B. Izingxenye zensimbi ezakhiwe

1. Izinzuzo zokufoja:

Shintsha ukugeleza kwezinhlayiyana zezinto ukuze zigeleze ngendlela yengxenye.

Dala izingxenye ezinamandla kunezinye izinqubo zokukhiqiza.Izingxenye ezifojiwe zifaneleka kakhulu ukusetshenziswa ezimeni eziyingozi noma eziphazamisa kakhulu, njengamagiya ezinjini zezimoto.

Ingenziwa ibe yizimo eziningi.

Ingakha izingxenye ezinkulu kakhulu.

Ishibhile ngokuqhathaniswa nokucutshungulwa kwemishini.

2. Okubi kokufoja:

Ukuntuleka kokulawula phezu kwe-microstructure.

Kunesidingo esikhulu sokucutshungulwa kwesibili, okwandisa izindleko nesikhathi sokulethwa kwephrojekthi.

Akunakwenzeka ukukhiqiza ama-porous bearings, ama-carbides anosimende noma izingxenye zensimbi ezixutshwe.

Ngaphandle komshini, izingxenye ezincane ezinemiklamo ebucayi azikwazi ukukhiqizwa

Ukukhiqizwa kwesikhunta kuyabiza, okwenza umnotho wokukhiqiza wesikhashana ungafiseki.

3. Uma ufuna ukukala izinzuzo kanye nebubi bokubumba kanye ne-powder metallurgy, kungase kusho ukuthi ufuna inqubo yokukhiqiza engafinyelela ukusebenza kwezindleko ezifanele.Uma ubheka kakhulu inqubo ngayinye, uyothola ngokwengeziwe lokho kuncike kumazinga wephrojekthi yakho.Ukuqamba kuhle kwezinye izimo, kuyilapho i-PM inhle kwezinye.Ngokweqiniso, kuncike kulokho ofuna ukukufeza.Ngokuthuthuka kobuchwepheshe kanye nenqubo, ubuchwepheshe be-powder metallurgy buye bathuthukiswa ngokuzumayo nemingcele.Manje ungenza izinto ezimangalisayo ngezinsimbi eziyimpuphu-bona ukuthi abakhiqizi bezinga lokushisa eliphakeme le-sintering benzani.Kwezinye izimo, ukukhulisa izinga lokushisa le-sintering ngo-100° ukuya ku-300°F kungaveza imiphumela engcono kakhulu kulezi zindawo ezilandelayo: amandla, amandla omthelela, nezinye izici.

Kwezinye izindawo, ukukhwabanisa kuyisixazululo esihle.Mayelana nalokhu, akekho ozokhiqiza ngokushesha imishayo yensimbi ye-I kusuka ku-powder metal noma ama-crowbars.Kodwa uma kuziwa ezingxenyeni ezincane ezinemiklamo eyinkimbinkimbi, i-powder metallurgy iye yadlula ukwakhiwa.Njengoba singena esikhathini esizayo sokukhiqizwa kwezingxenye (ezifana nezinjini zikagesi ekwakhiweni kwezimoto ezithuthukayo), i-powder metallurgy izodlala indima ebaluleke kakhulu.Uma izici ezifana nokuthengeka, ukukhiqizwa okuphezulu, kanye nengxube yensimbi iqala ukusebenza, i-PM ngokusobala iyikusasa.Nakuba ukuqamba kungahlinzeka ngezakhiwo ezinhle kakhulu zemishini, kufanele kukhokhe ukulahlekelwa kwezindleko ezinkulu uma kuqhathaniswa nensimbi yempushana evamile.Ngokusebenzisa izinto zanamuhla nezinqubo, izinsimbi zomdabu eziyimpuphu zinganikeza ukusebenza okudingekayo uhlelo lwakho lokusebenza ngezindleko ezincishiswe kakhulu.
