Ngwaahịa Carbide Sintered Cemented na nyocha ihe kpatara ya

Carbide cimented bụ ngwaahịa metallurgy ntụ ntụ nke etinyere n'ọkụ na-ekpo ọkụ ma ọ bụ ọkụ mbelata hydrogen nwere cobalt, nickel, na molybdenum dị ka akụkụ bụ isi nke tungsten carbide micron-sized ntụ ntụ nke metal siri ike refractory dị elu.Sintering bụ nzọụkwụ dị oke egwu na carbide cimented.Ihe a na-akpọ sintering bụ ikpokọta ntụ ntụ na-ekpo ọkụ na okpomọkụ, debe ya ruo oge ụfọdụ, wee mee ka ọ dị jụụ iji nweta ihe nwere ihe ndị a chọrọ.Usoro nhazi nke cemented carbide dị nnọọ mgbagwoju anya, ọ dịkwa mfe ịmepụta ihe mkpofu sintered ma ọ bụrụ na ị kpacharaghị anya.Taa, Chuangrui Xiaobian ga-eso gị kerịta ihe mkpofu nkịtị na ihe kpatara ya.

1. Carbide sintered mkpofu bụ nke mbụ na-akpụcha
Ya bụ, elu nke carbide cimented na-agafe na mgbawa n'akụkụ ya, na-agbaji shells ma ọ bụ mgbawa, na n'ọnọdụ ndị siri ike, obere akpụkpọ anụ dị ka akpịrịkpa azụ, gbawara agbawa, na ọbụna nhịahụ.Akpụkpọ ahụ na-abụkarị n'ihi mmetụta kọntaktị nke cobalt na kọmpat, nke mere na carbon nwere gas na-emebi carbon n'efu n'ime ya, na-ebute mbelata ike mpaghara nke kọmpat, na-ebute peeling.

2. Nke abụọ na-emekarị cimented carbide sintered mkpofu bụ oghere
A na-akpọ pores n'elu 40 microns.Ihe ndị nwere ike ime ka ọnya nwere ike ịmalite pores.Tụkwasị na nke ahụ, mgbe enwere ihe ndị na-adịghị ọcha n'ime ahụ nke na-adịghị edozi site na ígwè a wụrụ awụ, dị ka nnukwu pores dị ka "adịghị agwụ agwụ", ma ọ bụ anụ ahụ na-eme ka ọ dị njọ nwere akụkụ siri ike na nkewa nke mmiri mmiri nwere ike ịmepụta pores.

3. Ihe mkpofu nke simenti carbide sintered nke atọ a na-ahụkarị bụ ọnya
Enwere oghere na ngwaahịa carbide alloy cimented, na convex curved elu na-apụta n'elu akụkụ ndị kwekọrọ.A na-akpọ ihe omume a ọnya.Isi ihe kpatara ọnya ọnya bụ n'ihi na ahụ e mechiri emechi nwere nnukwu gas.A na-enwekarị ụdị abụọ: otu bụ na ikuku na-agbakọba n'ime ahụ nke e mebiri emebi, na n'oge a na-eme mkpọtụ, ikuku na-esi n'ime ime gaa n'elu.Ọ bụrụ na enwere adịghị ọcha nke ụfọdụ nha n'ime ahụ e megharịrị, dị ka scrap alloy, scrap iron, na cobalt scrap, ikuku ga-elekwasị anya ebe a.Mgbe aru ahụ mebiri emebi pụtara n'oge mmiri mmiri wee mebie ya, enweghị ike ịpụpụ ikuku.Ọnya na-etolite n'elu kacha nta.

Nke abụọ bụ na e nwere mmeghachi omume kemịkalụ nke na-emepụta nnukwu gas n'ime ahụ e tere mmanụ.Mgbe e nwere ụfọdụ oxides n'ime ahụ siri ike, ha na-ebelata mgbe usoro mmiri mmiri na-egosi na ọ na-emepụta gas, nke ga-eme ka ngwaahịa afụ;WC-CO alloys na-abụkarị nke ihe kpatara agglomeration nke oxides na ngwakọta.

5, ma mgbe ahụ enwere nrụrụ
A na-akpọ ngbanwe ọdịdị na-adịghị ahụkebe nke ahụ mebiri emebi.Isi ihe kpatara nrụrụ ahụ bụ ndị a: nkesa njupụta nke compacts abụghị otu, n'ihi na njupụta nke alloy emechara bụ otu;ahụ siri ike enweghị carbon na mpaghara, n'ihi na enweghị carbon na-ebelata usoro mmiri mmiri dịtụ;Ịkwado ụgbọ mmiri enweghị ezi uche;efere a na-akwado ya adịghị ekwekọ.
