Okwu gbasara Tungsten Carbide

Site na mmepe nke teknụzụ, ndị mmadụ na-achụ ngwá ọrụ ka mma, na ihe maka ihe owuwu na azụmahịa ha. N'okpuru ikuku a, tungsten carbide na-arụ ọrụ dị mkpa na ụlọ ọrụ ọgbara ọhụrụ. Na n'isiokwu a, a ga-ewebata ụfọdụ okwu gbasara tungsten carbide.

1. carbide ciment

Carbide cimented na-ezo aka n'ihe mgbagwoju anya nke mejupụtara carbides metal refractory na ihe nkedo ọla mejupụtara. N'ime carbides ígwè, tungsten carbide, titanium carbide, tantalum carbide, na ndị ọzọ bụ carbide ndị a na-ejikarị eme ihe ugbu a. Na ihe nkedo igwe a na-ejikarị eme ihe bụ ntụ ntụ cobalt, a ga-ejikwa ihe ndị ọzọ na-ekekọta ígwè dị ka nickel, na ígwè, mgbe ụfọdụ.

2. Tungsten carbide

Tungsten carbide bụ ụdị carbide cimented, nke mejupụtara tungsten carbide ntụ ntụ na ihe nkedo ígwè. Site na ebe mgbaze dị elu, ngwaahịa tungsten carbide enweghị ike imepụta dị ka ihe ndị ọzọ. Ngwongwo ntụ ntụ bụ usoro a na-ahụkarị maka imepụta ngwaahịa carbide tungsten. Site na atom tungsten na carbon carbon, ngwaahịa tungsten carbide nwere ọtụtụ ihe dị egwu, na-eme ka ha bụrụ ihe eji ewu ewu na ụlọ ọrụ ọgbara ọhụrụ.

3. Njupụta

Njupụta na-ezo aka na oke nke oke na olu nke ihe. Olu ya nwekwara oke nke pores na ihe.

N'ime ngwaahịa carbide tungsten, cobalt ma ọ bụ ihe ndị ọzọ dị n'ígwè dị. Ọkwa tungsten carbide nkịtị YG8, nke nwere 8% cobalt, nwere njupụta nke 14.8g/cm3. Ya mere, ka ọdịnaya cobalt dị na tungsten-cobalt alloy na-abawanye, njupụta n'ozuzu ga-ebelata.

4. Isi ike

Isi ike na-ezo aka n'ikike nke ihe nwere ike iguzogide nrụrụ rọba. A na-ejikarị hardness Vickers na Rockwell hardness iji tụọ ike nke ngwaahịa carbide tungsten.

A na-eji ike ike Vickers eme ihe n'ụwa niile. Usoro nledo ike a na-ezo aka na uru siri ike enwetara site n'ịtụ nha nbanye site na iji diamond banye n'elu ihe nlele n'okpuru ụfọdụ ọnọdụ ibu.

Rockwell hardness bụ ụzọ ọzọ a na-eji tụọ ike ike nke a na-ejikarị. Ọ na-atụ ike ike site na iji omimi ntinye nke cone diamond ọkọlọtọ.

Enwere ike iji usoro nha ike siri ike nke Vickers na ụzọ Rockwell hardness maka tụọ ike nke carbide cemented, enwere ike ịtụgharị ha abụọ.

Ike nke tungsten carbide sitere na 85 HRA ruo 90 HRA. Ọkwa nkịtị nke tungsten carbide, YG8, nwere ike nke 89.5 HRA. Ngwaahịa tungsten carbide nwere ike siri ike nwere ike ịtachi obi ma na-eyi ya nke ọma, ya mere ọ nwere ike ịrụ ọrụ ogologo oge. Dị ka ihe jikọrọ ọnụ, obere cobalt na-akpata isi ike ka mma. Na obere carbon nwere ike ime ka tungsten carbide sie ike. Ma decarbonization nwere ike ime ka tungsten carbide dị mfe imebi. N'ozuzu, ezigbo tungsten carbide ga-abawanye ike ya.

5. Na-ehulata ike

A na-amụba ihe nlele ahụ dị ka ọkụ na-akwado nanị na fulcrums abụọ, a na-etinyekwa ibu n'ahịrị etiti nke fulcrums abụọ ahụ ruo mgbe ihe nlele ahụ kwụsịrị. A na-eji uru a na-agbakọ site na usoro winding dị ka ibu achọrọ maka mgbaji na mpaghara obe nke ihe atụ. Amarakwa dị ka ike mgbawa nke transverse ma ọ bụ nkwụchi.

Na WC-Co tungsten carbide, ike na-agbanwe agbanwe na-abawanye site na mmụba nke ọdịnaya cobalt nke tungsten-cobalt alloy, mana mgbe ọdịnaya cobalt ruru ihe dịka 15%, ike mgbanwe na-erute uru kachasị elu, wee malite ịgbadata.

A na-atụ ike mgbada site na nkezi nke ọtụtụ ụkpụrụ atụnyere. Uru a ga-agbanwekwa dị ka geometry nke ihe atụ, ọnọdụ elu, nrụgide dị n'ime, na ntụpọ dị n'ime nke mgbanwe ihe. Ya mere, ike na-agbanwe agbanwe bụ naanị ihe atụ nke ike, a pụghịkwa iji uru ike na-agbanwe agbanwedị ka ihe ndabere maka nhọrọ ihe.

6. ike mgbawa transverse

Ike mgbawa ntụgharị bụ ike nke tungsten carbide iguzogide ekwe. Tungsten carbide nwere ike mgbawa transverse ka mma na-esiri ike imebi n'okpuru mmetụta. Ọmarịcha tungsten carbide nwere ike mgbawa transverse ka mma. Na mgbe akụkụ nke tungsten carbide na-ekesa nke ọma, transverse dị mma, na tungsten carbide adịghị mfe imebi. Ike mgbawa nke ngwaahịa YG8 tungsten carbide dị gburugburu 2200 MPa.

7. Ike mmanye

Ike mmanye bụ ike ndọta fọdụrụnụ a tụrụ site na iji magnetize ihe ndọta n'ime carbide simented ruo na steeti juputara wee mebie ya.

Enwere mmekọrịta kpọmkwem n'etiti nkezi urughuru nha nke cemented carbide frasi na mmanye ike. Nke kacha mma nkezi urughuru nha nke magnetized adọ, na elu mmanye ike uru. N'ime ụlọ nyocha, a na-anwale ike mmanye site na onye na-anwale ike mmanye.

Ndị a bụ okwu nke tungsten carbide na njirimara ya. A ga-ewebatakwa okwu okwu ndị ọzọ n'isiokwu ndị na-esonụ.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi ndị ọzọ na nkọwa, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu ozi US na ala nke ibe.
