Ahantu ho gukoreshwa hifashishijwe ikoranabuhanga rya Thermal Spray

Mu myaka yashize, tekinoroji ya spray yumuriro yavuye mubikorwa bitoroshye byari bigoye kugenzura, mubikoresho bigenda bisobanuka neza aho inzira igenewe kuzirikana imitungo yibikoresho byabitswe hamwe nibisabwa.

Tekinoroji ya spray yubushyuhe ikomeje gutera imbere kandi porogaramu nshya igaragara kubikoresho byo guteramo ubushyuhe hamwe nibikoresho. Reka twige ibice byingenzi bikoreshwa muburyo bwa tekinoroji ya spray.

1. Indege

Ikoranabuhanga ryo gutera amashyuza rikoreshwa cyane mu bijyanye n’indege, nko gutera ibishishwa bya barrière yumuriro (bonding layer + ceramic surface layer) ku byuma bya moteri yindege. Gutera plasma, flame ya supersonic spray itera ibice, nka NiCoCrAlY na CoNiCrAlY, hamwe nubutaka bwa ceramic, nka 8% Y0-ZrO (YSZ) oxyde (irimo oxyde yisi idasanzwe) doping YSZ ihinduka, nka TiO + YSZ, YSZ + A10 cyangwa isi idasanzwe ya lanthanum zirconate ishingiye kuri okiside nka La (ZoCe) 024 nayo yarigishijwe nk'imyenda ya barrière yumuriro ku byumba byo gutwika moteri ya roketi5. Igice kinini cya rotor ya kajugujugu kugirango ikore ibikorwa bya gisirikare mu butayu kirangirika byoroshye n'umucanga. Gukoresha HVOF no gutera ibisasu bya WC12Co birashobora kunoza imyambarire. HVOF itera Al-SiC itwikiriye kuri magnesium alloy substrate yo mu ndege, ishobora kunoza imyambarire.

Inganda zibyuma na peteroli

Inganda zicyuma nicyuma nikintu cyingenzi cyo gukoresha spray yumuriro, kandi ninganda ya kabiri nini mubushinwa nyuma yo gukoresha spray yumuriro mubikorwa byindege. Mu mwaka wa 2009, Ubushinwa butanga ibyuma bya peteroli bingana na 47% by’ibicuruzwa biva ku isi ku isi. Nigihugu cyukuri cyicyuma, ariko ntabwo ari ingufu zicyuma. Ibyuma bimwe byujuje ubuziranenge biracyakenewe gutumizwa ku bwinshi. Imwe mu mpamvu zingenzi ni uko Ubushinwa butera ubushyuhe budakoreshwa cyane mu nganda zibyuma. Nkibisasu biturika tuyere, ubushyuhe bwo hejuru bwa annealing itanura, icyuma gishyushye cyerekana uruziga, uruziga rushyigikiwe, kugorora, kuzamura ingofero, kurohama, n'ibindi. kugabanya ibiciro, Kunoza ubwiza bwibicuruzwa, kandi inyungu ni ngombwa 19-0.

Mu nama ya ITSC 2011, impuguke y’Ubuyapani Namba yakoze iperereza ku ipatanti ijyanye no gukoresha imiti y’ubushyuhe mu nganda z’ibyuma ku isi. Ibyavuye mu bushakashatsi byerekana ko kuva mu 1990 kugeza 2009, ipatanti y’Ubuyapani yari 39%, patenti z’Amerika zagize 22%, patenti z’Uburayi zagize 17%, patenti z’Abashinwa zingana na 9%, patenti z’Abanyakoreya zingana na 6%, patenti y’Uburusiya ni 3% %, Igihugu cya Berezile gifite 3%, naho Ubuhinde bufite 1%. Ugereranije n'ibihugu byateye imbere nk'Ubuyapani, Uburayi, na Amerika, gukoresha imiti yo gutera amashyuza mu nganda z'ibyuma mu Bushinwa ni bike, kandi umwanya w'iterambere ni munini.

Raporo irambuye ijyanye n'inama kandi irimo ifu ya NiCrAlY na YO nk'ibikoresho fatizo, ifu ya spray ya NiCrAlY-Y0 yateguwe na agglomeration yo gucumura no kuvanga, naho impuzu zateguwe n'imbunda ya HVOFDJ2700. Wigane anti-kwiyubaka kwizunguruka ryitanura muruganda rwibyuma. Ibyavuye mu bushakashatsi byerekana ko ifu yifu yateguwe nuburyo bwo gucumura bwa agglomeration ifite uburyo bwiza bwo kurwanya anti-manganese okiside, ariko kutarwanya okiside ya fer. Impuzu zateguwe zivanze nifu.

Ikoranabuhanga ryo gutera amashyuza rikoreshwa cyane muri gaze, umuyoboro wa peteroli, no hejuru y irembo rya valve hejuru yo gutera ruswa no gutwika imyenda, inyinshi muri zo ni HVOF itera WC10Co4Cr.

3. Ingufu nshya, ibikoresho bishya, hamwe na gaz turbine

Ingirabuzimafatizo zikomeye (SOFCs) ubu zakozwe mu cyerekezo cy'isahani iringaniye hamwe n'amasahani yoroheje, harimo anode, electrolytite, cathodes,n'inzego zo gukingira. Kugeza ubu, igishushanyo mbonera cyibikoresho nubuhanga bwo gukora ingirabuzimafatizo zikomeye zimaze gukura, kandi ikibazo nyamukuru nikibazo cyo kwitegura. Tekinoroji yo gutera amashyuza (gutera umuvuduko muke wa plasma gutera, vacuum plasma spray) yabaye tekinoroji izwi cyane. Gukoresha neza uburyo bwo gutera amashyuza kuri SOFC nuburyo bukoreshwa bwa tekinoroji yo gutera amashyanyarazi mu mbaraga nshya, kandi binateza imbere iterambere ryibikoresho byo gutera. Kurugero, plasma yateye LaSrMnO (LSM) ibikoresho byo gutera, isosiyete yo mubudage HC.Starck yamaze gutangira gukora no kugurisha ibyo bikoresho nibikoresho bifitanye isano. Abashakashatsi bakoresheje kandi plasma yo mu bwoko bwa plasma itera kugirango bategure ibikoresho bya electrode LiFePO kuri bateri ya lithium-ion. raporo zubushakashatsi zijyanye.

Iterambere rya tekinoroji yo gutera amashyanyarazi ntaho ritandukaniye no kuvugurura ibikoresho. Buri nama mpuzamahanga yo gutera amashyuza izaba ifite raporo kubikoresho bishya bijyanye. Kubera ubushyuhe buke hamwe nigishushanyo cyihuse, imbunda ya K2 yo gutera spray ya GTV HVOF irashobora gutera ibyuma nkibyuma bya Cu, kandi umwuka wa ogisijeni uri muri 0.04% gusa, ugereranije no gutera imbeho. Ukoresheje sisitemu yo gutera HVOF yumuvuduko mwinshi, umuvuduko wicyumba cyo gutwika urashobora kugera kuri 1 ~ 3MPa, kandi flame itemba ni ubushyuhe buke n'umuvuduko mwinshi, utera 316L ifu yicyuma idafite imbaraga, uburyo bwo kubitsa bushobora kugera kuri 90%.

Uruganda rwa gaz turbine rwinganda rwatangiye gukoresha plasma yatewe nubushyuhe bwa barrière yumuriro, nka YSZ, LazZrzO, SmzZrzO, GdzZr20 sisitemu yo gutwikira, ikoreshwa cyane mumahanga kandi kuri ubu ni ubushakashatsi buzwi cyane mubushinwa.

4. Kurwanya imashini

Tekinoroji yo gutera amashyuza yamye nigice cyingenzi mubiterane mpuzamahanga byo gutera amashyuza murwego rwo kurwanya kwambara kuko hafi yimirimo yose yibikorwa byambaye imyenda irashwanyagurika, kandi gushimangira no gusana ni inzira zizaza ziterambere ryikoranabuhanga, cyane cyane hamwe nikoranabuhanga rifite a Ubwoko butandukanye bwibikorwa mu nganda zidashobora kwambara kandi binateza imbere iterambere ryibikoresho byangiza imiti. Imyenda ikoreshwa cyane idashobora kwambara ni: gusudira spray (flame spraying + remelting) NiCrBSi alloys, nazo zikoreshwa cyane kandi zigakoreshwa mu murima wihanganira kwambara, nka HVOF gutera ibiti bya FeCrNBC, arc gutera NiCrBSi nyuma yo gusubiramo Ubushakashatsi kuri microstructure no kwambara birwanya, nibindi.; Gutera HVOF, gutera imbeho ya tungsten ya karbide, hamwe na chromium karbide yifashishije ni byo bikoreshwa cyane kandi bigakorerwa ubushakashatsi mubijyanye no kurwanya kwambara; Inganda zo mu Bushinwa zo mu rwego rwo hejuru tungsten karbide ishingiye ku ifu ya spray yishingikiriza ku bicuruzwa bitumizwa mu mahanga, nk'indege Gusasa ikariso yaguye, kurohama, gukonjesha, n'ibindi. hari n'ibisabwa bishya kuri tungsten karbide ishingiye kumiti ya spray, nkubunini bwa powder isabwa ni -20um + 5um.

5. Nanostructures nibikoresho bishya

Nanostructures coatings, ifu, nibikoresho bishya nibyo byibandwaho mubushakashatsi mpuzamahanga mumyaka yashize. Nanostructured WC12Co gutwika byateguwe no gutera HVOF. Ingano yubunini bwa poro yatewe ni -10μm + 2μm, naho ingano ya WC ni 400nm. Isosiyete yo mu Budage DURUM yateje imbere umusaruro. Me lenvk yize ifu ya WC10Co4Cr yateguwe ukoresheje karbide ya tungsten ifite ingano zitandukanye nkibikoresho fatizo, nkubunini bwa WC ingano> 12um (imiterere isanzwe), ingano ya WC 0.2 ~ 0.4um (imiterere yintete nziza), ingano ya WC ~ 0.2um (imiterere-ingano nziza cyane); Ingano ya WC

12um (imiterere isanzwe), ingano ya WC 0.2 ~ 0.4um (imiterere yintete nziza), ingano ya WC ~ 0.2um (imiterere-ingano nziza cyane); Ingano ya WC

6. Gucapa ibinyabuzima n'impapuro

Ikoranabuhanga rya spray yumuriro rirakoreshwa cyane mubikorwa byubuvuzi, nka plasma vacuum, HVOF yateye Ti, hydroxyapatite, hamwe na hydroxyapatite + Ti ikoreshwa mu buvuzi (amenyo, ortopedie). Gutera ibintu biturika bya TiO2-Ag, nko gushira kuri Cu coil ya konderasi, birashobora kubuza gukura kwa bagiteri kandi bikagira isuku.
