NiAl budada xidha oo leh xoog isku xidhid adag
Sharaxaada
Waxaan ku hanweynahay inaan soo bandhigno laba badeeco oo ku saleysan budada NiAl: KF-2 iyo KF-6.Labadan alaab waxay isticmaalaan saamiyo kala duwan oo budada NiAl waxayna leeyihiin astaamo iyo codsiyo gaar ah.
KF-2 waxay isticmaashaa NiAl82/18, oo ka kooban 82% Ni iyo 18% Al.Alaabtani waxay ku habboon tahay codsiyada leh heerkulka ugu sarreeya ee 650 ° C.Waxay bixisaa daahan cufan, makiinad, oksidation-u adkaysta, iyo daahan u adkaysta oo leh waxyaabo isku xidhanHad iyo jeer waxaa jira falcelin kacsi ah inta lagu jiro habka buufinta, taas oo keenta in xoog isku xirnaanta oo heer sare ah oo ka sarreeya walxaha Ni5Al.KF-2 waxay ku habboon tahay hagaajinta iyo dib-u-soo-saarka birta kaarboonka ee mashiinka ah iyo birta u adkeysata daxalka, waxaana sidoo kale loo isticmaali karaa isku-xidhka lakabyada dhoobada iyo alaabta la xidho.
KF-6 waxay isticmaashaa NiAl95/5, oo ka kooban 95% Ni iyo 5% Al.Alaabtani waxay ku habboon tahay codsiyada leh heerkulka ugu sarreeya ee 800C waxaana lagu dabaqi karaa iyadoo la adeegsanayo hababka buufinta ee kala duwan sida ololka, APS, iyo HVOF.Waxa kale oo ay bixisaa daahan cufan, makiinad ah, oksidation-u adkaysta, iyo daahan u adkaysta oo leh sifooyin isku xidhan.Had iyo jeer waxaa jira falcelin exothermic ah inta lagu jiro habka buufinta, taasoo keentay xoog isku xirnaan oo heer sare ah.KF-6 waxa kale oo loo isticmaali karaa hagaajinta iyo dib-u-soo-saarka birta kaarboonka ee mishiinka ah iyo birta u adkaysata daxalka, iyo sidoo kale isku xidhka lakabyada dhoobada iyo alaabta la xidho.
Marka la soo koobo, labada KF-2 iyo KF-6 labaduba waa alaab budo ku salaysan oo NiAl ah kuwaas oo bixiya xoog isku xidhan oo aad u fiican oo xidha iska caabin.KF-2, oo ka kooban boqolkiiba hoose ee budada NiAl (NiAl82/18), waxay ku habboon tahay codsiyada leh heerkulka ugu sarreeya ee 650 ° C, halka KF-6, oo leh boqolkiiba sare ee budada NiAl (NiAl95/5), waxay xamili kartaa heerkul sare ilaa 800°C waxaana lagu dabaqi karaa iyadoo la isticmaalayo habab kala duwan oo lagu buufiyo.Labada alaabba waxay ku habboon yihiin hagaajinta iyo dib-u-soo-saarka birta kaarboonka ee mashiinka ah iyo birta u adkeysata daxalka, iyo sidoo kale isku-xidhka lakabyada dhoobada iyo alaabta la xidho.Doorashada u dhaxaysa KF-2 iyo KF-6 waxay kuxirantahay shuruudaha gaarka ah ee codsiga iyo heerkulka ugu sarreeya ee loo baahan yahay.
