Tungsten Carbide Blade
Hamwe noguhitamo neza, ingano ya submicron ingano ya tungsten karbide irashobora gukarishwa kugeza kumurongo wogosha utarimo ubugome busanzwe bujyanye na karbide isanzwe. Nubwo idashobora kwihanganira ibyuma, karbide irwanya kwambara cyane, hamwe nuburemere bungana na Rc 75-80. Ubuzima bwa blade byibura 50X ibyuma bisanzwe birashobora gutegurwa mugihe birinze gukata no kumeneka.
Nkuko mubyerekeranye no guhitamo ibyuma, guhitamo icyiciro cyiza cya tungsten karbide (WC) ninzira igoye irimo guhitamo kubangamira hagati yo kwambara-gukomera no gukomera / guhungabana. Carbide ya tungsten ya sima ikozwe no gucumura (ku bushyuhe bwo hejuru) ikomatanya ifu ya karbide ya tungsten hamwe nifu ya cobalt (Co), icyuma cyangiza ikora nka "binder" kubice bya karubide bikabije cyane. Ubushyuhe bwibikorwa byo gucumura ntabwo burimo reaction yibigize 2, ahubwo bitera cobalt kugera kumiterere-y-amazi hanyuma igahinduka nka matrike ikomatanya ibice bya WC (bitatewe nubushyuhe). Ibipimo bibiri, aribyo igipimo cya Cobalt na WC nubunini bwa WC, bigenzura cyane ibintu byinshi byumutungo wa "sima ya tungsten carbide" yavuyemo.
Kugaragaza ingano nini ya WC hamwe nijanisha ryinshi rya Cobalt bizatanga igice cyihanganira cyane (nimbaraga zikomeye). Ingano nziza ya WC (kubwibyo, uko ubuso bwa WC bugomba gutwikirwa na Cobalt) hamwe na Cobalt nkeya ikoreshwa, bigoye kandi birwanya kwambara igice cyavuyemo kizahinduka. Kugirango ubone imikorere myiza iva kuri karbide nkibikoresho byicyuma, ni ngombwa kwirinda kunanirwa hakiri kare biterwa no gutemagura cyangwa kumeneka, mugihe icyarimwe wizeza ko ushobora kwambara neza.
Nkikintu gifatika, umusaruro wogukata cyane, gukata impande zose zitegeka ko karbide nziza yimbuto ikoreshwa mugukoresha ibyuma (kugirango wirinde inkoni nini nimpande zikomeye). Urebye ikoreshwa rya karbide ifite impuzandengo yingano ya micron 1 cyangwa munsi yayo, imikorere ya karbide; kubwibyo, ihinduka ahanini na% ya Cobalt nu nkombe ya geometrie yagenwe. Gukata porogaramu zirimo imitwaro iringaniye kandi iremereye nibyiza gukemurwa no kwerekana 12-15 ku ijana Cobalt hamwe na geometrie ifite impande zingana zingana na 40º. Porogaramu zirimo imitwaro yoroheje kandi igashyira premium kubuzima burebure ni abakandida beza ba karbide irimo 6-9% cobalt kandi ifite impande zingana zingana na 30-35º.
HUAXIN CARBIDE ihagaze neza kugirango igufashe kugera ku ntera nziza yimitungo izagufasha kubona imikorere myinshi uhereye kuri karbide yawe.
HUAXIN CARBIDE itanga ihitamo rya karbide urwembe rwogosha
