Iyo ba injeniyeri bagaragaje cobalt 6 uruganda ubushobozi, ntabwo basaba gutunganya gusa-barasaba gutekana kurwego munsi ya 200 MPa, guhuza microstructural guhuza ibice 500, hamwe no kwihanganira zeru gutandukanya karbide muri AMS 5387. Uku nukuri kubikorwa inyuma ya pompe ya cobalt alloy pompe ikoreshwa muri sisitemu ya hydraulic yo mumazi, nozzles ya peteroli yumuvuduko mwinshi, hamwe na moteri ikora ya valve. Twabonye imishinga myinshi ihagaze kuri prototype-ntabwo biva mubishushanyo mbonera, ahubwo bivuye mubuhanga budahuye nibikoresho no kugenzura inzira.
Impamvu Cobalt Alloy 6 Irasaba Kurenza Amaduka asanzwe ya CNC
Cobalt Alloy 6 (AMS 5387) ntabwo ari "ubundi superalloy gusa." 60% ya cobalt, 30% ya chromium, na matrise ya tungsten / nikel itanga imbaraga zidasanzwe zo kurwara, umunaniro ukabije, hamwe na ruswa yo mu mazi - ariko ku giciro cyo gutunganya cyane. Urusyo rusanzwe. Uturere dukungahaye kuri Carbide duhindura ibikoresho byo gukata. Uturere twibasiwe nubushyuhe buracika mugihe cyo gutunganywa nyuma yimashini. Twapimye igipimo cyo kwambara ibikoresho 4.2 × hejuru kuri Co-6 na Inconel 718 munsi y'ibiryo n'umuvuduko. Intsinzi ishingiye ku bintu bitatu bidashobora kuganirwaho: kugenzura microstructure yabanje gutunganywa, ingamba zo guhuza n'imikorere myinshi-axis igendanwa, hamwe no kugenzura ubushyuhe bwigihe mugihe cyo kurangiza.
Niyo mpamvu gutoranya-kurangiza guhuza ibintu birenze ubushobozi bwa CNC bwihariye. Uruganda rwa cobalt 6 rugomba gucunga urunigi rwuzuye - uhereye kumushoramari wogushora igishoro no kugenzura gukonjesha gukonje kugeza kugabanya imihangayiko mbere yo gukomera, hanyuma CMM iyobowe na CMM ikarangiza ikoresheje diyama. Umukiriya umwe AMS 5387 piston pompe amazu yananiwe kwipimisha imikorere kabiri. Impamvu? Utanga ibicuruzwa yakoresheje akonjesha ikirere aho gukoresha itanura rigenzurwa. Microcracks zakozwe kumupaka wintete-ntizishobora kugenzurwa n'amashusho, zica munsi yikizunguruka. Gukosora? Gukurikirana byuzuye kuva kuri bilet mbisi kugeza kumurongo wanyuma wo kuvura ubushyuhe, byagenzuwe kuri ASTM E112 na AMS 2750E.
Ubushobozi bune butandukanya Cobalt yizewe 6 Ibice byinganda nabamashini rusange
- Imirongo yemewe yo gutora: Ntabwo ari "twemera fagitire yawe ya Co-6 gusa." Ubushobozi nyabwo busobanura gushora imari murugo gushora hamwe na vacuum-pour ubushobozi, ceramic shell compozisiyo yemewe, hamwe nisesengura ryikurikiranwa rya buri cyiciro gishonga.
- Ibikorwa bya Hybrid: Urufatiro rwumusenyi Co-6 rusaba kwitegura kubutaka butandukanye kuruta gushora imari. Uruganda rwa cobalt 6 rugomba kugenzura byombi - kandi rukamenya igihe cyo guhinduranya hagati yuburebure bwurukuta, ubwinshi bwimiterere, hamwe nubushyuhe bwumuriro.
- GD & T-ibikorwa remezo byo kugenzura: Gupima 0.005 mm kwihanganira imyanya kumurambararo wa mm 120 ya Co-6 isaba ibirenze CMM. Irasaba laboratoire ya metero yubushyuhe, yemewe ya gage ishobora gukurikiranwa na NIST, hamwe nabakozi bahuguwe muri ASME Y14.5–2018 kwihanganira imyirondoro - ntabwo ari umurongo gusa.
- Kwemeza imikorere birenze geometrie: Ese iyo cobalt alloy plug ya kashe kuri 450 ° C na 180 bar? Nozzle ikomeza inguni ya spray nyuma yubushyuhe bwa 10,000? Inganda za cobalt nyazo 6 zikora ibizamini byubuzima byihuse - ntabwo ari igenzura gusa.
Ibyo Abaguzi birengagiza-kandi bakishyura nyuma
Amatsinda amwe atanga amasoko yibanda gusa kubiciro byavuzwe kuri buri gice. Ariko dukurikirana ibiciro byatsinzwe mumishinga 42 Co-6 mumyaka itanu. Ibintu bitatu byambere byihishe abashoferi bari: (1) gushushanya ubugororangingo ku gahato ibintu bitamenyeshejwe muri casting; (2) gusya kwa kabiri bisabwa kubera gukomera kutagaragara; na (3) gutinda-gutangira gukora kuva GD&T gusobanura nabi-cyane cyane kubijyanye na datum yerekanwe hamwe na silindrike na planari.
OEM imwe yu Burayi yishyuye 22% munsi yimbere kubice bya pompe ya cobalt 6 kubitanga bidahenze. Noneho yakoresheje amayero 187.000 mugusimbuza umurima nyuma yisuri ya valve itaragera. Intandaro? Umwanya utagengwa na interdendritic intera muri casting - upimye kuri 48 mkm ugereranije na ≤32 mm. Itandukaniro ryagabanije gukwirakwiza karbide, kwihuta kwambara. Raporo y'ibikoresho yagenzuwe ntabwo yari ihagije. Bakeneye ibyuma byambukiranya ibice kuri tombora - hamwe na protocole ya etching protocole hamwe na software yo gusesengura amashusho.
Kubaka Icyizere Mubikorwa Byinshi bya Cobalt
Uruganda rwa cobalt 6 rugira ibyiringiro binyuze mu mucyo - ntabwo ari icyemezo ku rukuta. Iyo abakiriya bohereje ibishushanyo, dusubiza mumasaha 48 hamwe na: (1) kwemeza ibikoresho biva muri raporo harimo na raporo y'ibizamini by'urusyo; (2) gutondeka inzira zishoboka zerekana amarira ashyushye cyangwa kugabanuka; (3) Ihamagarwa rya GD&T hamwe nuburyo bwateganijwe bwo kugenzura; na (4) urutonde rusobanutse "nta-kugenda" -ibintu tutazagerageza nta bufatanye bwa injeniyeri, nka radiyo y'imbere iri munsi ya 0.8 mm muri T800 yo mu cyiciro cya Co-6.
Ntabwo dusezeranya "ibihe byihuta byo kuyobora." Turemeza ko idirishya rihamye ryo gutanga kuberako ibikorwa byacu bitagira ingano birimo ubushobozi bwa buffer mu ziko ritunganya ubushyuhe hamwe na selile ya Co-6 yabigenewe - nta shyirahamwe risangiwe rifite ibyuma cyangwa aluminium. Buri gice cya cobalt 6 gitwara ibisobanuro byuzuye: umubare wubushyuhe bwibikoresho fatizo, guta indangamuntu, verisiyo ya gahunda ya CNC, indangamuntu yabakoresha, hamwe nigihe cyo kugenzura cyanyuma. Niba ikintu cyananiranye muri serivisi, amakuru arahari - ntabwo ari nyuma yo gutekereza, ahubwo yubatswe mubwubatsi.
Urebye imbere, imipaka ikurikira ntabwo yihanganira gusa. Nuburyo bwo guhanura kugenzura: gushyiramo thermocouples mugushushanya kugirango ugaburire amakuru nyayo mugihe cyo gutoranya ibipimo. Nuburyo uruganda rwukuri rwa cobalt 6 rugizwe niterambere-kuva mubukora reaction kugeza kubufatanye bwa injeniyeri. Kuberako iyo ubuzima cyangwa ibikorwa remezo bikomeye biterwa na cobalt alloy plug, kwizerwa ntabwo ari ibisobanuro. Nibipimo byonyine bifite akamaro.
