Nickel-Yakozwe na Superalloys

Nickel ishingiye kuri superalloys nicyiciro cyibikoresho bikora cyane bigenewe imbaraga zidasanzwe zubukanishi, guhangana n’imigezi, hamwe n’imiterere ihagaze ku bushyuhe bwo hejuru, ubusanzwe hejuru ya 540 ° C (1000 ° F). Ijambo "ryakozwe" risobanura ko ayo mavuta akozwe muburyo bwa nyuma binyuze muburyo bwa termo-mashini nko guhimba, kuzunguruka, cyangwa gusohora, bikavamo imiterere myiza, yerekana icyerekezo gitanga imiterere iremereye kandi yumunaniro ugereranije na bagenzi babo. Nizo nkingi yubushyuhe bwo hejuru buzunguruka mu kirere no kubyara ingufu, aho gutsindwa atari amahitamo.

Nickel-ishingiye kuri Ruswa-Irwanya Amavuta

Nickel ishingiye kuri ruswa irwanya ruswa nicyiciro cyibikoresho byuma byateye imbere byakozwe mbere na mbere kugirango bihangane n’ibidukikije bikabije. Urufatiro rwabo ni matelike ya nikel (Ni), isanzwe irwanya ruswa nyinshi, ikomatanyirizwa hamwe nibindi bintu byingenzi - cyane cyane chromium (Cr), molybdenum (Mo), ndetse rimwe na rimwe umuringa (Cu) na azote (N) - kugirango habeho umuryango utandukanye kandi ukomeye wibikoresho bikoresha imiti n’inganda bikabije. Nibisubizo byo gukemura mugihe ibyuma bitagira umwanda bitagihagije.

Ibyuma bishingiye ku byuma Byubushyuhe bwo hejuru

Ibyuma bishingiye ku byuma bikozwe mu bushyuhe bwo hejuru ni icyiciro cyibikoresho byuma bifite ibyuma (Fe) nkibintu byingenzi, byashizweho kugirango bigumane imbaraga zumukanishi no kurwanya iyangirika (nka okiside) mubushyuhe bwo hejuru, mubisanzwe mubipimo bya 540 ° C kugeza 760 ° C (1000 ° F kugeza 1400 ° F). Izina "ryakozwe" ryerekana ko ryakozwe nuburyo bukoreshwa nubushyuhe nko kuzunguruka, guhimba, cyangwa gusohora, binonosora microstructure kugirango bitange imbaraga zingirakamaro, guhindagurika, no guhimba. Bikora nkigiciro cyingirakamaro kandi gihindagurika cyane kumurongo mugari wubushyuhe bwo hejuru bukoreshwa, bikuraho itandukaniro ryimikorere hagati yicyuma kitagira umwanda na nikel ihenze cyane cyangwa cobalt ishingiye kuri superalloys.

Cobalt ishingiye kuri Superalloy

Cobalt ishingiye kuri superalloys nicyiciro cyibikoresho byuma bikora cyane bigamije gukomeza imbaraga zidasanzwe zubukanishi, guhagarara neza hejuru, hamwe no kurwanya ruswa kubushyuhe bwinshi cyane, akenshi bikarenga aho superalloys ishingiye kuri nikel itangira gucika intege. Nibikoresho fatizo byibice byingenzi mubidukikije bisabwa cyane cyane mu kirere, mu kirere, inganda za gaze, hamwe n’ubuvuzi. Imikorere yabo isumba iyindi ikomoka kuri materix ya cobalt-chromium hamwe nubunini bwinshi bwa karbide ya karbide.
