Icyuma cya tungsten, izina ryacyo rikomoka mu gisuwede - tung (uburemere) na sten (ibuye) rikoreshwa cyane cyane muburyo bwa sima ya tungsten karbide.Carbide ya sima cyangwa ibyuma bikomeye nkuko bakunze kuyita ni urwego rwibikoresho bikozwe na 'cementing' ibinyampeke bya tungsten karbide muri materix ihuza materi ya cobalt hamwe nuburyo bwitwa feri ya sinteri.
Muri iki gihe ingano ya tungsten karbide ingano iratandukanye kuva kuri microne 0.5 kugeza kuri micron zirenga 5 hamwe na cobalt ishobora kugera kuri 30% kuburemere.Mubyongeyeho, kongeramo izindi karbide nabyo birashobora guhindura imiterere yanyuma.
Igisubizo nicyiciro cyibikoresho birangwa na
Imbaraga nyinshi
Gukomera
Gukomera cyane
Muguhindura ingano yubunini bwa karubide ya tungsten nibirimo cobalt muri matrike, no kongeramo ibindi bikoresho, injeniyeri barashobora kubona icyiciro cyibikoresho imitungo yabo ishobora guhuzwa nibikorwa bitandukanye byubuhanga.Ibi birimo ibikoresho byikoranabuhanga bihanitse, kwambara ibice nibikoresho byo kubaka ubucukuzi bw'amabuye y'agaciro na peteroli na gaze.
Ibicuruzwa bya Tungsten Carbide nibisubizo byifu ya metallurgie ikoresha cyane cyane karbide ya tungsten hamwe nifu ya cobalt.Mubisanzwe, ibice bivanze bizava kuri 4% cobalt kugeza 30% cobalt.
Impamvu nyamukuru yo guhitamo gukoresha karbide ya tungsten nugukoresha inyungu zikomeye ibyo bikoresho byerekana bityo bikadindiza igipimo cyimyambarire yibigize.Kubwamahirwe, igihano kijyanye no gukomera ni ukubura gukomera cyangwa imbaraga.Kubwamahirwe, muguhitamo ibihimbano birimo ibintu byinshi bya cobalt, imbaraga zirashobora kugerwaho hamwe no gukomera.
Hitamo ibintu bike bya cobalt kubisabwa aho ibice bitazaba byitezwe ko bigira ingaruka, bigera ku gukomera gukomeye, kwihanganira kwambara cyane.
Hitamo ibintu byinshi bya cobalt niba porogaramu irimo guhungabana cyangwa ingaruka hanyuma ugere ku kurwanya kwambara kurenza ibindi bikoresho byinshi bishobora gutanga, hamwe nubushobozi bwo kurwanya ibyangiritse.
