Powder metallurgy vs simintin gyaran kafa

1. Kayan danye

Yin wasan kwaikwayo– Kayayyakin simintin gyare-gyare galibi ba kayan ƙarfe ba ne, kamaraluminum, magnesium, zinc, wanda ke da ƙananan abubuwan narkewa. Siffar samfurin simintin zai iya zama faranti, bel, sanda, da dai sauransu;

Foda karfe– Ƙarfe ko ƙarfe (ko cakuda foda da foda mara ƙarfe) a matsayin kayan albarkatun kasa. Ko da yake akwai ma'aunifoda karfe kayan, Hakanan yana yiwuwa a haɗa foda. Wannan yana ba da damar ƙirƙirar ƙayyadaddun ƙayyadaddun ƙayyadaddun kaddarorin, irin su manyan kaddarorin maganadisu na abubuwan motsa jiki, waɗanda ke buƙatar babban ƙarfe mai narkewa. Ƙarfe na foda yawanci ya ƙunshi abubuwa masu zuwa:Bakin karfe, baƙin ƙarfe, nickel, titanium, jan karfe, silicon, phosphorus.

2. Tsari

Yin wasan kwaikwayo- shine amfani da kayan daga ruwa zuwa gyare-gyaren lokaci mai ƙarfi, ƙarfe ya narke gaba ɗaya, tsarin samfurin ƙarshe ya canza.

Powder Metallurgy- shine fasahar tsari na yin ƙarfe ko foda na ƙarfe (ko cakuda foda na ƙarfe da foda mara ƙarfe) azaman kayan albarkatun ƙasa, ƙirƙira da sintiri, kera kayan ƙarfe, haɗaka da nau'ikan samfura daban-daban.

3. Maganin zafi

Yin wasan kwaikwayo- Dangane da kayan aiki daban-daban da bukatun aiki na iya samun matakai daban-daban na maganin zafi, irin su aluminum alloy annealing, quenching, maganin bayani, ƙarfafa tsufa;

Foda karfe– na al'ada foda metallurgy hanya, da abu ba zai iya zama gaba daya m, babu makawa samar da wasu gibba, zai rage da ƙarfi, bisa ga daban-daban bukatun na kayan Properties, ƙayyade ko zafi magani bayan sintering, kullum ta hanyar quenching da tempering iya inganta yi na kayan.

 4. Kula da kungiya

Yin wasan kwaikwayo– Inmutu simintin, An ƙaddara ikon sarrafa ƙananan ƙwayoyin cuta ta hanyar kwantar da hankali, wanda ya dogara da dalilai kamar yanki da girma, kuma ƙungiyar simintin ya fi girma.

Foda karfe- Foda saboda albarkatun kasa yana da ƙananan ƙananan, ta hanyar sarrafa tsari, zai iya samun hatsi iri ɗaya, ƙananan microstructure, gaba ɗaya kauce wa abun da ke ciki da kuma rarrabuwar microstructure da aka samar ta hanyar jefawa. Kowace zagayowar tana ajiye nau'in nau'in foda a cikin ƙirar kuma tana haɗa shi zuwa yawa iri ɗaya. Foda karafa kayan ne zafi isostatic matsi, da yawa na talakawa sintered kayan ba shi da kyau a matsayin simintin gyaran kafa.

5. Mechanical Properties

Idan aka kwatanta da wasu matakai,mutu simintinyana ba da damar gyare-gyare masu kyau sosai. Koyaya, zamu iya amfani da kusan damar ƙira iri ɗaya azaman samfuran ƙarfe na foda don ba samfuran ingantattun kaddarorin inji.

Kayayyakin simintin gyare-gyare ba magnetic ba. Sai dai idan an saita su a cikin wani ɓangaren da aka yi da wani ƙarfe, babu dacewa da maganadisu. Ƙarfe na foda yana da nau'ikan kayan maganadisu da ake samu. Wata matsala tare da mutuwar simintin gyare-gyare ita ce samfurin yana da rauni kuma cikin sauƙin karyewa. Babban kayan sassa na simintin simintin gyare-gyare sune zinc da aluminum, waɗanda ke da ƙarancin ƙarfe mai laushi.Foda karfe sassa, yawanci da karfe, suna da taurin mafi girma. Yin amfani da kayan aiki masu ƙarfi zai iya cimma siffar guda ɗaya tare da ƙananan kayan aiki, wanda zai iya ajiye sararin ƙirar mota da nauyi.

6. Farashin

Ƙirar ɓangarori shine babban direban farashi, kodayake ƙira za a iya keɓance shi don dacewa da tsarin gyare-gyare. Koyaya, akwai bambance-bambance tsakanin samfuran ƙarfe na foda da simintin simintin gyare-gyare, kuma waɗannan bambance-bambancen su ne manyan abubuwan da ke shafar farashin.

Amfani da kayan aiki/samuwar. Kayayyakin karafa na foda suna da ƙarancin tarkace, wanda shine babban fa'ida a cikin amfani da kayan ƙima kamar jan ƙarfe da bakin karfe.

Yin aiki na sakandare. Ana buƙatar gyara sassan simintin da aka mutu don cire ɗanyen gefuna, sake gyarawa da kuma kula da zafi; Yawancin sassan ƙarfe na foda ba sa buƙatar sarrafa na biyu.

Amfanin danyen abu. Ƙarfe na narkewa yana da ƙarfin kuzari, musamman ga kayan da ke da maki mafi girma. Kodayake sintering shima yana da ƙarfin kuzari, jimillar amfani da sintering na iya zama ƙasa da na simintin.
