Amagambo akoreshwa cyane (1)

Kugira ngo dutezimbere gusobanukirwa na raporo hamwe nubuhanga bwa tekiniki kubyerekeye gukomera, guhuza imvugo, no gusobanura ibisobanuro byamagambo ya tekinike mu ngingo, turi hano kugirango twige amagambo akomeye.

Tungsten Carbide

Tungsten karbide bivuga ibicumuro bigizwe na karbide yicyuma cyangiritse hamwe nicyuma. Muri karbide yicyuma ikoreshwa ubu, karbide ya tungsten (WC), titanium karbide (TiC), na karbide ya tantalum (TaC) nibintu bikunze kugaragara. Icyuma cya Cobalt gikoreshwa cyane mubikorwa bya sima ya sima nka binder. Kubintu bimwe bidasanzwe, ibyuma bihuza nka nikel (Ni) nicyuma (Fe) nabyo birashobora gukoreshwa.

Ubucucike

Ubucucike bivuga igipimo cya misa-nubunini bwibintu, nabyo byitwa uburemere bwihariye. Ingano yacyo nayo irimo ingano ya pore mubikoresho. Carbide ya Tungsten (WC) ifite ubucucike bwa 15.7 g / cm³ na cobalt (Co) ifite ubucucike bwa 8.9 g / cm³. Kubwibyo, nkuko ibirimo cobalt (Co) biri muri tungsten-cobalt alloys (WC-Co) bigabanuka, ubwinshi muri rusange buziyongera. Nubwo ubucucike bwa karubide ya titanium (TiC) buri munsi ya karubide ya tungsten, ni 4.9 g / cm3。 Niba TiC cyangwa ibindi bikoresho bitarimo ubucucike byongeweho, ubwinshi muri rusange buzagabanuka. Hamwe nibintu bimwe na bimwe bya chimique yibikoresho, kwiyongera kwa pore mubikoresho bivamo kugabanuka kwubucucike.

Gukomera

Gukomera bivuga ubushobozi bwibikoresho byo kurwanya plastike.

Gukomera kwa Vickers (HV) bikoreshwa cyane mumahanga. Ubu buryo bwo gupima ubukana bivuga agaciro gakomeye kabonetse ukoresheje diyama kugirango yinjire hejuru yicyitegererezo kugirango bapime ubunini bwa indentation munsi yumutwaro runaka. Gukomera kwa Rockwell (HRA) nubundi buryo bukoreshwa muburyo bwo gupima ubukana. Ikoresha ubujyakuzimu bwa diyama isanzwe kugirango ipime ubukana. Byombi gukomera kwa Vickers hamwe no gukomera kwa Rockwell birashobora gukoreshwa mugupima ubukana bwa karbide ya sima, kandi byombi birashobora guhinduka.

Imbaraga

Imbaraga zunama zizwi kandi nka transvers yameneka imbaraga cyangwa imbaraga zidasanzwe. Amavuta akomeye yongeweho nkibikoresho byoroheje bishyigikira kuri pivot ebyiri, hanyuma umutwaro ushyirwa kumurongo wo hagati ya pivot zombi kugeza igihe ivanze rikomeye. Indangagaciro zibarwa uhereye kumirongo ikoreshwa zikoreshwa mumitwaro isabwa kumeneka, hamwe nu gice cyambukiranya icyitegererezo. Muri tungsten-cobalt alloys (WC-Co), imbaraga za flexural ziyongera hamwe na cobalt (Co) muri tungsten-cobalt, ariko imbaraga za flexural zigera kuri byinshi mugihe cobalt (Co) igera kuri 15%. Imbaraga zihindagurika zapimwe no kugereranya ibipimo byinshi. Agaciro nako kazatandukana na geometrie yicyitegererezo, imiterere yubuso (ubworoherane), guhangayika kwimbere, hamwe nubusembwa bwimbere bwibintu. Kubwibyo, imbaraga zidasanzwe ni igipimo cyimbaraga gusa, kandi indangagaciro zingirakamaro ntizishobora gukoreshwa nkifatizo ryo guhitamo ibintu.

Ubwoba

Carbide ya sima ikorwa na powder metallurgie mugukanda no gucumura. Bitewe nuburyo bwuburyo, gushakisha urugero rwinshi bishobora kuguma mumiterere yibicuruzwa.

Kugabanuka kwa porosity birashobora kunoza neza imikorere yibicuruzwa. Uburyo bwo gucumura igitutu nuburyo bwiza bwo kugabanya ububobere.
