Njengenxalenye ebalulekileyo kwintsimi yoshishino, ukusebenza kakuhle kweqhosha le-tungsten carbide ayinakuhlukaniswa kwinkqubo yokuvelisa.
Eyokuqala kukulungiswa kwezinto eziluhlaza. I-tungsten kunye ne-cobalt cemented carbides zidla ngokusetyenziselwa ukwenza iqhosha le-tungsten carbide, kunye ne-tungsten carbide, i-cobalt kunye nezinye iipowder zixutywe kumlinganiselo othile. Ezi powders kufuneka zihlolwe kakuhle kwaye zicutshungulwe ukuze kuqinisekiswe ubungakanani be-particle efanayo kunye nokucoceka okuphezulu, ukubeka isiseko senkqubo yokuvelisa elandelayo.
Okulandelayo kuza inqanaba lokubumba umgubo. I-powder edibeneyo icinezelwe phantsi koxinzelelo oluphezulu kwimilo yokuqala yamazinyo e-spherical ngokusebenzisa i-mold ethile. Le nkqubo idinga ulawulo oluchanekileyo loxinzelelo kunye nobushushu ukuqinisekisa ukuxinana okufanayo kunye nemilinganiselo echanekileyo yamazinyo. Nangona umzimba wezinyo elicinezelweyo sele umile ngendlela ethile, lisebuthathaka.
Oku kulandelwa yinkqubo ye-sintering. Umzimba wezinyo le-spherical sintered kwi-high-tempering sintering furnace, kwaye phantsi kwesenzo sobushushu obuphezulu, amasuntswana omgubo asasazeka kwaye adibanise ukwenza isakhiwo esiqinileyo se-carbide. Iiparamitha ezifana nobushushu, ixesha kunye nomoya we-sintering kufuneka zilawulwe ngokuqinileyo ukuqinisekisa ukusebenza kakuhle kwamazinyo. Emva kwe-sintering, iimpawu zamazinyo ebhola ezifana nobunzima, amandla kunye nokuxhatshazwa kokugqoka kuye kwaphuculwa kakhulu.
Ukuze kuphuculwe ngakumbi umgangatho womphezulu kunye nokuchaneka kwamazinyo ebhola, ukucwangciswa okulandelayo kwakhona kwenziwa. Ngokomzekelo, ukugaya, ukupholisa kunye nezinye iinkqubo zisetyenziselwa ukwenza ubuso bamazinyo ebhola bube bushelelezi kunye nobukhulu obuchanekileyo. Kwangaxeshanye, ngokweemfuno ezahlukeneyo zesicelo, amazinyo ebhola anokwagqunywa, njenge-titanium plating, i-titanium nitride plating, njl.njl., Ukuphucula i-anti-wear, anti-corrosion kunye nezinye iipropathi.
Ukuhlolwa komgangatho wenziwa kuyo yonke inkqubo yokuvelisa. Ukususela ekuhlolweni kwezinto eziluhlaza, ukuya kuvavanyo lweemveliso eziphakathi kwinkqubo nganye yokuvelisa, ukuya kuvavanyo lwentsebenzo yemveliso yokugqibela, inyathelo ngalinye lendlela liqinisekisa ukuba umgangatho wamazinyo ajikelezayo udibana nemigangatho echanekileyo. Kuphela ngamazinyo angqukuva aphumelele iimvavanyo ezahlukeneyo anokufakwa kwi-practical application.
