Inqubo yokukhiqiza yei-tungsten yethusi ingxubevange:
Inqubo yezobuchwepheshe yokulungiselela i-tungsten-copper alloy by powder metallurgy method isetshenziselwa ukuxuba, ukukhawulela, ukwakha, ukucwilisa, ukuncibilika, ukungena kanye nokukhiqizwa okubandayo kwezithako eziyimpuphu.I-Tungsten-copper noma i-molybdenum-copper powder exutshwe ne-sintered esigabeni se-liquid ku-1300-1500 ° ngemva kokubunjwa kokuvalelwa.Izinto ezilungiswe ngale ndlela zinokufana okubi, kunezikhala eziningi ezivaliwe, futhi ukuminyana okuhle ngokuvamile kungaphansi kwama-98%.Ingathuthukisa umsebenzi we-sintering futhi ithuthukise ukucoleka kwama-alloys e-tungsten-copper kanye ne-molybdenum-copper.Kodwa-ke, ukusebenza kwe-nickel kanye ne-sintering kuzonciphisa kakhulu ukuqhutshwa kukagesi nokushisa kwempahla, futhi ukwethulwa kokungcola ku-alloying yemishini kuzophinde kunciphise ukuqhutshwa kwezinto;indlela yokubuyisela i-oxide yokulungisa izimpushana inenqubo yobuchwepheshe enzima namandla okucubungula aphansi, okwenza kube nzima ukuhlanganisa inqubo.
1. Indlela yokubumba yomjovo Ingxubevange ye-tungsten ephezulu-density yenziwa ngendlela yokubumba umjovo.Indlela yokukhiqiza yayo ukuxuba impushana ye-nickel, i-tungsten yethusi powder noma i-iron powder enosayizi wezinhlayiyana eziyi-15 microns, i-tungsten powder enosayizi wezinhlayiyana ezingama-microns angu-0.52 kanye ne-tungsten powder engama-microns angu-515, bese uxuba ngo-25% 30% i-organic binder ( Njenge-wax emhlophe noma i-polymethacrylate ukuze ukhiphe umjovo we-moderning, umshini wokuhlanza nokukhipha umjovo we-moderning, umshini wokuhlanza nokukhipha umjovo ophakathi ukuminyana tungsten ingxubevange.
2. Indlela ye-Copper oxide powder I-Copper oxide powder (ukuxuba nokugaya ukuze kubuyiselwe ithusi) esikhundleni se-powder yethusi yensimbi, i-alloy yethusi yakha i-matrix eqhubekayo ku-compact sintered, futhi i-tungsten isetshenziswa njengohlaka oluqinisayo.Ingxenye yokuvuvukala ephezulu inqunyelwe ingxenye yesibili ezungezile, futhi impushana ifakwe emanzini okushisa aphansi.Ukukhethwa kwe-powder enhle kakhulu kungathuthukisa ukusebenza kwe-sintering nokuqina, okwenza kube ngaphezu kwe-99%.
3. Indlela yokungenisa i-tungsten ne-molybdenum skeleton okokuqala ihlanganisa impushana ye-tungsten noma impushana ye-molybdenum ukuze ibumbe, futhi iyifake kuhlaka lwamathambo e-tungsten ne-molybdenum olunokuqina okuthile, bese lungena ngethusi.Le ndlela ifaneleka kumikhiqizo yethusi ye-tungsten ne-molybdenum enokuqukethwe kwethusi okuphansi.Uma kuqhathaniswa nethusi le-tungsten, ithusi le-molybdenum linezinzuzo zekhwalithi encane, ukukhiqizwa okulula, i-coefficient yokwandisa okuqondile, ukuqhutshwa kokushisa kanye nezinye izakhiwo ezinkulu zemishini kanye nethusi le-tungsten.Nakuba umsebenzi wokumelana nokushisa ungemuhle njengalowo wethusi we-tungsten, ungcono kunezinye izinto ezikwazi ukumelana nokushisa, ngakho unethuba elingcono lokusebenzisa.Ngenxa yokuthi ukumanzisa kwe-molybdenum-copper kubi kakhulu kunaleyo ye-tungsten-copper, ikakhulukazi lapho ulungiselela i-molybdenum-copper enokuqukethwe okuphansi kwe-alloy yethusi, ukuminyana okuhle kwezinto ngemuva kokungeniswa kuphansi, okuholela ekubambeni komoya wezinto ezibonakalayo, ukuqhutshwa kukagesi, kanye ne-thermal conductivity ayikwazi ukuhlangabezana nezidingo.Ukusetshenziswa kwayo kukhawulelwe.
