The Special Alloys Context
Sei kunyange kushandisa Alloy 1 paunenge uine cobalt-based kana nickel-based superalloys? Ndiyo yekare 'fit-for-purpose' nharo. Ndakabatanidzwa muchirongwa chekugadzira makemikari skid. Chekutanga chemutengi chaidaidza nickel alloy yenhengo dzese dzakanyorova nekuda kwe'corrosion resistance.' Mushure mekuongorora iyo chaiyo makemikari media - yakapfava organic solvent pane ambient tembiricha - takakurudzira giredhi rakafambiswa zvakanaka Alloy 1 (a 316L musiyano, mune iyo kesi). Mari yekuchengetedza yaive pamusoro pe60%, kwete muzvinhu chete, asi munguva yekugadzira. Chikamu chave chiri mubasa kwemakore manomwe zvino pasina nyaya. Iwo masikirwo ekuwedzera-kutsanangura akasimba, kunyanya mumaindasitiri ane hurongwa, asi ruzivo runokudzidzisa kusunda kumashure nedata uye dzimwe mhinduro.
Izvo zvakati, kushanda nemaexotic alloys kunokupa kukoshesa kwakadzama kwehwindo rekugadzirisa re Alloy 1. Nickel alloys ane viscous kana akakandwa, cobalt alloys yakaoma kuita muchina. Alloy 1 ndiko, nokuenzanisa, kukanganwira. Asi 'kukanganwira' hazvirevi 'kureruka.' Zvinoreva kuti muganho wekukanganisa wakawedzera, asi zvikanganiso zvichiri kuitika kana usina hanya. Ndiwo musiyano pakati pekutyaira mumugwagwa wakapamhama uye mugomo wakamanikana; uchiri kuda kuterera.
PaQSY, chokwadi chekuti vanobata magumo ese echiratidziro-kubva kune akajairwa alloys kune akakosha-inobatsira chaizvo. Zvinoreva nzira yekuronga basa mukati Alloy 1 inoziviswa nechirango chakanyanya chinodiwa kune superalloys. Iyo yakaoma inodzika pasi.

Aya aiita seanoisa kushushikana panguva yekukurumidza kupisa uye kudzimwa kwekuomesa induction. Izvo zvinhu zvakasangana neyakajairwa kemikari yekuumbwa kwemhando pane cert, asi yaive pamucheto weiyo renji yesarufa. Chidzidzo chacho? Kune dzakakomba, post-machining kupisa-yakagadziriswa zvikamu, iwe unofanirwa kuomesa iyo yezvinyorwa kupfuura iyo yakajairwa ASTM renji uye tsanangura kusanganisa kutonga. Iwe unobhadhara yakawanda yekunyungudika, asi iwe unochengetedza mari yakawanda mukunzvenga kutadza kwemunda.
Imwe yakajairika, inenge yakapusa, yekutadza maitiro ndeye galvanic corrosion. Bolting an Alloy 1 (toti, carbon steel) flange kune pombi yesimbi isina simbi isina simbi. Izvo zvakakosha, asi mumagungano akaoma ane akawanda zvinhu, zvinoregeredzwa. The Alloy 1 chikamu chinova chibayiro anode uye corrodes kure. Hakusi kukundikana kwezvinhu; idhizaini uye gungano rekutarisa. Iwe unoona zvikamu izvi zvichidzoka kuti 'zvipfeke nguva isati yakwana,' uye kugadzirisa i $ 0.50 insulating gasket.
Kukundikana uku ndiko kuvaka ruzivo rwemasangano mukambani. Ndosaka chitoro chine makore makumi matatu enhoroondo, senge iri kumashure tsngtaocnc.com, ine kukosha kupfuura rondedzero yayo yemuchina. Vanogona kunge vakasangana uye vakagadzirisa aya chaiwo, matambudziko akashata.
Kupedzisa Pasina Mhedziso
Saka, izvo zvinotisiya papi Alloy 1? Haisi nyaya yaunogona kupedzisa zvakanaka. Chinhu chinotsanangurwa nekugadzirisa kwayo. Kuita kwayo kubatana pakati pemetallurgist, muvambi injiniya, CNC programmer, uye anopisa kupisa. Iwe haugone kungotenga 'Alloy 1' uye kutarisira mhedzisiro. Iwe unofanirwa kuitsanangura, kuiumba, kuicheka, uye kuibata nechinangwa chaicho mupfungwa.
Hunyanzvi chaihwo huri pakuziva kuti ndeapi marevhisi ekudhonza kuti ashandise application ipi. Inoda anneal yakajairwa here kana kudzima uye kushatirwa? Inofanira kuve yakaoma muchina isati yabatwa kupisa uye wozopedzisa kugadziridzwa, kana iwe unogona kuigadzira yese iri munzvimbo yakavharwa? Hapana mhinduro imwe chete. Iwo mapepa edata anokupa pekutangira, asi yekupedzisira maitiro ekubika inonyorwa kuburikidza nekuyedza, kukanganisa, uye nekutarisa pachitoro pasi.
Pakupedzisira, Alloy 1 chiratidzo chepfungwa yekuti mukugadzira, hapana zvinhu zvinofinha, asi maitiro asina kunyatsonzwisiswa. Inoda ruremekedzo kwete nekuda kwechimiro chayo chekunze, asi nekuda kwekuzara kwayo uye hunyengeri hwekusiyana kwayo. Kuiwana nguva dzose zvakanaka, batch after batch, gore negore, ndizvo zvinoparadzanisa chitoro chebasa kubva kune wechokwadi wekugadzira mudiwa. Ndiro basa risina kunaka, zuva nezuva rinoita kuti indasitiri irambe ichishanduka.
