Usoro mmepụta nke tungsten ọla kọpa alloy

Usoro mmepụta nketungsten ọla kọpa alloy:
A na-eji usoro teknụzụ nke ịkwadebe tungsten-ọla kọpa alloy site na ntụ ntụ metallurgy usoro maka ịgwakọta, ịmachi, akpụ, sintering, agbaze, infiltration na oyi mmepụta nke ntụ ntụ.Tungsten-ọla kọpa ma ọ bụ molybdenum-ọla kọpa ntụ ntụ ntụ ntụ na-agbanye n'ime mmiri mmiri na 1300-1500 ° mgbe ịkpụzi mmachi.Ihe a kwadebere site na usoro a nwere otu adịghị mma, enwere ọtụtụ oghere mechiri emechi, na njupụta dị mma na-adịkarị ala karịa 98%.Ọ nwere ike melite ọrụ sintering ma melite ịdị mma nke tungsten-ọla kọpa na molybdenum-ọla kọpa alloys.Otú ọ dị, nickel activation na sintering ga-ebelata ọkụ eletrik na thermal conductivity nke ihe onwunwe, na iwebata adịghị ọcha na n'ibu alloy ga-ebelatakwa conductivity nke ihe;usoro mgbake oxide iji kwadebe ntụ ntụ nwere usoro teknụzụ dị egwu na ike nhazi dị ala, na-eme ka o sie ike ịme usoro nhazi.
1. Usoro ịkpụzi injection Tungsten alloy dị elu na-eme ya site na usoro ịkpụzi injection.Usoro mmepụta ya bụ ịgwakọta ntụ ntụ nickel, ọla kọpa tungsten ntụ ntụ ma ọ bụ ntụ ntụ ígwè nwere otu nha nha nke 15 microns, ntụ ntụ tungsten nwere oke nha nke 0.52 microns na tungsten ntụ ntụ nke 515 microns, wee gwakọta ya na 25% 30% organic binder (Dị ka ihe na-acha ọcha ma ọ bụ polymethacrylate, na-ehicha ihe na-ehicha ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ dị elu). njupụta tungsten alloy.
2. Ọla kọpa oxide ntụ ntụ usoro ọla kọpa oxide ntụ ntụ (ịgwakọta na egweri iji weghachi ọla kọpa) kama metal ọla kọpa ntụ ntụ, ọla kọpa alloy Nleta a na-aga n'ihu matrix na sintered kọmpat, na tungsten na-eji dị ka a ike kpuchie.Akụkụ nke ọzịza dị elu na-ejedebe site na mpaghara nke abụọ gbara ya gburugburu, yana ntụ ntụ na-agbanye na iru mmiri dị ala.Nhọrọ nke ezigbo ntụ ntụ nwere ike imeziwanye arụmọrụ sintering na densification, na-eme ka ọ karịa 99%.
3. Usoro mgbaba ọkpụkpụ tungsten na molybdenum na-ebu ụzọ mechie tungsten ntụ ntụ ma ọ bụ ntụ ntụ molybdenum ka ọ na-akpụzi, ma mee ka ọ bụrụ ọkpụkpụ tungsten na molybdenum nwere ụfọdụ porosity, wee banye na ọla kọpa.Usoro a dabara adaba maka ọla kọpa tungsten na ngwaahịa ọla kọpa molybdenum nwere obere ọla kọpa.E jiri ya tụnyere ọla kọpa tungsten, ọla kọpa molybdenum nwere uru nke obere mma, mmepụta dị mfe, ọnụọgụ mgbasawanye linear, conductivity thermal na ụfọdụ ihe eji arụ ọrụ na tungsten ọla kọpa.Ọ bụ ezie na ọrụ nkwụsị ọkụ adịghị mma dị ka nke tungsten ọla kọpa, ọ dị mma karịa ụfọdụ ihe ndị na-ekpo ọkụ na-ekpo ọkụ, ya mere ọ nwere atụmanya ka mma nke iji.N'ihi na wettability nke molybdenum-ọla kọpa dị njọ karịa nke tungsten-ọla kọpa, karịsịa mgbe a na-akwadebe molybdenum-ọla kọpa na ala ọla kọpa alloy ọdịnaya, mma njupụta nke ihe mgbe infiltration dị ala, na-akpata na ihe nke ikuku tightness, eletriki conductivity, na thermal conductivity enweghị ike izute ihe a chọrọ.Amachibidoro ojiji ya.
