 'me phofo e silafatsoa ka mongobo o tlase oa mocheso.Khetho ea phofo e ntle haholo e ka ntlafatsa ts'ebetso ea sintering le densification, e etsa hore e be ho feta 99%.
3. Mokhoa oa ho kenella ha masapo a tungsten le molybdenum skeleton pele o kopanya phofo ea tungsten kapa phofo ea molybdenum hore e be sebopeho, ebe o e tšela ka har'a skeleton ea tungsten le molybdenum e nang le porosity e itseng, ebe e kenella ka koporo.Mokhoa ona o loketse lihlahisoa tsa koporo tsa tungsten le molybdenum tse nang le koporo e tlaase.Ha e bapisoa le koporo ea tungsten, koporo ea molybdenum e na le melemo ea boleng bo fokolang, tlhahiso e bonolo, coefficient ea ho atolosa linear, conductivity ea mocheso le lisebelisoa tse ling tse kholo tsa mochine le koporo ea tungsten.Le hoja mosebetsi oa ho hanyetsa mocheso o sa tšoane le oa koporo ea tungsten, o molemo ho feta lisebelisoa tse ling tse thibelang mocheso, kahoo o na le tebello e ntle ea tšebeliso.Hobane mongobo oa molybdenum-koporo o mpe ho feta oa tungsten-koporo, haholo-holo ha o lokisetsa molybdenum-koporo e nang le likarolo tse tlaase tsa koporo ea koporo, boleng bo botle ba thepa ka mor'a ho kenella bo tlaase, e leng se etsang hore moea oa thepa e be thata, conductivity ea motlakase le conductivity ea mocheso e ke keng ea finyella litlhoko.Tšebeliso ea eona e thibetsoe.
