Njupụta nke Tungsten Carbide

Tungsten Carbide, nke a maara dị ka ezé ụlọ ọrụ mmepụta ihe, bụ ngwaahịa a na-ahụkarị. A ma ama maka ihe ndị magburu onwe ya gụnyere ike siri ike, ike dị elu, njupụta dị elu, na-eguzogide ọgwụ, na mgbochi corrosion, nke mere na, enwere ike ịme ya ka ọ bụrụ ihe ọkụkụ dị iche iche, ndị na-egbu osisi, ngwá ọrụ ịkụ nkume, ngwá ọrụ Ngwuputa, akụkụ eyi, cylinder liners. , were gabazie. Na ụlọ ọrụ ahụ, anyị ga-etinye ọtụtụ paramita iji nwalee ma hụ na ngwaahịa tungsten carbide dị oke mma. N'isiokwu a, a ga-ekwu maka njirimara anụ ahụ bụ isi, njupụta.

Gịnị bụ njupụta?

Njupụta bụ ihe dị mkpa n'ibu index index iji gosi uka nke simenti carbide kwa otu olu. Olu anyị kwuru ebe a, gụnyere olu nke pores na ihe. Dị ka usoro mba ụwa na nkeji nha iwu nke China si dị, njupụta na-anọchi anya akara ρ, na unit nke njupụta bụ kg / m3.

Njupụta nke tungsten carbide

N'okpuru otu usoro mmepụta ihe na otu paramita ahụ, njupụta nke carbide cemented ga-agbanwe site na mgbanwe nke ihe mejupụtara kemịkalụ ma ọ bụ ngbanwe nke oke akụrụngwa.

Akụkụ bụ isi nke usoro YG cemented carbide bụ tungsten carbide ntụ ntụ na ntụ ntụ cobalt. N'okpuru ọnọdụ ụfọdụ, ka ọdịnaya cobalt na-abawanye, njupụta alloy na-ebelata, ma mgbe uru dị oke egwu ruru, oke ngbanwe njupụta dị ntakịrị. Njupụta nke alloy YG6 bụ 14.5-14.9g/cm3, njupụta nke alloy YG15 bụ 13.9-14.2g/cm3, na njupụta nke alloy YG20 bụ 13.4-13.7g/cm3.

Isi ihe dị na YT usoro cemented carbide bụ tungsten carbide ntụ ntụ, titanium carbide ntụ ntụ na cobalt ntụ ntụ. N'okpuru ọnọdụ ụfọdụ, ka ọdịnaya nke titanium carbide ntụ ntụ na-abawanye, njupụta nke alloy na-ebelata. Njupụta alloy YT5 12.5-13.2g/cm3, YT14 alloy density 11.2-12.0g/cm3, YT15 alloy density 11.0-11.7g/cm3

Isi ihe dị na YW usoro cemented carbide bụ tungsten carbide ntụ ntụ, titanium carbide ntụ ntụ, tantalum carbide ntụ ntụ, niobium carbide ntụ ntụ, na cobalt ntụ ntụ. Njupụta nke YW1 alloy bụ 12.6-13.5g / cm3, njupụta nke YW2 alloy bụ 12.4-13.5g / cm3, na njupụta nke YW3 alloy bụ 12.4-13.3g / cm3.

N'ihi nnukwu njupụta ya, carbide cimented nwere ike mee ka ọ bụrụ ngwaahịa dị iche iche, dị ka igwe counterweights, mkpanaka na-ebu ibu nke a na-eji na-arụ ọrụ dị ka mmanụ, pendulums elekere, ballasts maka ịkwọ ụgbọ mmiri, ịkwọ ụgbọ mmiri, wdg. Counterweights, counterweights ụgbọ elu, wdg. , nke nwere ike hụ na nguzozi nke ihe dị na ọnọdụ na-arụ ọrụ ma ọ bụ kwụ ọtọ, ma ọ bụ chekwaa oke ọrụ nke ndị ọrụ.

Ihe na-akpata njupụta nke tungsten carbide

Njupụta metụtara ihe mejupụtara, oke akụrụngwa, microstructure, usoro mmepụta, paramita usoro, na ihe ndị ọzọ. N'ikwu okwu n'ozuzu, mpaghara ngwa nke cemented carbides nwere njupụta dị iche iche dịkwa iche iche. Ndị na-esonụ na-ebutekarị ihe ndị na-emetụta njupụta alloy.

1. Ihe mejupụtara

Cemented carbide nwere ike mejupụtara ntụ ntụ abụọ, tungsten carbide ntụ ntụ (WC ntụ ntụ) na ntụ ntụ ntụ (Co ntụ ntụ), ma ọ bụ ntụ ntụ atọ: WC ntụ ntụ, TiC ntụ ntụ (titanium carbide ntụ ntụ) na Co ntụ ntụ, ma ọ bụ ọbụna WC ntụ ntụ. Ntụ ntụ, TiC ntụ ntụ, TaC ntụ ntụ (tantalum carbide ntụ ntụ), NbC ntụ ntụ (niobium carbide ntụ ntụ), na Co ntụ ntụ. N'ihi na dị iche iche mejupụtara nke alloy ihe, njupụta nke alloy dị iche iche, ma n'ụzọ ndị yiri: njupụta nke YG6 alloy bụ 14.5-14.9g / cm³, njupụta nke alloy YT5 bụ 12.5-13.2g /. cm³, na njupụta nke alloy YW1 bụ 12.6-13.5g/cm³.

N'ikwu okwu n'ozuzu, njupụta nke tungsten-cobalt (YG) simented carbide na-abawanye na mmụba nke ọdịnaya ntụ ntụ WC. Dịka ọmụmaatụ, njupụta nke alloy na ọdịnaya ntụ ntụ WC nke 94% (YG6 alloy) bụ 14.5-14.9g/cm³, yana ọdịnaya ntụ ntụ WC Njupụta nke 85% alloy (YG15 alloy)bụ 13.9-14.2g/cm³.

Njupụta nke tungsten-titanium-cobalt (YT) siri ike alloys na-ebelata na mmụba nke ọdịnaya ntụ ntụ TiC. Dịka ọmụmaatụ, njupụta alloys nwere ọdịnaya ntụ ntụ TiC nke 5% (YT5 alloy) bụ 12.5-13.2g/cm³, yana ọdịnaya ntụ ntụ TiC bụ 15%. Njupụta nke alloy (YT15 alloy) bụ 11.0-11.7g/cm³.

2. Microstructure

A na-ebute porosity nke ọma site na pores na shrinkage na ọ bụ ihe dị mkpa na-egosi maka ikpebi àgwà nke cemented carbide. Isi ihe mere e ji emepụta pores carbide cimented gụnyere oke ọkụ, ihe ntinye nke organic, ntinye ígwè, ihe ndị na-adịghị mma na-akụda, na ndị na-emepụta ihe na-adịghị mma.

N'ihi ọnụnọ nke pores, njupụta n'ezie nke alloy bụ ihe na-erughị usoro iwu. Ọnụ ọgụgụ buru ibu ma ọ bụ karịa, ka alloy na-adị obere ka ọ dị arọ.

3. Usoro mmepụta

Usoro mmepụta na-agụnye usoro ntụ ntụ ntụ na teknụzụ ịkpụzi injection. Ọdịiche dị ka carburizing, ọkụ na-ere ọkụ, ihe na-adịghị mma, na-agbapụta, peeling, na uncompacting n'oge ịpị na sintering ga-eduga ná mbelata nke njupụta nke cemented carbide.

4. Ebe ọrụ

N'ikwu okwu n'ozuzu, na mgbanwe nke okpomọkụ ma ọ bụ nrụgide, olu ma ọ bụ njupụta nke alloy ga-agbanwekwa kwekọrọ, ma mgbanwe ahụ dị ntakịrị ma nwee ike ileghara ya anya.

Ọ bụrụ na ị nwere mmasị na ngwaahịa tungsten carbide ma chọọ ozi ndị ọzọ na nkọwa, ị nwere ike ịkpọtụrụ anyị.
