Inkqubo yemveliso yeingxubevange yobhedu tungsten:
Inkqubo yobuchwephesha yokulungiselela i-tungsten-copper alloy nge-powder metallurgy method isetyenziselwa ukuxuba, ukukhawulela, ukwenza, ukuxubha, ukunyibilika, ukungena kunye nokuveliswa okubandayo kwezithako ezinomgubo.I-Tungsten-copper okanye i-molybdenum-copper powder exutywe nge-sintered kwinqanaba le-liquid kwi-1300-1500 ° emva kokubunjwa kokuvalelwa.Izinto ezilungiselelwe yile ndlela zinokufana okungahambi kakuhle, kukho iindawo ezininzi ezivaliweyo, kwaye ukuxinana okucokisekileyo ngokuqhelekileyo kungaphantsi kwama-98%.Iyakwazi ukuphucula umsebenzi we-sintering kwaye iphucule i-fineness ye-tungsten-copper kunye ne-molybdenum-copper alloys.Nangona kunjalo, ukusetyenziswa kwe-nickel kunye ne-sintering kuya kunciphisa kakhulu umbane kunye ne-thermal conductivity yezinto eziphathekayo, kwaye ukuqaliswa kokungcola kwi-alloying mechanical kuya kunciphisa ukuhanjiswa kwezinto;indlela yokubuyisela i-oxide yokulungisa i-powders inenkqubo enzima yobugcisa kunye negunya eliphantsi lokucwangcisa, okwenza kube nzima inkqubo yebhetshi.
1. Indlela yokubumba i-injection ye-high-density tungsten alloy yenziwe nge-injection yokubumba indlela.Indlela yayo yokuvelisa kukuxuba umgubo wenickel, umgubo wetungsten yobhedu okanye umgubo wentsimbi kunye nobungakanani besuntswana elifanayo le-microns eziyi-15, umgubo we-tungsten kunye nobungakanani besuntswana le-0.52 microns kunye nomgubo we-tungsten we-515 microns, kwaye emva koko uxube kwi-25% 30% ye-organic binder (Efana newax emhlophe okanye i-polymethacrylate yokususa, ukucoca umphunga kunye nokucoca i-irralding ephakathi, ukukhupha i-irralding ephakathi kunye ne-irralding ephakathi, ukucoca kunye ne-irralding ephakathi, ukucoca kunye ne-irralding i-modium, i-irralding ephakathi kunye nokucoca i-irralding ephakathi Ubuninzi be-tungsten ingxubevange.
2. I-Copper oxide powder indlela ye-Copper oxide powder (ukuxuba kunye nokugaya ukubuyisela ubhedu) endaweni yensimbi yobhedu, i-alloy yobhedu yenza i-matrix eqhubekayo kwi-compact sintered, kwaye i-tungsten isetyenziswe njengesakhelo esomeleza.Icandelo eliphezulu lokudumba lilinganiselwe licandelo lesibini elijikelezileyo, kwaye i-powder ifakwe kwi-sintered kwiqondo lokushisa eliphantsi.Ukukhethwa komgubo ocolekileyo kunokuphucula ukusebenza kwe-sintering kunye noxinaniso, okwenza kube ngaphezu kwe-99%.
3. Indlela yokungena kwe-tungsten kunye ne-molybdenum skeleton kuqala idibanisa umgubo we-tungsten okanye umgubo we-molybdenum ukuze umise, kwaye udibanise kwi-tungsten kunye ne-molybdenum skeleton kunye ne-porosity ethile, kwaye emva koko ingene ngobhedu.Le ndlela ifanelekile kwimveliso yobhedu ye-tungsten kunye ne-molybdenum kunye nomxholo wobhedu ophantsi.Xa kuthelekiswa nobhedu lwe-tungsten, i-molybdenum yethusi ineenzuzo zomgangatho omncinci, imveliso elula, i-coefficient yokwandisa i-linear, i-thermal conductivity kunye nezinye iipropati ezinkulu zomatshini kunye ne-tungsten yobhedu.Nangona umsebenzi wokumelana nobushushu ungekho mhle njengalowo wobhedu we-tungsten, ungcono kunezinye izinto ezikwazi ukumelana nobushushu, ngoko ke unethemba elingcono lokusetyenziswa.Ngenxa yokuba ukumanzi kwe-molybdenum-copper kubi kakhulu kune-tungsten-copper, ngakumbi xa ulungiselela i-molybdenum-copper kunye nomxholo we-alloy copper ephantsi, ubuninzi bezinto eziphathekayo emva kokungena ngaphakathi buphantsi, okubangelwa ukuxinwa komoya wezinto eziphathekayo, ukuqhutyelwa kombane, kunye ne-thermal conductivity ayikwazi ukuhlangabezana neemfuno.Ukusetyenziswa kwayo kuthintelwe.
