Kana mumwe munhu akati 'incoloy part', vazhinji vanofunga kuti vari kungotaura nezve high-nickel alloy inodzivisa kupisa. Ndizvo zviri pamusoro. Chokwadi ndechekuti kuzvipira. Hausi kungohodha chikamu; uri kusaina kune yese process cheni uko ruzivo rwezvinhu chikamu chiri nyore. Chinetso chaicho chiri mukugadzira—kukanda, kugadzira, kutamba kwokurapa kunopisa. Ndakaona magadzirirwo akawandisa achikundikana nekuti vakabata Incoloy 825 kana 925 sesimbi isina tsvina. Hazvisizvo. Chikara chinoda ruremekedzo kubva pamaitiro ekutanga chaiwo.
Iyo Foundry Floor Reality
Ngatitangei painotangira: kudira. Neaya alloys, kunyanya epamusoro echromium akadai Ikoloy 800H, iyo shell mold process ishoma nezve art uye zvimwe nezve hutsinye hutongi. Gating dhizaini haisi yekuyerera chete; ndeyekusimba kwegwara kuti kuderedze kubvaruka kunopisa. Takadzidza izvi nenzira yakaoma pane batch yemiviri yevharuvhu makore kumashure. Zvikamu zvacho zvaitaridzika zvakanaka, asi kuyedzwa kwekumanikidza kwakaratidza madiki madiki padivi pechikamu chinoita sechisina kurongeka. Mupari wemhosva? Kutonhodza mwero kusaenderana muchikamu chakakora. Kusiyana kwekushisa kwe mold kwaingova 30 ° C kubva kune rimwe divi re autoclave kune rimwe. Ndizvo chete zvazvaida.
Apa ndipo panoratidzwa dzinza remuwaniredzi. Chitoro chinowanzo tengesa simbi chinonetsa. The thermal profiles inyika dzakaparadzana. Ndinoyeuka ndichishanya Qingdao Qiangsenyuan Technology (QSY) chinguva kumashure. Chakanga chakamira chaive chisiri kugona kwavo kwechoto, asi magwaro avo ezvinyorwa zvenickel-based alloys. Vaive nemazitanho chaiwo edova akarongerwa magadzirirwo avo ekuomesa magoko. Iyo nhanho yeruzivo inokuudza kuti vakarwa hondo yekunyorova-uye-gasi-porosity kare. Nguva yavo yemakore makumi matatu mukukandira haisi nhamba chete; iraibhurari yezvinetso zvakagadziriswa.
Post-cast heat treatment ndiyo imwe minefield. Solution annealing zvikamu izvi haisi 'kuiisa uye kuikanganwa' kutenderera kwevira. Iyo nguva mukati meiyo yakakosha tembiricha renji yekunaya kwecarbide yakasimba kwazvo. Kunyanya kunonoka kukwidza, uye iwe unowana sigma chikamu mumiganho yezviyo, uchiuraya kuoma. Isu takambofanira kurasa dzimba zhinji dzepombi nekuti choto chaive nechakaipa chethermocouple, ichimhanya 25°C inotonhorera pane yakaratidzwa. Zvikamu zvacho zvakapfuura madimensional cheki asi zvakapwanyika nekushushikana. Chidzidzo chacho? Zvitupa zvakanaka, asi mu-process kusimbiswa ndizvo zvese.
Machining: Papi Dzidziso Inosangana Nechokushandisa
Kana kukanda kuri kupisa kunodzorwa, machining Incoloy ihondo yekurwisa. Mwero wekuomesera basa unotyisa. Iwe unopinda neinopinza zvishoma, uye panguva yaunenge wave 2mm mukati mekucheka, zvinhu zvakawoma pamberi pechishandiso, zvichitungamira kumucheto chipping uye kupera kwakashata kwepamusoro. Hazvisi zvesimba remabhiza; ndezvekuoma uye kusagadzikana kusingagumi.
CNC programming yezvikamu izvi inoda huzivi hwakasiyana. Iwe haugone kushandisa nzira dzakafanana dzekumhanya, dzakareruka-pasi dzaungashandisa aluminium. Ndezvekumhanya kwakaderera, kudya kwakakwira, uye kugara uchibatikana kuti upinde pasi pebasa-rakaomeswa layer. Inotonhodza haisi yekutonhodza chete; iyo lubricant kudzivirira kuvakwa-kumucheto. Ndave nemhedzisiro yakanaka ne-high-pressure kuburikidza-tool inotonhorera, chaizvo kutyora chip nekuigeza isati yave mawelds. Shamwari yakadai QSY, nemitsara yavo yakatsaurirwa yeCNC yearoyi akakosha, kazhinji ine zvivakwa izvi. Vanonzwisisa kuti machining an Inoloy chikamu harisi basa repadivi redhipatimendi ravo risina tsvina.
Sarudzo yemidziyo iri pachena-ceramic kana carbide ine machira chaiwo. Asi iyo isinganyanyi kutaurwa-nezve gamba ndeye fixture. Iwe unoda misa uye clamping mapoinzi ayo asingagadziri harmonic vibration. Chero kutaura kwese kunobva kwashanda-inoomesa pamusoro, ichiparadza iyo inotevera kupfuura. Takambopedza mazuva maviri tichiedza kufunga kuti sei takanga tichiwana taper pakuvhiya kwakapfava. Yakaburitsa vacuum chuck yaive ine microscopic leak, ichibvumira 5-micron flex. Pazvinhu zvakawanda, hazvina basa. PaIncoloy 925, yakashandura oparesheni kuti iparare.
Iyo Special Alloys Niche uye Real-World Fit
Izwi rekuti 'special alloys' rinokandwa zvakasununguka. Kumugadziri, kazhinji zvinoreva 'zvinodhura uye zvakaoma.' Asi kune yekupedzisira-mushandisi mukugadzirwa kwemakemikari kana kugadzirwa kwemagetsi, zvinoreva 'chinhu chisingaputsi mushure memwedzi mitanhatu mumhepo inopisa acid.' Uku ndiko kukosha kwenyanzvi. Vanovhara mukaha iwoyo mukunzwisisa.
Uchitarisa chimiro chekambani seQSY's, iwo mutsara wakakosha musanganiswa: shell mold casting, investment casting, uye CNC machining kune alloys akakosha. Yakabatanidzwa vertically kuitira kuoma. Zvinoreva kuti vanogona kutora kuomarara kunotyisa, kutetepa-madziro Inoloy chikamu dhizaini - toti, musoro unopisa unopisa une machenera emukati - uikande kuburikidza nekudyara kune padhuze-mambure chimiro, wobva wapedzisa zviso zvekuisa chisimbiso paCNC, zvese zviri pasi pedenga rimwe. Izvo zvinhu hazvimbotakurwa pakati pechigadzirwa nechitoro chemuchina, izvo zvinoderedza njodzi yekusvibiswa uye, zvakanyanya kukosha, inochengeta ruzivo rwekuita ruchienderera.
Ini ndakabata neimwe nzira: iyo imba yekukandwa inopomera muchina shopu yekukonzeresa kushushikana, iyo muchina shopu inopomera imba yakakandwa yenzvimbo dzakaoma. Ihope huru. Kubatanidzwa kunocheka nepakati pazvo. Iyo inobvumira kune mhinduro zvishwe. Pamwe machinists anoona kuti imwe flange inogara yakaoma zvakanyanya kucheka zvakanaka. Ivo vanogona kufamba vachidzokera kuchikwata chevakatanga uye vape zano tweak kune annealing kutenderera kweiyo chaiyo geometry. Ndiyo goridhe rinoshanda.
Kukundikana seKumanikidza Basa
Iwe haunyatso dzidza zvinhu izvi kusvika chimwe chinhu chaputsika. Imwe yekukundikana kwedu kwedzidzo yaive seti yematireyi ekurapa kupisa akagadzirwa kubva kuIncoloy 601. Chikumbiro chaive chakatwasuka: kutakura zvikamu kuburikidza nechoto che carburizing. Vakararama chikamu chimwe muzvitatu cheupenyu hwaitarisirwa, vachiderera zvakanyanya. Ongororo yakaratidza kuti takanga tatsanangura iyo alloy nenzira kwayo yekuramba oxidation, asi isu takafuratira zvachose simba rekukwira pasi pemutoro pane iyo tembiricha chaiyo. Taive mumhuri yenyama chaiyo, asi giredhi risiri iro. 601 yakanaka, asi pamutoro wakaramba uri padanho iroro, DS (double-solution treatment) 800H ingave iri kufona.
Apa ndipo panokundikana machati ekusarudza zvinhu. Vanokuudza izvo zvinoramba corrosion, kwete izvo zvinobata chimiro pasi pehuremu hwayo pa2100 ° F kwemaawa 5000. Iyi mhando ye nuance ndiyo yaunobhadhara nemugadziri ane ruzivo. Ivo vangave vakakanganisa ivo pachavo kana kuti vaona mutengi achizviita. Kana ini ndichiona mutengesi anonyora zvakajeka mhuri senge cobalt-based uye nickel-based alloys, zvinoratidza kuti vajaira hurukuro idzi. Vanoziva kuti mubvunzo hausi chete Unogona kuzviita here? asi Ichapona here kwairi kuenda?
The Takeaway: Kudyidzana, Kwete Kutenga
Saka, paunenge uchitsvaga Inoloy chikamu, hausi kungotenga hunk yesimbi. Iwe uri kutenga mune yevatengesi ruzivo rwekuwedzera neanopisa dynamics, metallurgical phase shanduko, uye hutsinye machining fizikisi. Kudhirowa ndiko kwekutanga. Basa chairo riri munhaurirano: Izvi ndezvei? Chii chinonzi thermal cycle? Pane cyclic stress? Mutengesi akanaka achabvunza iyi mibvunzo. Iyo huru, senge iyo ine midzi yakadzika mukukanda uye kugadzira mhuka idzi, ichapa zano dzimwe nzira dzausina kufunga nezvazvo - zvishoma radius shanduko yekuvandudza kuyerera kwekukanda, kushivirira kuzorora kunochengetedza maawa makumi maviri emuchina, inokodzera zvirinani sub-giredhi yeIncoloy.
Pakupedzisira, chikamu chinosvika pachiteshi chako chiratidzo chekubatana ikoko. Haisi nhumbi. Icho chidimbu cheinjiniya yakagadziriswa, yakaomeswa mune yakasindimara, inoshamisa inobatsira alloy. Vavariro ndeyokuti chikamu ichocho chive chakavimbika zvisingashamisi mubasa zvokuti munhu wose anokanganwa marwadzo aidiwa kuti aite. Ndipo paunoziva kuti wazviita nemazvo.
