Amagambo yerekeye Tungsten Carbide

Hamwe niterambere ryikoranabuhanga, abantu biruka ibikoresho byiza, nibikoresho byo kubaka no kubucuruzi. Muri iki kirere, karbide ya tungsten igira uruhare runini mu nganda zigezweho. Kandi muriyi ngingo, hazatangizwa amagambo amwe yerekeranye na tungsten karbide.

1. Carbide ya sima

Carbide ya sima isobanura ibintu byacuzwe bigizwe na karbide yicyuma cyangiritse hamwe nicyuma gihuza ibyuma. Muri carbide yicyuma, tungsten karbide, titanium karbide, tantalum karbide, nibindi nibindi birimo karbide zikoreshwa cyane. Kandi ibyuma bikoreshwa cyane ni ifu ya cobalt, nibindi byuma bifata ibyuma nka nikel, nicyuma, nabyo bizakoreshwa rimwe na rimwe.

2. Tungsten karbide

Carbide ya Tungsten ni ubwoko bwa karbide ya sima, igizwe nifu ya karubide ya tungsten hamwe nu byuma. Hamwe no gushonga cyane, ibicuruzwa bya tungsten ntibishobora gukorwa nkibindi bikoresho. Ifu ya metallurgie nuburyo busanzwe bwo gukora ibicuruzwa bya tungsten karbide. Hamwe na atome ya tungsten na atome ya karubone, ibicuruzwa bya tungsten karbide bifite ibintu byinshi byiza, bituma biba ibikoresho bizwi cyane mubikorwa bigezweho.

3. Ubucucike

Ubucucike bivuga igipimo cya misa nubunini bwibikoresho. Ingano yacyo nayo irimo ingano ya pore mubikoresho.

Mubicuruzwa bya tungsten karbide, cobalt cyangwa ibindi byuma birahari. Urwego rusanzwe rwa tungsten karbide YG8, rurimo 8% cobalt, rufite ubucucike bwa 14.8g / cm3. Kubwibyo, uko ibirimo cobalt biri muri tungsten-cobalt bivanze, ubwinshi muri rusange buzagabanuka.

4. Gukomera

Gukomera bivuga ubushobozi bwibikoresho byo kurwanya ihindagurika rya plastiki. Ubukomezi bwa Vickers hamwe nubukomezi bwa Rockwell mubisanzwe bikoreshwa mugupima ubukana bwibicuruzwa bya tungsten.

Gukomera kwa Vickers gukoreshwa cyane mumahanga. Ubu buryo bwo gupima ubukana bwerekana agaciro gakomeye kabonetse mugupima ubunini bwa indentation ukoresheje diyama kugirango yinjire hejuru yicyitegererezo mugihe runaka cyumutwaro.

Gukomera kwa Rockwell nubundi buryo bwo gupima ubukana bukunze gukoreshwa. Ipima ubukana ikoresheje ubujyakuzimu bwa cone isanzwe ya diyama.

Byombi uburyo bwo gupima ubukana bwa Vickers hamwe nuburyo bwo gupima ubukana bwa Rockwell burashobora gukoreshwa mugupima ubukana bwa karbide ya sima, kandi byombi birashobora guhinduka.

Ubukomere bwa karubide ya tungsten iri hagati ya 85 HRA na 90 HRA. Urwego rusanzwe rwa tungsten karbide, YG8, rufite ubukana bwa 89.5 HRA. Igicuruzwa cya tungsten karbide gifite ubukana bwinshi kirashobora kwihanganira ingaruka no kwambara neza, kuburyo gishobora gukora igihe kirekire. Nkumuhuza, cobalt nkeya itera gukomera neza. Kandi karubone yo hasi irashobora gutuma tungsten karbide ikomera. Ariko decarbonisation irashobora gutuma karbide ya tungsten yoroshye kwangirika. Mubisanzwe, karbide nziza ya tungsten izongera ubukana bwayo.

5. Kunama imbaraga

Icyitegererezo cyikubye nkigikoresho gishyigikiwe gusa kumurongo ibiri, kandi umutwaro ushyirwa kumurongo wo hagati wibice bibiri kugeza icyitegererezo kimenetse. Agaciro kabaruwe na formulaire ihindagurika ikoreshwa ukurikije umutwaro ukenewe kumeneka hamwe nu gice cyambukiranya icyitegererezo. Bizwi kandi nka transvers guturika imbaraga cyangwa kunama.

Muri WC-Co tungsten karbide, imbaraga za flexural ziyongera hamwe no kwiyongera kwa cobalt yibintu bya tungsten-cobalt, ariko iyo ibirimo cobalt bigera kuri 15%, imbaraga za flexural zigera ku giciro kinini, hanyuma zigatangira kumanuka.

Imbaraga zunama zapimwe nimpuzandengo yagaciro kapimwe. Agaciro nako kazahinduka nka geometrie yikigereranyo, imiterere yubuso, imihangayiko yimbere, hamwe nudusembwa twimbere two guhindura ibintu. Kubwibyo, imbaraga zihindagurika nigipimo cyimbaraga gusa, kandi imbaraga zingirakamaro ntizishobora gukoreshwank'ishingiro ryo guhitamo ibikoresho.

6. Guhindura imbaraga zo guturika

Imbaraga zo guturika imbaraga nubushobozi bwa tungsten karbide yo kurwanya kunama. Carbide ya Tungsten hamwe nimbaraga nziza zo guturika ziragoye cyane kwangiza ingaruka. Carbide nziza ya tungsten ifite imbaraga zo gutandukana neza. Kandi iyo ibice bya karubide ya tungsten bigabanijwe neza, transvers iba nziza, kandi karbide ya tungsten ntabwo byoroshye kwangiza. Imbaraga zo guturika za YG8 tungsten carbide yibicuruzwa ni MPa 2200.

7. Imbaraga zagahato

Imbaraga zo guhatira ni imbaraga za rukuruzi zisigaye zapimwe no gukwega ibintu bya magneti muri karbide ya sima kugeza byuzuye hanyuma bikayitesha agaciro.

Hariho isano itaziguye hagati yubunini buringaniye bwa sima ya karbide ya sima nimbaraga zo guhatira. Impuzandengo yingero zingana zingana na magneti, niko imbaraga zagahato zifite agaciro. Muri laboratoire, imbaraga zagahato zipimishwa nimbaraga zagahato.

Nibisobanuro bya tungsten karbide nibiranga. Andi magambo menshi nayo azatangizwa mu ngingo zikurikira.

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