Cemented carbideihupfu hwesimbi inogadzirwa kubva kucarbide (wc, tic) micron-saizi poda yekuomarara simbi ine cobalt (co) kana nickel (ni) uye molybdenum (mo) sebhainda, yakanyudzwa muvira revacuum kana muchoto wekudzikisa hydrogen. .
Kana kugadzirasimende carbide, ukuru hwehupfu hwehupfu hwakasarudzwa huri pakati pe1 ne2 microns, uye kuchena kwakanyanya.Zvinhu zvakasvibirira zvinoiswa muchikamu chakatarwa, chinowedzerwa kudoro kana zvimwe zvinodhiya mune bhora rakanyorova, kuitira kuti zvinyatso kusanganiswa, kupwanywa, kuomeswa, kusefa uye kuwedzerwa kune wakisi kana chingamu uye mamwe marudzi emhando yekuumba, wobva waoma. uye sefa kuita musanganiswa.Zvadaro, musanganiswa wacho unogadzirwa negranulated, kumanikidzwa, uye kupisa kusvika pedyo nekunyunguduka kwesimbi yakasungwa (1300 ~ 1500 ℃), chikamu chakaomeswa uye simbi yakasungwa inoumba eutectic alloy.
Mushure mekutonhora, zvikamu zvakaomeswa zvinogoverwa mugridi inoumbwa nesimbi dzakasungirirwa, dzakanyatsobatanidzwa kune imwe neimwe kuti dziite yakasimba yakazara.Kuomarara kwesamende carbide kunoenderana nekuoma kwechikamu uye saizi yezviyo, kureva kukwira kwechikamu chekuomesa uye nekunakisa saizi yezviyo, ndiko kukura kuoma.Kuoma kwesimende carbideinotemerwa nesimbi inosungirirwa, uye nekukwira kwesimbi yekubatanidza, ndiko kukura kwesimba rekukombama.
