Te tukanga whakaputa otungsten parahi koranu:
Ko te tukanga hangarau o te whakarite i te koranu tungsten-parahi ma te tikanga whakarewa paura ka whakamahia mo te whakaranu, te whakaiti, te hanga, te sintering, te whakarewa, te whakauru me te hanga makariri o nga kai paura.Tungsten-parahi, molybdenum-parahi ranei i konatunatua te paura ka pania ki te wahanga wai i te 1300-1500° i muri i te whakakao.Ko nga mea i mahia e tenei tikanga he kino te riterite, he maha nga waahi kati, a ko te tikanga he iti ake i te 98%.Ka taea te whakapai ake i te mahi sintering me te whakapai ake i te pai o te tungsten-copper me te molybdenum-copper alloys.Heoi, ko te whakakorikori nickel me te sintering ka tino whakaiti i te hiko me te waiariki o te rauemi, me te whakaurunga o nga poke i roto i te whakakotahi miihini ka whakaitihia te kawe o te rauemi;ko te tikanga whakaora tahi o te waikura ki te whakarite i nga paura he mahi hangarau uaua me te iti o te mana tukatuka, he uaua ki te mahi puranga.
1. Ko te tikanga whakakikorua i te werohanga he mea hanga te koranu tungsten teitei e te tikanga werohanga.Ko tana tikanga whakaputa ko te whakaranu i te paura nickel, te paura tungsten parahi, te paura rino ranei me te rahi o te matūriki o te 15 microns, te paura tungsten me te rahi o te matūriki o te 0.52 microns me te paura tungsten o te 515 microns, ka uru ki roto i te 25% 30% te binder organic. ( Pērā i te ware pi ma polymethacrylate ranei) werohia niao, horoi mamaoa me irradiation ki te tango i te here, me te sintering i roto i te reo ki te whiwhi teitei-kiato koranu tungsten.
2. Te tikanga o te paura o te konukura Te paura o te konukura (te whakaranu me te huri hei whakahoki i te parahi) hei utu mo te paura parahi, ka hanga te koranu parahi he matrix tonu i roto i te kiato sintered, ka whakamahia te tungsten hei anga whakapakari.Ko te waahanga pupuhi teitei e whakawhäitihia ana e te waahanga tuarua a tawhio noa, a, ka tukuna te paura ki te iti o te makuku mahana.Ko te whiriwhiringa o te paura tino pai ka taea te whakapai ake i te mahi sintering me te densification, ka nui ake i te 99%.
3. Ko te tikanga whakauru anga koiwi tungsten me te molybdenum i te tuatahi ka herea te paura tungsten, te paura molybdenum ranei ki te hanga, ka pania ki roto ki te anga tungsten me te molybdenum me tetahi porosity, katahi ka uru ki te parahi.He pai tenei tikanga mo nga hua parahi tungsten me te molybdenum me te iti o te ihirangi parahi.Ka whakatauritea ki te parahi tungsten, ko te parahi molybdenum te painga o te kounga iti, te hanga ngawari, te whakarea roha raina, te kawe waiariki me etahi taonga miihini nui me te parahi tungsten.Ahakoa ko te mahi aukati wera kaore i te pai ki tera o te parahi tungsten, he pai ake i etahi rauemi wera-wera, na reira he pai ake te whakamahi.Na te mea he kino ake te makuku o te molybdenum-parahi i tera o te tungsten-parahi, ina koa i te wa e whakarite ana te molybdenum-parahi me te iti o te konupora konupora, he iti te kiato pai o te rauemi i muri i te whakaurunga, ka hua mai te hau o te rauemi, te kawe hiko, me e kore e taea e te kawe waiariki te whakatutuki i nga whakaritenga.Ko tana whakamahinga he aukati.
