Incamake: Imfashanyigisho ya tekinike kuri Inconel 718 ibibazo byo gushora imari, harimo guturika no gutunganya, hamwe nibyo abaguzi bagomba kugenzura mubitanga.
Inconel 718 nimwe mubikoreshwa cyane na nikel ishingiye kuri superalloys. Ikomeza imbaraga nyinshi, irwanya kunyerera, nubuzima bwumunaniro mubushyuhe bugera kuri 700 ° C.
Iyi mitungo ituma ihitamo risanzwe ryibikoresho bya moteri yindege, turbine, nibikoresho bya peteroli na gaze.
Nyamara, ibintu bimwe bituma Inconel 718 yifuzwa nabyo bituma bizwi ko bigoye gukina no gukora imashini.
Iyo biva Inconel 718 gushora imari ibice, abaguzi akenshi basanga atari buri ruganda rushobora gutanga amajwi.
Gusobanukirwa imizi ya metallurgiki yizi ngorane ni ingirakamaro kuruta gusaba urutonde rwimpamyabumenyi.
Impamyabumenyi yerekana ko ikigo cyatsinze igenzura, ntabwo bivuze ko kugenzura imikorere yacyo bishobora gucunga iyi mavuta yihariye.
Impamvu Inconel 718 itoroshye mugushora imari
Gutera ishoramari bikwiranye na Inconel 718 kuko ishobora kubyara imiterere igoye, hafi-net kandi ikagabanya umubare wa superalloy ihenze yakuweho no gukora.
Ariko inzira yo gukomera irangwa no gukina itangiza ibyago bibiri byibanze.
Ingaruka zo Gucika Ashyushye (Icyiciro cya Lave)
Inconel 718 irimo niobium (Nb). Mugihe cyanyuma cyo gukomera, amazi asigaye aba akungahaye muri Nb, silicon, nibindi bintu, bigatera ishingwa ryicyiciro cya Laves.
Ubushakashatsi bwerekana ko n'urwego rwa Laves rusigaye urwego ruri munsi ya 0.14–0.35 wt% rushobora kubangamira ihindagurika rishyushye hamwe nuburyo bwo guturika.
Kubaho kwicyiciro cya Laves byagura uburyo bwiza bwo gukonjesha, hasigara uturere twa interdendritic udafite ihindagurika rihagije kugirango ryemere imitsi yo kugabanuka bitinze gukomera.
Mugihe cyimiterere yubushyuhe, ibi biganisha kumarira.
Igipimo cyo gukonjesha nicyo gihinduka cyibanze cyo kugenzura icyiciro cya Laves. Gukonja gahoro gahoro bituma niobium itandukana kandi ikongerera amahirwe yo kugumana icyiciro cya Laves gisigaye mubushyuhe bwicyumba; gukonjesha byihuse birashobora guhagarika igice.
Kubwibyo, ubushobozi bwumushinga wo kugenzura ubushyuhe bwubushyuhe, gusuka ubushyuhe, hamwe na gahunda yo gukonjesha byerekana neza intsinzi yayo mukurinda ibice bishyushye.
Kugabanuka no Kwishisha Imbere
Imyitwarire yo kugabanuka ya Inconel 718 irumva cyane idirishya ryibikorwa. Ubushakashatsi bwikigereranyo kuri turbine blade bwerekana ko iyo igihe cyo gutura cyiyongereye kuva kuri 0 kugeza kuri 420 s, ubushyuhe bwibishishwa bugabanuka kuva kuri 1000 ° C kugeza kuri 860 ° C, kandi kugabanuka kwinshi hamwe ninshuro byiyongera bikwiranye.
Ibi bivuze ko niba imicungire yubushyuhe mbere yo gusuka itandukanijwe nidirishya ryabugenewe, imbere imbere biziyongera cyane.
Imbere yimbere muri Inconel 718 casting ntabwo ari ibintu bidasanzwe ahubwo ni uburyo busanzwe bwo gutsindwa biturutse kugenzura bidahagije.
Kubintu bitwara imitwaro cyangwa umunaniro-bikomeye, nubwo nyuma yo gukanda Isostatike ishyushye (HIP), kugabanuka kwa micro birashobora kugabanya ubuzima bwumunaniro.
Kubwibyo, kugabanuka kugabanuka bigomba gukemurwa uhereye kumiterere ya sisitemu yo gutangiza no kwigana ibyiciro.
Ibibazo nyuma yo gukina: Gukora Inconel 718
Ndetse amajwi aracyerekana ibibazo bikomeye byo gutunganya. Inconel 718 ifite ubushyuhe buke bwumuriro, yibanda ku kugabanya ubushyuhe hafi yigikoresho, mugihe imiterere ya austenitike itera imirimo yihuse gukomera mugihe cyo guhagarika umutima.
Iyi mirimo ikomantaye yihutisha kwambara kumpande, ikora uruziga aho gukata bituma ibikoresho bigorana, nabyo bikambara igikoresho vuba.
Mugukata ibipimo, ibikoresho bya karbide bidafunze bikora neza murwego rwa 10-30 m / min; kumuvuduko uri hejuru ya 40 m / min, gushyiramo karbide yinjizwamo birakwiye.
Uru rutonde rwihuta ruri munsi yibipimo bisanzwe bya aluminium cyangwa ibyuma bisanzwe, bivuze ko igihe cyo gutunganya nigiciro cyibikoresho bya Inconel 718 kiri hejuru cyane.
Urebye amasoko, ibi bizamura ingingo yo gusuzuma isoko: ibishingwe bifite ubushobozi bwo gutunganya inzu mubisanzwe ufite akarusho kurenza abaterankunga gusa.
Imyitwarire ya Inconel 718 isaba guhuza ibikorwa byo kugabanya ibipimo, inzira y'ibikoresho, hamwe no gukomera.
Niba uruganda rugenzura kwihanganira guterana hamwe n’amafaranga yo gutunganya, birashobora kwerekana uburyo bukwiye mugihe cyo gukina, bikagabanya ibyago byo kwambara ibikoresho bidasanzwe cyangwa kwangirika kwubuso bwatewe nubufasha budakwiye.
Nigute wasuzuma Inconel 718 Yashinzwe
Iyo usuzumye abatanga isoko ya Inconel 718, ibyemezo ni ntarengwa, ntabwo ari ibintu bihagije.
Ubushobozi bukurikira burerekana cyane niba koko ikigo kigenzura iyi mavuta.
1. Gushonga no Gusuka Kugenzura Ikirere. Inconel 718 yunvikana kuri ogisijeni, azote, na hydrogen, bisaba kurindwa bikwiye mugihe cyo gushonga no gusuka.
Gushonga Vacuum Induction (VIM) birashobora kugabanya okiside na gaze ya gaze aho bibaye ngombwa, ariko ntabwo Inconel 718 yose ikenera VIM. Inzira yinzira igomba kwemezwa kubice bisobanutse hamwe nibisabwa.
2. Kugenzura Ubushyuhe. Gukomera kwa Inconel 718 ntabwo byerekana imikorere ya serivisi ya nyuma.
Inzira isanzwe itunganya ubushyuhe mubuvanganzo bwinganda igizwe no kuvura ibisubizo bigera kuri 980 ° C bikurikirwa no gukonja byihuse, gusaza bwa mbere kuri 720 ° C kumasaha 8, gukonjesha itanura kugeza kuri 620 ° C kumusaza wa kabiri wamasaha 8, no gukonjesha ikirere.
Ibi byiciro bibiri gusaza bigusha γ ″ gukomera icyiciro gishinzwe imbaraga za alloy.
Niba utanga isoko adafite itanura ryagenzuwe hamwe nubushyuhe bwo gukurikiranwa, ubushyuhe bushobora kuba bwujuje ubuziranenge bwibyuma ariko bikananirana nubutunzi bwibikoresho.
3. Ibipimo byo Kwipimisha bidasenya (NDT). Kugabanuka kwimbere hamwe nubushyuhe bwo gushyuha bwa Inconel 718 bivuze ko NDT idashobora kwishingikiriza kugenzura wenyine.
Imirasire ya X-yerekana igabanuka ryimbere nigisenyuka, igenzura rya fluorescent penetrant (FPI) ryerekana inenge zimeneka hejuru, kandi kwipimisha ultrasonic birashobora kuzuza hafi yubuso cyangwa isuzuma ryimbere.
Emeza niba NDT ikorerwa murugo cyangwa hanze, kandi niba ibipimo byo kwemera bihuye nibisabwa igice.
4. Gukurikirana ibikoresho no guhuza ibice. Ibigize imiti ya buri Ubushyuhe bwa Inconel 718 - cyane cyane urwego rwa Nb, Si, na C - kandi amateka yayo akonje bigira ingaruka kumiterere ya Laves.
Gusaba ubushyuhe-nimero-yo gushonga inyandiko, ibiti byo kuvura ubushyuhe, na raporo ya NDT nuburyo butaziguye bwo gusuzuma niba kugenzura ibikorwa byabatanga ibintu biri kuri gahunda.
5. Gutera-Kumashini Kwishyira hamwe. Nkuko byavuzwe, Inconel 718 akazi gakomeye bituma intera iri hagati yo gukina no gutunganya ari ngombwa.
Niba utanga isoko ashobora gucunga ibikorwa byose murugo, guhuza itangwa ryokwihanganirana, igishushanyo mbonera, hamwe ningamba zo gukosora inenge mubisanzwe birakorwa neza.
Kurugero rwubushobozi bwo gutunganya ibintu bigoye, urashobora gusuzuma ubushobozi bwacu.
Gusaba-Ibitekerezo byihariye
Inconel 718 gushora imari mubisanzwe biri mubyiciro bibiri byo gusaba.
Moteri yo mu kirere hamwe na gaz turbine ibice bishyushye byubaka (nka casings, gushiraho flanges, hamwe na brake) bisaba imikorere yumunaniro mwinshi, hamwe no kwihanganira bike kubibazo byimbere hamwe nibibazo byubusugire.
Ibikoresho bya peteroli, gaze, ningufu ibice nkimibiri ya valve, ibice bya pompe, nibice bya wellhead byibanda cyane kubirwanya ruswa hamwe nubusugire bwumuvuduko, aho idirishya ryihanganira inenge kubice-bishyushye-bitoroshye ariko ibice bidafite umunaniro birashobora kuba binini cyane.
Ibi ntibisobanura ko porogaramu imwe "yoroshye" guta. Bivuze ko abatanga isoko bashimangira bagomba guhinduka hamwe nimikoreshereze yanyuma.
Uruganda rufite inyandiko ihamye yo gutanga ibintu ku buryo budasanzwe bwo gutondeka ibintu ntibishobora kuba bifite uburyo bwo kugenzura no gukoresha ibyangombwa bisabwa mu kirere cyo mu kirere Inconel 718.
Gutomora igice cyanyuma gisabwa hamwe nibisabwa mugihe cyicyiciro cya RFQ bifasha uwabitanze kumenya niba ubushobozi bwibikorwa byacyo bihuye, wirinda kuvumbura ibipimo byemerwa bidahuye gusa havutse ikibazo cyiza.
