Iyini inzuzo ye-MIM ne-PM

Ukubumba umjovo wensimbi

1.Ubuchwepheshe bokubumba umjovo wensimbiingakwazi ukukhiqiza izingxenye ezincane ngokunemba okuphezulu, Ukuthanda ukukhiqizwa kwemikhiqizo yepulasitiki yokukhiqiza ijamo elincane elincaneizingxenye zensimbi zensimbi(usayizi ngokuvamile 0.1-100g);

2. izingxenye zokugxiviza zihlela umfaniswano, ukuminyana, ukuminyana okuhlobene okungama-95% - 99%, ukwelashwa kwe-carburizing, ukucisha kanye nokushisa okushisa kungenziwa, ukunemba okuphezulu kwe-dimensional kanye nokucutshungulwa kwemishini kungase kusetshenziselwe ukucutshungulwa;

Inqubo yokubumba ye-3.metal injection ingakhiwa ngesikhathi esisodwa usayizi womkhiqizo wensimbi/izingxenye ze-auto ukunemba kungaba kufika ku-+ / – 0.1 ~ 0.5%, indawo engaphezulu ikhanya futhi ihlanzekile, kanye kanye ukuya ku-Ra1.6;

4.Ubuchwepheshe bokubumba umjovo wensimbiizingxenye zensimbi zezingxenye zezimoto ezinokuzinza kwekhwalithi yomkhiqizo, ukusebenza kahle kokukhiqiza okuphezulu, esimweni sokukhiqizwa kwenani elikhulu lezimpahla, futhi izindleko zingancishiswa kakhulu.

I-powder metallurgy

1. Izinsimbi eziningi eziphikisayo nezinhlanganisela zazo, ama-pseudo-alloys nezinto ezimbotshana zingenziwa kuphela nge-powder metallurgy.

2, ngoba indlela yokucindezela i-powder metallurgy ingacindezelwa kusayizi wokugcina we-billet, ngaphandle noma kancane isidingo sokucutshungulwa komshini okulandelayo, ingasindisa kakhulu insimbi, yehlise izindleko zomkhiqizo.Laphoimikhiqizo eyenziwe nge-powder metallurgy, ukulahlekelwa kwensimbi kungu-1-5% kuphela, kuyilapho kungase kube phezulu njenge-80% uma kukhiqizwa ngezindlela ezijwayelekile zokuphonsa.

3. Njengoba inqubo ye-metallurgy ye-powder ingancibiliki izinto ezibonakalayo ekukhiqizeni izinto ezibonakalayo, akesabi ukuxuba ukungcola okulethwe yi-crucible kanye ne-deoxidizer, njll., kuyilapho i-sintering ngokuvamile iqhutshwa ku-vacuum nokunciphisa umkhathi, ngaphandle kokwesaba i-oxidation futhi ngaphandle kokungcoliswa kwezinto ezibonakalayo, ngakho-ke kungenzeka ukukhiqiza izinto ezihlanzekile.

4. I-powder metallurgy ingaqinisekisa ukunemba nokufana kwesilinganiso sokwakheka kwezinto.

5.inqubo yensimbi eyimpuphukufanelekile ukukhiqizwa kwesimo esifanayo nenani elikhulu lemikhiqizo, ikakhulukazii-powder metal gearnezinye izindleko eziphezulu zokucubungula imikhiqizo,ukwenziwa kwe-powder metallurgyzinganciphisa kakhulu izindleko zokukhiqiza.
