IZIXHOBO ZESIXESHA ZOPHUWU

Izinto zesinyithi esekwe ngumgubo wesinyithi

Izinto zesinyithi ezisekelwe kwi-iron-powder metallurgy zenziwa ikakhulu ngamacandelo esinyithi, kunye neklasi yentsimbi kunye nezixhobo zetsimbi ezenziwe ngokudibanisa izinto ezixubileyo ezifana ne-C, Cu, Ni, Mo, Cr, kunye ne-Mn. Iimveliso ezisekwe kwintsimbi lolona hlobo luvelisayo lwemathiriyeli kushishino lwesinyithi somgubo.

1. I-iron-based powder

Umgubo osetyenziswa kumgubo wesinyithi esekwe kwimathiriyeli kunye neemveliso ikakhulu zibandakanya umgubo wentsimbi ecocekileyo, umgubo wentsimbi esekwe kwisinyithi, umgubo owenziwe ngentsimbi wangaphambili, njl.

2. PM iimveliso ezisekelwe kwintsimbi

Itekhnoloji yesiqhelo yokucinezela/i-sintering inokuvelisa ngokubanzi iimveliso ezisekelwe kwintsimbi ezinobunzima be-6.4 ~ 7.2g/cm3, ezisetyenziswa kwiimoto, izithuthuthu, izixhobo zasekhaya, izixhobo zombane kunye namanye amashishini, kunye nezibonelelo zokufunxa ukothuka, ukunciphisa ingxolo, ubunzima obulula kunye nokonga amandla.

3. I-Powder injection molding (MIM) iimveliso zentsimbi

I-Metal powder injection molding molding (MIM) isebenzisa umgubo wesinyithi njengemathiriyeli ekrwada ukwenza iindawo ezincinci zetsimbi ezinemilo entsonkothileyo ngenkqubo yokubumba inaliti yeplastiki. Ngokubhekiselele kwizinto ze-MIM, i-70% yezinto ezisetyenziswayo ngoku ziyinsimbi engenasici kunye ne-20% zizinto zensimbi eziphantsi. Itekhnoloji ye-MIM isetyenziswa kakhulu kwiifowuni eziphathwayo, ikhompyuter kunye nezixhobo ezincedisayo, njengeefowuni ze-SIM kliphu, amakhonkco ekhamera, njl.

Ipowder metallurgy cemented carbide

I-carbide ene-cemented yi-powder metallurgy hard material kunye ne-transition group refractory metal carbide okanye i-carbonitride njengeyona nto iphambili. Ngenxa yamandla ayo amahle, ukuqina kunye nokuqina okuhambelanayo, i-carbide ene-cemented isetyenziswa ikakhulu njengezixhobo zokusika, izixhobo zemigodi, iindawo ezingagugiyo, izando eziphezulu, imiqulu, njl., kwaye isetyenziswa ngokubanzi kwintsimbi, iimoto, i-aerospace, izixhobo zomatshini we-CNC. , ishishini koomatshini Ukungunda, izixhobo zobunjineli zaselwandle, izixhobo zokuhamba kaloliwe, ishishini lobuchwepheshe bolwazi lwe-elektroniki, oomatshini bokwakha kunye nezinye izixhobo zokwenza kunye nokusebenza kunye nokwembiwa kwemigodi, i-oyile negesi yobutyebi ukukhutshwa, ukwakhiwa kweziseko ezingundoqo kunye namanye amashishini.

Izinto eziphathekayo zemagnethi yomgubo

Izixhobo zemagneti ezilungiselelwe ngokubumba umgubo kunye neendlela zokucoca zinokwahlulwa zibe ziindidi ezimbini: umgubo wesinyithi sesinyithi sezinto ezisisigxina zemagnethi kunye nemathiriyeli yemagnethi ethambileyo. Izixhobo zemagnethi ezisisigxina ikakhulu zibandakanya imathiriyeli yemagnethi ye-samarium cobalt enqabileyo yomhlaba esisigxina, i-neodymium, intsimbi, izixhobo zemagnethi esisigxina ye-boron, imathiriyeli yemagnethi esisigxina ye-AlNiCo, izixhobo zemagnethi ezisisigxina ze-ferrite, njl njl.

I-advanteji ye-powder metallurgy yokulungisa imathiriyeli yamagnetic kukuba inokulungisa amasuntswana omagnetic kuluhlu lobungakanani besizinda esinye, ifezekise ulungelelwaniso olungaguqukiyo lomgubo wemagnethi ngexesha lenkqubo yokucinezela, kwaye ivelise ngokuthe ngqo iimagnethi zemveliso yamandla kamagnethi kufutshane nemo yokugqibela, ngakumbi. kumatshini onzima kunye nemathiriyeli yemagnethi enqabileyo. Ngokubhekiselele kwizinto eziphathekayo, izibonelelo ze-powder metallurgy zivelele ngakumbi.

Iipowder metallurgy superalloys

I-powder metallurgy superalloys isekelwe kwi-nickel kwaye yongezwa kunye nezinto ezahlukeneyo zokuhlanganisa ezifana ne-Co, Cr, W, Mo, Al, Ti, Nb, Ta, njl. iipropati. I-alloy yimathiriyeli yezinto eziphambili zesiphelo esishushu ezifana neeshafti ze-injini ye-aero-injini, ii-baffles ze-iturbine disk, kunye neediski zomoya. Ukulungiswa kubandakanya ukulungiswa komgubo, ukubumba ukuhlanganiswa kwe-thermal, kunye nonyango lobushushu.

Iqela lethu lobuchwephesha liya kucebisa ngezinto ezisekelwe kwiipropati zakhoiinxalenye zentsimbi yomgubo. Uluhlu olukhulu lwezixhobo ezinokusetyenziswa ukwanelisa iimfuno zakho ngokwexabiso, ukuqina, ulawulo lomgangatho, kunye nezicelo ezithile yenye yeenzuzo eziphambili zokusebenzisa umgubo wesinyithi ukuvelisa amacandelo. Intsimbi, isinyithi, i-tin, i-nickel, ubhedu, i-aluminiyam, kunye ne-titanium ziphakathi kweentsimbi ezisetyenziswa rhoqo. Kunokwenzeka ukusebenzisa isinyithi esichasayo kuquka ubhedu, ubhedu, insimbi engenasici, kunye ne-nickel-cobalt alloys, kunye ne-tungsten, i-molybdenum, kunye ne-tantalum.

Ukucinezela

Ifakwe kwi-hydraulic okanye i-mechanical press ethe nkqo apho ifakwe kwisixhobo sentsimbi okanye i-carbide die xa i-alloy efanelekileyo yomgubo ixutywe. UJIEHUANG unokucinezela amacandelo ukuya kuthi ga kumanqanaba amane ahlukeneyo eenkcukacha ezilungileyo. Ngokuxhomekeke kubungakanani kunye neemfuno zoxinaniso, le ndlela isebenzisa uxinzelelo lwe-15-600MPa ukuvelisa iindawo "eziluhlaza" ezinazo zonke iimpawu zejometri ezifunekayo zoyilo lokugqibela. Nangona kunjalo, akukho nxalenye yemilinganiselo yokugqibela okanye iimpawu zayo zomatshini ezikhoyo ngeli xesha. Unyango olulandelayo lobushushu, okanye "sintering," inyathelo ligqibezela ezo mpawu.

Isinyithi sintering (inkqubo sintering kumgubo metallurgy)

Iziqwenga eziluhlaza zondliwa kwisithando somlilo de zifikelele kumandla afunekayo okugqibela, ukuxinana, kunye nokuzinza komda. Kwinkqubo ye-sintering, amaqondo okushisa angaphantsi kwendawo yokunyibilika yecandelo eliphambili lepowder inxalenye lifudumala kwindawo ekhuselweyo ukuze i-molecularly idibanise i-particle powder particles eyenza inxalenye.

Ubungakanani kunye namandla amanqaku oqhagamshelwano phakathi kweengqungquthela ezixinzelelweyo zikhula ukuphucula iimpawu zobugcisa becandelo. Ukuze kuhlangatyezwane neeparamitha zecandelo lokugqibela, i-sintering inokuncipha, yandise, iphucule i-conductivity, kunye/okanye yenze inxalenye yomelele ngokuxhomekeke kuyilo lwenkqubo. Kwiziko elitshisayo, amacandelo afakwa kwi-conveyor eqhubekayo kwaye ngokucothayo ahanjiswe kumagumbi eziko ukuze afeze imisebenzi emithathu ephambili.

Ukuphelisa ii-lubricants ezingafunekiyo ezifakwe kwi powder ngexesha lenkqubo yokudibanisa, iziqwenga ziqala ukufudumeza ngokukhawuleza. Amacandelo alandelayo aqhubela phambili kwindawo yokushisa ephezulu yesithando somlilo, apho iimpawu zokugqibela zamacandelo zinqunywe kumaqondo okushisa alawulwa ngokuchanekileyo ukusuka kwi-1450 ° ukuya kwi-2400 °. Ngokulungelelanisa ngononophelo umoya ongaphakathi kweli gumbi lomlilo, iigesi ezithile zongezwa ukunciphisa iioksidi ezikhoyo kunye nokumisa i-oxidation eyongezelelweyo yamalungu ngeli nqanaba lobushushu obuphezulu. Ukugqiba iziqwenga okanye uzilungiselele naziphi na iinkqubo ezongezelelweyo, ekugqibeleni zihamba ngegumbi lokupholisa. Ngokuxhomekeke kwizinto ezisetyenzisiweyo kunye nobukhulu bamacandelo, umjikelezo wonke unokuthatha imizuzu engama-45 ukuya kwiiyure ze-1.5.

Emva kokulungiswa

Ngokubanzi, iiimveliso sinteringinokusetyenziswa ngokuthe ngqo. Nangona kunjalo, kwezinye iimveliso zetsimbi zensimbi ezifuna ukuchaneka okuphezulu kunye nobunzima obuphezulu kunye nokumelana nokunxiba, unyango lwe-post-sintering luyafuneka. I-post-processing ibandakanya ukucofa okuchanekileyo, ukuqengqeleka, ukukhupha, ukucima, ukucima umphezulu, ukucwiliswa kweoli, kunye nokungena ngaphakathi.

Inkqubo yonyango yobuso bomgubo wesinyithi
