Description
Vynález se týké ochranného povlaku pro lopatkuz titanové slitiny.
Lopatky z titanové slitiny jsou výhodné vz k tomu, že vykazují zvýšený poměr pevnost/objemová hmot-nost a pozoruhodnou mechanickou odolnost i v těch ne j-korozivnějěích prostředích. I přesto jsou lopatky z titanové slitiny, používa-né v parních turbinách, a to zejména v případě, kdy sepohybují zvýšenou obvodovou rychlostí, rychle poškozová-ny kapičkami vody, vytvářejícími se v páře.
Ukazuje se tedy nezbytným chránit obvod těchto lo-patek. Tento problém dosud řešen nebyl a pro uvedené lo-patky nebyla tudíž zatím navržena žádná ochrana.
Uvedený nedostatek odstraňuje ochranný povlak prolopatku z titanové slitiny obsahující 3 až 5 % vanadu a5 až 7 % hliníku, jehož podstata spočívá v tom, Že jetvořen podkladovou vanadovou vrstvou tlouštky 0,5 až 1,5mm a vnější vrstvou kobalto-chromo-wolf rámové slitiny pře-krývající podkladovou vanadovou vrstvu a obsahující 15až 28 $ chrómu a 3 až 8 % wolframu, přičemž zbytek je tvo-řen kobaltem.
Způsob uloženitohoto povlaku podle vynálezu jenásledující.
Na část lopatky určenou k povlečení se deponujevanadový prášek, načež se zvýší teplota prášku až na te-plotu lebce převyšující teplotu tání vanadu·
Na takto vytvořenou vanadovou vrstvu se potom de-ponuje prášek kobal to-chromo-wolf rámové slitiny, načež .se teplota tohoto prášku zvýší na teplotu, která je vyš-ší než teplota tání tohoto prášku, ale současně nižší nežteplota tání vanadu· Díky tomuto postupu se během prvního stupně inkor-poruje do lopatky z titanové slitiny minimální množstvívanadu· Stejně tak při druhém stupni je inkorporováníkobal to-chromo-wolf rámové slitiny do podkladové vanadovévrstvy velmi omezeno· Navíc roztavení této vrstvy slitinynebude mít žádný vliv na již vytvořenou vazbu mezi pod-kladovou vanadovou vrstvou a lopatkou·
Za účelem pokud možno nejvyššího omezení uvedenéinkorporace se s výhodou používá indukčního ohřevu s mo-bilním induktorem·
Ochranný povlak podle vynálezu zaručuje lopatce z - 3<1 - titanové slitiny při provozu v parní turbině dlouhodobouživotnost. Lopatka již není porušována kapičkami vody zpáry a to ani při vysoké obvodové rychlosti turbiny. V následující části popisu bude vynález blížeobjasněn na výhodném provedení, zobrazeném na připojenémvýkrese, na kterém
- obrésse 1 .zobrazuje perspektivní pohled na lo-patku podle vynálezu, . - obráa.frk 2 zobrazuje řez lopatkou z obrázku 1a - obráček 3 zobrazuje zvětšenou část řezu z obrés—ičS. 2.
Lopatka parní turbiny zobrazená na obrázku 1 se-stává z paty a ze sroubovnicově stočeného listu 2, ma-jícího náběhovou hranu 2. a odtokovou hranu 4. V horníčásti lopatky je uložena podél náběhové hrany na vněj-ší straně lopatky ochranná povlaková vrstva Tato po-vlaková vrstva se rozprostírá na asi nejméně jedné tře-tině šířky listu £ lopatky. Mezi listen £ lopatky a po-vlakovou vrstvou se nachází podkladová vanadová vrstva_6 /obr. 2/.
Lopatka je zhotovena .ze slitiny titanu obsahují-cí 6 % hliníku a 3,5 až 4, anadu..
Způsob uložení ochranné povlakové vrstvy je ná-sledující.
Povrch určený k povlečení se upraví klasickým způ- 'sobem, načež se na takto upravený povrch deponuje prak- o ticky čistý vanadový prášek /čistota vyšší než 90 %/ snízkou granulometrií smíšený s pojivém. Je třeba depono-vat takové množství vanadového práš|ku, aby se vytvořilafinální podkladová vanadová vrstva fc tlouštky vyšší než1 mm. Lopatka se potom vloží do vysokofrekvenční indukč-ní pece opatřené mobilním induktorek. Pec je bud evakuo-ÍJvaná nebo naplněna inertní atmosférou. Prostředí pece sepředehřeje a vanadová vrstva se pot ním diskem, který se na daném místě pm ohřívá 39 mm indukč znehybní na dobu 29 5 sekund a takto se postupuje vždy po .20 mm.
Teplota se takto lokálně zvýší na 1950 až 2000 C.
Teplota tání vanadu ýe 1900 C a teplota tání titanovéslitiny je řádově 2400 °C. Z toho vyplývá, že zatímcovanad je v roztaveném stavu, zůstává substrát z titanovéslitiny pastovítý, což je ideální k dosažení dokonalévazby v důsledku pouze omezené inkorporace vanadu dosubstrátu z titanové slitiny. V titanové slitině, kteráobsahuje asi 4 % vanadu, lze tolerovat inkorporaci /obr.3/ omezeného množství vanadu vedoucí lokálně ke struktu-ře beta. Tloúštká této vrstvy 7, slitiny s inkorporovánýmvanadem je velmi malá /nižší než 0,1 mm/.
Po ukončení postupu mobilního indukčního diskupřes celý povrch vanadové vrstvy se nechá teplota pece 6 klesnout na teplotu okolí..
Totom se na takto vytvořenou podkladovou vanado-vou vrstvu deponuje prášek kobalto-chromo-wolframovéslitiny smíšený s pojivém.
Tento prášek se deponuje 3 až 4 mm od okrajů podkládové vanadové vrstvy tak, aby nedošlo ke styku mezikobalto-chromo-wolfrámovou slitinou a substrátem z ti-tanové slitiny.
Potom se provede druhý stupeň zpracování v peciza vakua nebo v inertní atmosféře zahříváním vrstvy sli-tiny indukčním mobilním diskem na teplotu o 50 °C vyšší,než je teplota tání kobalto-chromo-wolframové slitiny/1200 až 1500 °C/. Tato teplota je podstatně nižší nežteplota tání vanadu, v důsledku čehož dojde k velmi ome-zené inkorporaci /viz obr.3/ kobalto-chromo-wolframovéslitiny do vanadu a vazba vanad/substrát zůstane nepo-rušena, přičemž vrstva 8 s inkorporovanou kobalto-chro-mo-wolframovou slitinou je velmi tenká /tenčí než 0,1 mm/. deponovaná vrstva slitiny bude mít tlouštku asi 1 ,5 mm.
Po snížení teploty pece až na okolní teplotu 7 se provede, jak to obvyklé, popouštění..
Zobrazené provedení vynálezu má pouze ilustrativhí charakter a vlastní rozsah vynálezu daný pefinicípředmětu vynálezu nikterak neomezuje. .
