Iyiphi indlela ye-Powder metallurgy sintering

I-powder metallurgyyenziwa ngokukhiqiza impushana, ukubumba ngokucindezela,ukucula, kanye ne-post-processing, kanye ne-sintering ingenye yezinqubo ezibalulekile ze-powder metallurgy. Phakathi nenqubo ye-metal powder sintering, izinhlayiya zempushana kufanele zigeleze, zisakazeke, zincibilike, ziphinde zikhanye kanye nezinye izinqubo zomzimba namakhemikhali. Inqubo iqhubeka igxilisa impushana futhi iqede ezinye noma zonke izimbotshana zayo. Kukhona futhi izindlela eziningana zokuthungatha ze-powder metallurgy sintering. Ngakho-ke, yiziphi izidakamizwa ezisetshenziswa kakhuluizindlela zokugezange-powder metallurgy?

Izindlela ze-powder metallurgy sintering ngokuvamile ziwela ezigabeni ezilandelayo:

1. Isigaba samanzi sintering

Uma kunezingxenye ezimbili noma ngaphezulu ku-compact powder, i-sintering ingenziwa ngaphezu kwendawo yokuncibilika yengxenye ethile, ngakho-ke inani elincane lesigaba se-liquid livela ku-powder compact ngesikhathi sokugcoba.

2. Ukunciphisa ingcindezi

Ngesikhathi se-metal powder sintering, ingcindezi isetshenziswa emzimbeni oyimpushana ukuze kuthuthukiswe inqubo yawo yokuqina. I-pressure sintering kwesinye isikhathi ifana nokucindezela okushisayo, okuyinqubo ehlanganisa ukwakheka nokucwiliswa kwezimpushana ukuze kutholwe izingxenye ezishisayo.

3. Ukwenza kusebenze sintering

Ezinye izinyathelo ezingokomzimba noma zamakhemikhali zamukelwa enqubweni ye-sintering, ukuze izinga lokushisa le-sintering lincishiswe kakhulu, isikhathi se-sintering sifinyezwe kakhulu, futhi ukusebenza komzimba we-sintered kuyathuthukiswa futhi kuthuthukiswe.

4. EDM sintering

Lapho umzimba we-powder ukhiwa futhi ucindezelwe, ugesi oqondile wamanje kanye ne-pulse usetshenziselwa ukukhiqiza i-arc phakathi kwezinhlayiya ze-powder for sintering; ngesikhathi senqubo ye-mim sintering, ingcindezi isetshenziswa kancane kancane kucezu lokusebenza, futhi izinqubo ezimbili zokwenza kanye ne-sintering ziyahlanganiswa.

5. I-powder esiqinile isigaba sintering

Indlela ye-powder sintering lapho impushana exegayo noma ama-compact ingancibiliki ngesikhathi senqubo yokucwilisa. I-Powder solid-phase sintering ingahlukaniswa ngezinhlobo ezimbili: i-unit-system solid-phase sintering kanye ne-multi-system solid-phase sintering ngokuya ngenani lezingxenye.

Okungenhla isingeniso sezindlela ezivamile zokucwilisa i-powder metallurgy.I-Sintering ku-powder metallurgy inqubo yokwelapha eshisa kakhulu ehlanganisa ngokuqhubekayo imizimba yempushana ehlangene noma exekethile ukuze kuthuthukiswe amandla nezinye izakhiwo.

Selokhu yasungulwa, i-Minxin Powder Metallurgy izibophezele ocwaningweni nasekuthuthukisweni, ekukhiqizeni nasekuthengisweni kwe-metal powder pressing kanye nensimbi.ukubumba umjovo we-powder. Iminyaka eyishumi, ithimba le-R&D ligxile ekukhiqizeni i-powder metallurgy enembayo ephezulu: izingxenye ezinembayo amabheringi afakwe uwoyela, izingxenye zesakhiwo, amagiya, izingxenye zensimbi engagqwali eziyimpushana kanye nemikhiqizo ehlukahlukene yokubumba umjovo oyimpushana. Material: uchungechunge zethusi, ithusi uchungechunge iron, iron uchungechunge, ingxubevange steel, insimbi engagqwali zobumba, njll.
