Ubucucike bwa Carbide ya Tungsten

Tungsten Carbide, izwi nk'amenyo y'inganda, ni ibicuruzwa bisanzwe. Irazwi cyane kubera ibyiza byayo birimo ubukana bwinshi, imbaraga nyinshi, ubwinshi bwinshi, kurwanya kwambara, hamwe no kurwanya ruswa, ku buryo, ishobora gukorwa mu bice bitandukanye byo gucukura, gukata, ibikoresho byo gucukura amabuye, ibikoresho byo gucukura amabuye, kwambara ibice, imirongo ya silinderi , n'ibindi. Mu nganda, tuzakoresha ibipimo byinshi kugirango tugerageze kandi tumenye ko ibicuruzwa bya tungsten karbide bifite ubuziranenge. Muri iyi ngingo, ibyingenzi byingenzi biranga umubiri, ubucucike, bizaganirwaho.

Ubucucike ni iki?

Ubucucike nigitekerezo cyingenzi cyumutungo wububiko kugirango werekane ubwinshi bwa karbide ya sima kuri buri mubare. Ingano twavuze hano, ikubiyemo ingano ya pore mubikoresho. Ukurikije gahunda mpuzamahanga y’ibice hamwe n’ibipimo byo gupima byemewe n’Ubushinwa, ubucucike bugereranywa n’ikimenyetso ρ, naho ubucucike ni kg / m3.

Ubucucike bwa karubide ya tungsten

Muburyo bumwe bwo gukora hamwe nibipimo bimwe, ubucucike bwa karbide ya sima izahinduka hamwe no guhindura imiterere yimiti cyangwa guhindura igipimo cyibikoresho fatizo.

Ibice byingenzi bigize urutonde rwa YG sima ya karbide ni ifu ya tungsten karbide nifu ya cobalt. Mubihe bimwe, nkuko ibirimo cobalt byiyongera, ubucucike bwa alloy buragabanuka, ariko iyo agaciro gakomeye kageze, intera ihindagurika ni nto. Ubucucike bwa YG6 buvanze ni 14.5-14.9g / cm3, ubucucike bwa YG15 ni 13.9-14.2g / cm3, n'ubucucike bwa YG20 ni 13.4-13.7g / cm3.

Ibice byingenzi bigize urutonde rwa YT sima ya karbide ni ifu ya tungsten karbide, ifu ya titanium, nifu ya cobalt. Mubihe bimwe, nkuko ibirimo ifu ya titanium karbide yiyongera, ubucucike bwumusemburo buragabanuka. Ubucucike bwa YT5 12.5-13.2g / cm3, Ubucucike bwa YT14 11.2-12.0g / cm3, Ubucucike bwa YT15 11.0-11.7g / cm3

Ibice byingenzi bigize urukurikirane rwa YW sima ya karbide ni ifu ya karubide ya tungsten, ifu ya karubide ya titanium, ifu ya tantalum karbide, ifu ya niobium, nifu ya cobalt. Ubucucike bwa YW1 buvanze ni 12.6-13.5g / cm3, ubucucike bwa YW2 ni 12.4-13.5g / cm3, n'ubucucike bwa YW3 ni 12.4-13.3g / cm3.

Bitewe n'ubucucike bwinshi, karbide ya sima irashobora gukorwa mubicuruzwa bitandukanye, nk'ibikoresho byo kurwanya imashini, inkoni ziremereye zikoreshwa mu nganda zicukura nka peteroli, pendulumu y'isaha, ballast yo kugenda, ubwato, n'ibindi. , Irashobora kwemeza kuringaniza ibintu mubikorwa cyangwa bihagaze neza, cyangwa bikiza cyane umurimo w'abakozi.

Icyitonderwa: Ubucucike bwifu ya karubide ya tungsten ni 15,63g / cm3, ubwinshi bwifu ya cobalt ni 8.9g / cm3, ubucucike bwifu ya karubide ya titanium ni 4.93g / cm3, ubucucike bwifu ya tantalum karbide ni 14.3g / cm3, n'ubucucike bw'ifu ya niobium karbide ni 8.47g / cm3.

Ibintu bya tungsten karbide yuzuye

Ubucucike bujyanye nibintu bigize ibintu, igipimo fatizo cyibikoresho, microstructure, inzira yumusaruro, ibipimo ngenderwaho, nibindi bintu. Muri rusange, imirima ikoreshwa ya sima ya karbide ifite ubucucike butandukanye nayo iratandukanye. Ibikurikira byerekana cyane cyane ibintu bitera ubucucike.

1. Ibikoresho

Carbide ya sima irashobora kuba igizwe nifu ebyiri, ifu ya karubide ya tungsten (ifu ya WC) nifu ya cobalt (ifu ya Co), cyangwa ifu itatu: ifu ya WC, ifu ya TiC (ifu ya titanium karbide) nifu ya Co, cyangwa ifu ya WC. Ifu, ifu ya TiC, ifu ya TaC (ifu ya tantalum karbide), ifu ya NBC (ifu ya niobium karbide), nifu ya Co. Bitewe nuburyo butandukanye bwibikoresho bivangwa, ubucucike bwuruvange buratandukanye, ariko ibyiciro birasa: ubucucike bwumusemburo wa YG6 ni 14.5-14.9g / cm³, ubucucike bwa YT5 ni 12.5-13.2g / cm³, n'ubucucike bwa YW1ni 12.6-13.5g / cm³.

Muri rusange, ubucucike bwa tungsten-cobalt (YG) sima ya karbide yiyongera hamwe no kwiyongera kwifu ya WC. Kurugero, ubucucike bwuruvange hamwe nifu ya WC ya 94% (YG6 alloy) ni 14.5-14.9g / cm³, naho ifu ya WC Ubucucike bwa 85% alloy (YG15 alloy) ni 13.9-14.2g / cm³.

Ubucucike bwa tungsten-titanium-cobalt (YT) ibinini bigoye bigabanuka hamwe no kwiyongera kwifu ya TiC. Kurugero, ubwinshi bwimvange hamwe nifu ya TiC ya 5% (YT5 alloy) ni 12.5-13.2g / cm³, naho ifu ya TiC ni 15%. Ubucucike bw'amavuta (YT15 alloy) ni 11.0-11.7g / cm³.

2. Microstructure

Ububabare buterwa ahanini na pore no kugabanuka kandi ni ikimenyetso cyingenzi cyo gusuzuma ubwiza bwa karbide ya sima. Impamvu nyamukuru zitera gushiraho imyanda ya karbide ya sima harimo gutwika cyane, gushyiramo ibinyabuzima, gushyiramo ibyuma, ibintu bidahwitse, hamwe nuburyo bwo kubumba.

Bitewe no kuba hari imyenge, ubucucike nyabwo bwa alloy ntabwo buri munsi yubucucike. Ibinini binini cyangwa byinshi, ubucucike buke buri ku buremere bwatanzwe.

3. Uburyo bwo gukora

Igikorwa cyo kubyaza umusaruro kirimo ifu ya metallurgie hamwe nubuhanga bwo gutera inshinge. Inenge nka carburizing, gutwika munsi, kubeshya, kubyimba, gukuramo, no kudakora mugihe cyo gukanda no gucumura bizatuma igabanuka ryubwinshi bwa karbide ya sima.

4. Ibidukikije

Muri rusange, hamwe nihinduka ryubushyuhe cyangwa umuvuduko, ingano cyangwa ubucucike bwuruvange nabyo bizahinduka bihuye, ariko impinduka ni nto kandi irashobora kwirengagizwa.

Niba ushimishijwe nibicuruzwa bya tungsten ukaba ushaka amakuru arambuye, urashobora kutwandikira ukoresheje terefone cyangwa amabaruwa ibumoso, cyangwa UKOHEREZA MAIL US hepfo yurupapuro.
