Usoro mmepụta nke tungsten carbide

Tungsten carbidebụ ihe mejupụtara tungsten na carbon.Isi ike ya yiri diamond.Njirimara kemịkalụ ya kwụsiri ike na ọ na-ewu ewu na mpaghara ụlọ ọrụ dị iche iche.Taa, Sidi Xiaobian ga-agwa gị banyere usoro mmepụta nke tungsten carbide.

Dị ka chọrọ nketungsten carbide rolasize, dị iche iche nha nke tungsten carbide na-eji dị iche iche nzube.Ngwa ihe eji egbutu Carbide, dị ka akụrụngwa ịkpụ agụba V, ezigbo alloy nwere ultrafine subfine tungsten carbide particles.Alloy siri ike na-eji ọkara urughuru tungsten carbide;A na-eme alloy maka ịkpụ ike ndọda na ịcha arọ bụ nke tungsten carbide na-adịchaghị njọ.Nkume a na-eji eme ihe na-egwupụta akụ nwere nnukwu ike na mmetụta dị ukwuu ma na-eji tungsten carbide na-enweghị isi.Obere mmetụta nkume, obere mmetụta ibu, na ọkara urughuru tungsten carbide dị ka akụrụngwa eyi na-eguzogide akụkụ;Na-emesi ike iyi nguzogide, nguzogide nrụgide na ịdị nro elu, a na-eji ultrafine ultrafine ọkara tungsten carbide dị ka akụrụngwa.Ngwá ọrụ mmetụta ahụ na-eji ngwa ngwa tungsten carbide ọkara na nke siri ike.

Tungsten carbide nwere usoro carbon ọdịnaya nke 6.128% (50% atomic).Mgbe ọdịnaya carbon nke tungsten carbide dị ukwuu karịa ọdịnaya carbon, carbon efu na-apụta na tungsten carbide.Ọnụnọ nke carbon efu na-eme ka ihe ndị gbara ya gburugburu tungsten carbide na-eto eto n'oge sintering, na-eme ka ụmụ irighiri carbide simenti na-enweghị isi.Tungsten carbide na-achọkarị carbon dị elu (≥6.07%) na carbon free (≤0.05%), ebe ngụkọta carbon dabere na usoro mmepụta na ngwa ngwa nke carbide cimented.

N'okpuru ọnọdụ nkịtị, ngụkọta carbon nke vacuum sintering tungsten carbide site paraffin na-ekpebi nke ọma site na mkpokọta oxygen ọdịnaya nke briquette tupu agbasa.Akụkụ nke ikuku oxygen mụbara site na 0.75 akụkụ, ya bụ, ngụkọta carbon nke tungsten carbide = 6.13%+ oxygen ọdịnaya% × 0.75 (na-eche na e nwere ikuku na-anọpụ iche na sintering ọkụ, n'ezie, ngụkọta carbon nke tungsten carbide na. Ọtụtụ n'ime ọkụ na-ekpo ọkụ na-erughị ọnụ ahịa a gbakọrọ) [4] Enwere ike kewaa mkpokọta carbon nke tungsten carbide nke China ka ọ bụrụ usoro paraffin atọ.

Vacuum sintered tungsten carbide nwere ngụkọta carbon ọdịnaya nke ihe dịka 6.18± 0.03% (carbon efu ga-abawanye).Ngụkọta carbon nke paraffin wax hydrogen sintering tungsten carbide bụ 6.13±0.03%.Ngụkọta carbon carbon nke roba hydrogen sintering tungsten carbide bụ 5.90±0.03%.Usoro ndị a na-agbanwe mgbe ụfọdụ.Ya mere, a na-ekpebi mkpokọta carbon nke tungsten carbide dabere na ọnọdụ akọwapụtara.
