Indlela Yokukhiqiza I-Tungsten Carbide

Sonke siyazi ukuthi i-carbide alloys yenziwe nge-tungsten carbide, kodwa ingabe uyayazi imfihlo yokuthi ungayikhiqiza kanjani? Lesi siqephu singase sikunikeze impendulo. Ukukhiqizwa kwe-carbide enosimende ukuxuba i-carbide powder ne-bond powder ngesilinganiso esithile, ukucindezela kube izimo ezihlukahlukene, bese u-semi-sintered. Izinga lokushisa le-sintering liyi-1300-1500 ° C.

Lapho kukhiqizwa i-carbide enosimende, impushana yezinto eluhlaza ekhethiwe inosayizi wezinhlayiyana phakathi kwe-1 ne-2 microns, futhi ubumsulwa buphezulu kakhulu. Izimpushana zezinto ezingavuthiwe zixutshwa ngokwesilinganiso esibekiwe sokubunjwa, zingafinyelela amamaki ahlukene ngokwezilinganiso ezihlukene ze-WC kanye nempushana yebhondi. Khona-ke i-medium yengezwa emshinini webhola omanzi ukuze ube manzi-uwagaye ukuze ahlanganiswe ngokugcwele futhi agaywe. Ngemuva kokumisa nokuhlunga, i-ejenti yokwakha yengezwa, futhi ingxube iyomiswa futhi ihlungwe. Okulandelayo, lapho ingxube ihlutshiwe futhi icindezelwe, futhi ishisiswe eduze nendawo yokuncibilika yensimbi ye-binder (1300-1500 ° C), isigaba esiqinile kanye nensimbi ye-binder izokwakha i-eutectic alloy. Ngemva kokupholisa, kwakheka yonke into eqinile. Ukuqina kwe-carbide enosimende kuncike kokuqukethwe kwe-WC nosayizi wokusanhlamvu, okungukuthi, ingxenye eyengeziwe ye-WC kanye nokucolisa okusanhlamvu, kukhulu ubulukhuni. Ukuqina kwethuluzi le-carbide kunqunywa insimbi yebhondi. Ukuphakama kokuqukethwe kwensimbi yebhondi, kuyanda amandla okugoba.

Ucabanga ukuthi ngemuva kokupholisa umkhiqizo usuwenziwe ngokugcwele?

Impendulo ithi cha! Ngemva kwalokho, izothunyelwa izivivinyo eziningi. Imikhiqizo ye-Tungsten carbide ingabonisa umehluko wezakhiwo zemishini ezingxenyeni zamakhemikhali, izakhiwo zezicubu, kanye nenqubo yokwelapha ukushisa. Ngakho-ke, ukuhlolwa kokuqina kusetshenziswa kabanzi ekuhlolweni kwezakhiwo ze-carbide, ezingaqondisa ukunemba kwenqubo yokwelapha ukushisa kanye nokucwaninga kwezinto ezintsha. Ukutholwa kokuqina kwe-tungsten carbide kusetshenziswa kakhulu isihloli sokuqina se-Rockwell ukuze kuhlolwe amanani okuqina e-HRA. Ukuhlolwa kunomumo oqinile kanye nokuguquguquka kwe-dimensional kwesiqephu sokuhlola ngokusebenza kahle okuphezulu.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
