Yintoni inzuzo ye-MIM kunye ne-PM

Isitofu sesinyithi sokubumba

1.Itekhnoloji yokubumba inaliti yesinyithiinokuvelisa iindawo ezincinci ngokuchaneka okuphezulu,Ukuthanda ukuveliswa kweemveliso zeplastiki imilo entsonkothileyo encinciiinxalenye auto metal(ubungakanani ngokuqhelekileyo ngu-0.1-100g);

2. iindawo zokunyathela ziququzelela iyunifomu, ukuxinana, ukuxinana kwe-95% - 99%, ukungcwatywa kwe-carburizing, ukucima kunye nokushisa ukushisa kunokwenziwa, ukuchaneka okuphezulu okuphezulu kunye nokulungiswa koomatshini kungasetyenziselwa ukusetyenzwa kwangemva;

Inkqubo yokubumba i-3.metal ye-metal inokwenziwa ngexesha elinye isinyithi / i-auto parts yesayizi yemveliso echanekileyo ingafikelela ku- + / - 0.1 ~ 0.5%, umphezulu ukhanya kwaye ucocekile, ixesha elilodwa ukuya kwi-Ra1.6;

4.Itekhnoloji yokubumba inaliti yesinyithikwiindawo zentsimbi zeauto ezinozinzo lwekhwalithi yemveliso, ukusebenza kakuhle kwemveliso, kwimeko yomlinganiselo wemveliso yobuninzi, kwaye iindleko zinokuncitshiswa kakhulu.

Metal naliti ukubumba iindawo

I-metallurgy yomgubo

1. Uninzi lwesinyithi esichasayo kunye neekhompawundi zazo, i-pseudo-alloys kunye nezixhobo ezixhamlayo zingenziwa kuphela nge-powder metallurgy.

I-2, ngenxa yokuba i-powder metallurgy icinezela indlela yokucofa ingacinezelwa kubungakanani bokugqibela be-billet, ngaphandle okanye imfuneko encinci yokucutshungulwa komatshini olandelayo, inokugcina kakhulu isinyithi, inciphise iindleko zemveliso.Xaiimveliso ezenziwe ngomgubo wesinyithi, ilahleko yesinyithi i-1-5% kuphela, kanti ingaba phezulu njenge-80% xa iveliswa ngeendlela eziqhelekileyo zokuphosa.

3. Njengoko inkqubo ye-metallurgy ye-powder ayinyibiliki izinto eziphathekayo kwinkqubo yokuvelisa izinto, ayikoyiki ukuxuba ukungcola okulethwe yi-crucible kunye ne-deoxidizer, njl., ngelixa i-sintering iqhutyelwa ngokubanzi kwi-vacuum kunye nokunciphisa umoya, ngaphandle kokwesaba i-oxidation kwaye ngaphandle kokungcoliswa kwezinto eziphathekayo, ngoko kunokwenzeka ukuvelisa izinto ezicocekileyo.

4. I-metallurgy ye-powder inokuqinisekisa ukuchaneka kunye nokufana komlinganiselo wokubunjwa kwezinto.

5.inkqubo yesinyithi engumguboifanelekile kwimveliso yesimo esifanayo kunye nenani elikhulu leemveliso, ngakumbiizixhobo zentsimbi yomgubokunye nezinye iindleko eziphezulu zokulungisa iimveliso,ukwenziwa komgubo wesinyithiinokunciphisa kakhulu iindleko zemveliso.

ukwenziwa kwezixhobo zesinyithi somgubo
