Ku-powder metallurgy,inqubo yokukhiqiza i-powder metallurgynoma isetshenziswe njengempahla eluhlaza ukuze kwakhiwe izinto zensimbi, izinto eziyinhlanganisela, kanye nemikhiqizo ehlukahlukene ngemva kokwakhiwa nokushiswa. I-powder metallurgy, okuyingxenye yei-powder metal sintering, ihlobene nokwakhiwa kwezitsha zobumba. Ngenxa yalokhu, inqwaba yeziko lokucwilisa izinsimbi zensimbi eyimpushane nazo zingasetshenziswa ukwenza izinto zobumba.
1. Ukulungiswa kwempushana yezinto ezingavuthiwe. Izindlela zokugaya ezikhona zingahlukaniswa cishe zibe izigaba ezimbili: izindlela zemishini nezindlela ze-physicochemical. Izindlela zemishini zingahlukaniswa zibe: ukuchotshozwa kwemishini kanye ne-atomization; Izindlela zomzimba nezamakhemikhali zihlukaniswe ngendlela ye-electrochemical corrosion, indlela yokunciphisa, indlela yamakhemikhali, indlela yokunciphisa-amakhemikhali, indlela yokubeka umhwamuko, indlela yokubeka uketshezi kanye nendlela ye-electrolysis. Phakathi kwazo, indlela yokunciphisa, indlela ye-atomization kanye nendlela ye-electrolysis isetshenziswa kabanzi.
2. Impushana ibunjwa ibe yinto engenalutho enesimo esidingekayo. Inhloso yokubumba ukunikeza okungenalutho ukuma nobukhulu obuthile, nokuwunikeza ukuminyana namandla athile. Izindlela zokwakha zihlukaniswa ngokuyisisekelo zibe ukwakha ingcindezi kanye nokwakheka okungeyona ingcindezi. Ukubumba ingcindezi kusetshenziswa kakhulu ekubumbeni ingcindezi.
3. billet sintering. Isinyathelo esibalulekile sokungenai-powder metallurgy sinteringubuchwepheshe besithando somlilo buyashisa. I-billet eluhlaza ingacwiliswa ngemuva kokuthi yenziwe ukuze inikeze izici ezifiselekayo zomshini nezomzimba. I-unit sintering kanye ne-multi-system sintering yizigaba ezimbili zokucula. Izinga lokushisa le-sintering liphansi kunephuzu lokuncibilika lensimbi nengxubevange esetshenziselwa ukufakwa kwesimo esiqinile sohlelo lweyunithi kanye nesistimu yezinto eziningi. Izinga lokushisa le-sintering lesigaba soketshezi se-sintering yamasistimu ezingxenye eziningi ngokuvamile liphakeme kunephuzu lokuncibilika lengxenye ye-fusible kodwa liphansi kunephuzu lokuncibilika lengxenye ye-refractory. Kunezindlela ezikhethekile zokuthungatha ezifana nokudubula okuxekethile, ukucwiliswa emanzini okuncibilika, nokucindezela okushisayo ngaphezu kokushisa okujwayelekile.
4. ukulandela ukwelashwa komkhiqizo. Ukulandela i-sintering, izindlela ezahlukahlukene zokucubungula zingasetshenziswa ngokuya ngezidingo zomkhiqizo wokugcina. njengokwenza imishini, ukwelashwa kokushisa, i-electroplating, ukuqeda, njalonjalo. Ukwengeza, eminyakeni yamuva nje, izinto zesithando somlilo se-powder metallurgy ziye zacutshungulwa kusetshenziswa ukugoqa, ukufoja, nezinye izindlela ezintsha, futhi imiphumela engcono kakhulu itholakele.
